Introduction to Limits with its definition, types, examples, and rules

Limit is an essential topic in Calculus, it is used in almost all important and main topics like differentiation and integrals. Limits refer to something that confines, restricts, and bounds.

In mathematics, the concept of limit is based on closeness, it is normally used to assign values to some functions at that point at which no values are defined. In calculus, a limit is a value on which a function approaches the output.

The history of this mathematical concept is very old and authentic. Limits were firstly introduced by the Italian mathematician Archimedes almost 2300 years ago. He introduced the idea of limits to measure curved surfaces and figures.

In this post, we’ll study the basic definition, rules & types of limits with examples.

Definition:

According to Wikipedia:

“In mathematics, a limit is a value that a function (or sequence) approaches as the input (or index) approaches some value”

Formula of limit:

The formula of limit is usually written as:

We can read it as the limit of f(x) as x approaches c equal to L

• f(x) is the function.
• c is the limit value.

Types of limits:

Limit has three types.

• Right-hand limit
• Left-hand limit
• Two-sided limit

Right-hand limit:

The right-hand limit is an approaching value of f(x) as the x approaches c from the right side.

The plus sign represents that the limit value comes from the right and must be greater than c.

Left-hand limit:

The approaching value of a function F(x) as the x approaches c from the left side is called the left-hand limit.

The negative symbol represents that the limit term comes from the left and must be less than c.

Two-sided limit:

The two-sided limit represents that the left-hand limit and right-hand limit exist and both have the same result. No sign is used for the two-sided limit.

How to calculate limits in calculus?

To evaluate the limit, follow the below examples.

Example 1: Calculate the limit of 12x3 – 5x2 + 21x + 32 / x5, when x approaches 2.

Solution:

Step 1: Take the given function and apply the limits.

f(x) = 12x3 – 5x2 + 21x + 32 / x5

c = 2

Step 2: Apply the limits notation separately by using the sum, difference, and quotient rules

Step 3: Write the constants outside the limits.

Step 4: Now put the limit value.

To get rid of these long calculations you can use an online limit calculator with steps.

How to use the limit calculator:

1. Enter the function in the input box.
2. Select the variable.
3. Select the limit type.
4. Enter the limit.
5. Cross-check your input box from the display box.
6. Hit calculate button.

Example 2:

If the function is not giving a finite answer after putting the limits then we use the L’hospital rule to solve that kind of function.

Example: Let us consider a function f(x) = (3x3 – 9x2) / 3x – 9 as x approaches to 3.

Solution:

Step 1: Take the given function and apply the limits.

F(x) = (3x3 – 9x2) / 3x – 9

c = 3

Step 2: Now apply the value of the limit.

Step 3: To remove the indeterminate form apply the L’hospital rule. Take the derivative of the upper and lower side of the function separately.

d/dx F(x) = d/dx (3x3 – 9x2) / d/dx (3x – 9)

F(x) = (9x3-1 – 18x2-1) / (3(1) – 0)

F(x) = (9x2 – 18x) / 3

F(x) = 3x2 – 6x

Step 4: Now apply the limit value again.

Summary:

In the above article, we have studied the basic definition of Limit, its types, and the basic history of limits. After reading this article carefully you will be able to solve almost all the problems related to this topic. The basic intent of the L’hospital rule is discussed above.

Why Asians Are Good At Math – Jimmy O. Yang Math Joke

Jimmy O. Yang is a famous US comedian of Chinese origin. This joke on “Why Asians Are Good at Math” is quite hilarious.

Warning on the YouTube video: Strong Language for Singapore/Asian standards (Recommended at least Age 16 or up to watch it.)

For US standards, apparently it is normal language, YouTube doesn’t even censor it.

To fully understand Jimmy’s joke, you need to understand what is a TI-83 Plus, which is covered in our recommended calculators page.

Jimmy is a talented Asian immigrant who excels in the standard repertoire of: playing ping-pong, violin and Math!

YANG: Absolutely. I grew up playing ping pong.

GARCIA-NAVARRO: (Laughter).

YANG: I grew up playing the violin. And I was extremely good at math.

How to develop students’ interest in mathematics

For interest in Math, it is totally understandable that many students may find math boring. One way to overcome it is to try to think of each Math question like a puzzle or game (like a Sudoku or Crossword Puzzle). Solving a Math question correctly should bring joy and a sense of achievement just like completing a stage of a game or a puzzle. And the more questions one solves, the better one gets at it.
“Mathematics, rightly viewed, possesses not only truth, but supreme beauty—a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show.”
― Bertrand Russell
In the Singapore context, basically, Math is quite compulsory in SG education system (up till JC, even arts subject combinations requires math), but once JC is over one can skip Math entirely in university. So a secondary student just have to work hard for math for the upcoming few years, and “get it over with”, if he/she really does not like math. Similarly for Chinese, students need to work hard up till Secondary 4, score well and be exempted in JC. Math can be considered the “easiest” subject to get A, as long as one gets the answer correct he/she will get the full marks, many students complain that getting A for English or other humanities subjects like Literature is much harder due to strict or subjective marking.
The important thing is not to give up. Currently, in the Singapore education system it is quite common for students to “fail” exams (fail as in score below 50), especially in secondary school and JC internal exams. It is very possible to improve upon working hard after the failure.
“Trust me, its normal, I never passed a single A math test/exam during my sec 3/4 school years, got A2 for O levels in the end. (Mugged really hard after prelims) What matters is understanding the content I feel.”
– This student never passed a single A math test/exam up till prelims but eventually got A2 for O levels after “mugging” really hard after prelims.

trust me youre not alone. from mid sec 3 to prelims in sec 4 i got F9 all the way. but then in the end i got an A2 in olevels. one thing u need to know is to NEVER stop believing in yourself. keep on pushing urself all the way till the finishing point. aft seeing my score for prelims, i alm gave up but i told myself to atleast PASS amaths and i’d be satisfied with it. i started spamming my TYS, practice as much as i could. never give up and whenever in doubt just ask ur cher. it rly helps! atb and ik u can do it:))

dude chill. i got 8% for mye in sec 3 for A Math. form teacher told me drop the subject, but i didnt. ended up o level got A2. just do work given and practice more.
– This guy even more “power”, he got just 8/100 for Mid-year exams, but improved to A2 in O Levels.

Time needed for each O Level E Maths / A Maths Question

Just to reblog an old post on how much time to take per mark per question for ‘O’ level or IP Math. The above guideline applies for both E Math and A Math, Paper 1 and Paper 2.

The basic guideline is 1.5 min per mark.

So for a 2 mark question, the time taken should be 1.5×2=3 min.

For a 5 mark question, the time taken should be 1.5×5=7.5min.

This is the slowest speed allowed in order to finish the entire paper (there is no time to check). Hence, if one wishes to have some time for checking, it is recommended to do questions at a faster speed of around 1.2 or 1.3 min per mark.

E Maths / A Maths: Maximum time per question

Paper 1: 2 hours (120 min) — 80 marks

Max. Time taken per mark: 1.5 min per mark

Paper 2: 2 hours 30 minutes (150 min) — 100 marks

Max. Time taken per mark: 1.5 min per mark

In O Levels Maths, speed and accuracy is very important indeed!

Best Calculator for Linear Algebra and Calculus

Many universities and colleges allow students to use advanced graphical calculators for exams in math courses, including linear algebra, calculus and engineering. Having the appropriate calculator can prove to be a huge advantage in terms of getting the correct answer and saving time. Even if the handwritten manual working is required, a good calculator can help to check the correctness of the answer.

Best Calculator for Linear Algebra

The key calculations in linear algebra include calculating the inverse and determinant of matrices. Additional features that are useful in calculators include the ability to calculate eigenvalues, eigenvectors, and RREF (reduced row echelon form). These features can be great time savers (or at the minimum, useful tools for checking your answer), as matrix operations are often tedious and prone to human error.

Our first choice would be Texas Instruments TI-84 Plus CE Color Graphing Calculator, Black. This is one of the flagship calculators by Texas Instruments. This type of calculator is something like a smart phone, you would need to download free apps that will greatly magnify its power in solving Linear Algebra equations. Some of the linear algebra capabilities of the TI-84 Plus are:

• Calculate adjoint of a matrix
• Solve Simultaneous Equations
• Calculate dot product, cross product of vectors
• Calculate inverse of matrix (when matrix is invertible)
• Calculate LDU decomposition, Cholesky factorization
• Calculate Eigenvalues and plot the characteristic polynomial
• Compute the Frobenius norm of a matrix
• Perform Gram Schmidt orthonormalization
• Calculate null space (kernel) if a matrix
• and more!

This calculator is good enough up till senior undergraduate level or even graduate level, for computational intensive modules, such as computational physics or any module that requires linear algebra calculations.

For a more budget-friendly version, you may check out the Texas Instruments TI-84 Plus Graphing Calculator, Black which is essentially the black and white version of the TI-84 Plus CE Color.

Or for an even cheaper option, you could opt for the older version Texas Instruments TI-83 Plus Graphing Calculator which still supports the linear algebra apps.

Often, linear algebra courses include applications to differential equations as well, which overlaps with the next topic on Calculus.

Update: For the latest TI-85/86 models, there is a new “Matrix Mode” inbuilt into the calculator that can perform basic matrix operations (including inverse) and other advanced operations such as LU Decompositions, and finding eigenvalues/eigenvectors.

Note that paradoxically, the newer TI calculator models may be cheaper than the older ones.

Best Calculator for Calculus

For Calculus, the important features that a calculator should have are the ability to perform numerical differentiation and integration. There are also some amazing apps for TI83/84 that can perform symbolic differentiation, that is, find the derivative of a function in symbols (not just the numerical value at certain values of x).

So once again, the TI-84 Plus CE Color Graphing Calculator, White is a good suggested calculator for Calculus modules.

If your budget (and course requirements) permit, you should definitely check out the Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator with Student Software (PC/Mac). CAS stands for “computer algebra system”, which means that the calculator is capable of producing symbolic results rather than just numerical results.

The TI-Nspire™ CX II features a deSolve wizard function for reducing syntax errors in solving differential equations. The TI-Nspire CX can even do vector calculus. It is a very powerful smart calculator that is essentially a mini-computer.

TI Calculator Alternatives

In my experience as a student and educator, TI (Texas Instruments) calculators dominate the market and are generally considered a good choice. But there are other viable alternatives that can also be considered good for linear algebra, calculus or engineering math.

A popular alternative is Casio calculators, for instance Casio fx-9750GII Graphing Calculator with icon based menu. Color white. An immediate advantage of Casio calculators is their low price.

The Casio fx-9750 (and related series) calculator is able to calculate determinant of matrix as well as basic matrix operations such as multiplying matrices, finding the inverse of matrix, etc.

As mentioned above, the main advantage of Casio graphical calculators is their low price. For advanced features, the TI calculators definitely trump over the Casio calculators.

Another alternative to TI calculators are the HP graphical calculators. Let us check out the most powerful HP calculator, the HP 50g Graphing Calculator.

The HP 50g Graphing Calculator has a “MatrixWriter form” to facilitate the entry of matrices. It is essentially like an Excel spreadsheet. Once the matrix is entered, there is a myriad of functions that can be applied, such as finding the determinant, trace, transpose, and rank of a matrix.

In terms of Calculus, the HP 50g can perform a wide range of calculus functions such as:

• Limits and derivatives
• Anti-derivatives and Integrals
• Calculate the Taylor/Maclaurin series of a function symbolically (up to 4-th order relative power, i.e., the difference between the highest and lowest power in the expansion is 4)
• Partial Derivatives (Multivariate Calculus)
• Multiple Integrals such as double integral
• Vector Calculus such as del, gradient, divergence, curl
• Differential Equations
• Fourier series

The list above is quite impressive! Overall, the HP 50g Graphical Calculator is a very strong competitor to the TI series graphical calculators.

Best Calculator for Engineering

Engineers often need to use Linear Algebra, as well as Calculus. Hence, the best calculator for engineering often overlaps with the best calculator for linear algebra or calculus. Do check out our above reviews and pick the calculator that best suits your needs.

In general, we have the below summary.

Best Budget Calculator: Casio graphical calculators, such as Casio fx-9750GII Graphing Calculator with icon based menu. Color white.

Safe choice, all-round best calculator: TI Texas Instruments Calculator, for instance the iconic Texas Instruments TI-84 Plus CE Color Graphing Calculator, Black

Super Powerful Calculator (very advanced and comprehensive features): HP 50g Graphing Calculator

H2 Math Tuition 2020

H2 Math can prove to be quite challenging for many students. Historically, the distinction rate is 50%, meaning that half of the student population will get an ‘A’ grade.

However, note that those 50% can be heavily represented by the top schools RI, HCI, NJC where almost all students get ‘A’. At the end of the day, the ‘A’ level students are facing heavy competition from the IP cohort (who were absent from the O levels).

Tough topics in ‘A’ level H2 Math:

Case study: I tutored a student (from China) studying in NJC for H2 Math. Although she was quite a strong student with good Math foundation (definitely above average), nevertheless the NJC H2 Math paper was set so tough that she only scored 50+ out of 100 in the prelims. Many students in her NJC class outright failed for the prelims (below 50 marks). There were some weaknesses in her H2 Math skills, for example certain topics like Integration and P&C, and also carelessness issues. After several months of tutoring, noticeable improvements were observed. In the end for the actual ‘A’ levels, she managed to score A grade for H2 Math.

When religion (Pope Francis) met science (Stephen Hawking)

Also interesting is that the founder of the “Big Bang” theory was a Catholic priest!

A Catholic priest, Fr. Georges Lemaître, is “Father of the Big Bang Theory”

The meeting was cordial, in spite of their diametrically opposed views regarding the existence of God.

[A surprising encounter took place between the pope, who holds that God’s mercy is infinite, and a scientist who rejects the existence of God due to the infinity of the Universe. On December 2, Stephen Hawking participated in a conference in Rome on the Big Bang, today considered the most widely accepted theory for the origin of the universe—a theory proposed by the Catholic priest Georges Lemaître (1894-1966) in 1927. ]

Pope Francis and Stephen Hawking: Faith and reason reach out to each other

British scientist Stephen Hawking and Pope Francis met face to face on November 28 in the Vatican, just days after that renowned astrophysicist had confidently declared that asking “what was before the Big Bang” is meaningless, since it “is like asking what lies south of the South Pole.”

The meeting between these two charismatic figures, world-renowned representatives of the Catholic Faith (Francis) and of reason based on scientific knowledge (Hawking), was rare but cordial, although they have completely opposite stances regarding the idea of God.

Pope Francis considers God to be an infinitely merciful Father, greater than the Universe He created — the same Universe that Hawking has been studying for decades and which he believes arose from nothing, without divine intervention.

Hawking stated that “the discovery of the expansion of the Universe” — the “big bang” theory —  has been one of the “most important intellectual discoveries” of recent times. However, “With James Hartle from the University of California, I worked out what physical conditions the early universe must have, if space-time had no boundaries in the past. Our model became known as the ‘No-Boundary Proposal,’” said Hawking, during the Science and Sustainability conference organized by the Pontifical Academy of Sciences at the Casina Pio IV in the Vatican.

Although the Big Bang is a well-accepted theory among experts, and it is fundamental for the formation of galaxies and planets, there is still no convincing answer to what happened before the explosion, what caused it, and consequently the reason for existence. Nevertheless, the theory fits into a logical explanation of the universe. “The message of science is that we are the children of logic and not of chaos,” explained Italian nuclear physicist Antonino Zichichi, a colleague of Hawking, in an interview with Vatican Radio.

Stephen Hawking dies aged 76

RIP Stephen Hawking.

The British physicist was known for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.

“We are deeply saddened that our beloved father passed away today,” a family statement said.

At the age of 22 Stephen Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.

Researchers studying the Flynn effect have found that scores on IQ tests have actually improved over time.

This is an interesting read for parents and students. Basically, IQ is a complex notion that is dependent on various factors, including environment and educational factors.

Source: ThoughtCo

You’ve probably heard someone lament the state of “kids today”: that current generations aren’t as smart as the ones that came before them. However, psychologists who study intelligence have found that there isn’t much support for this idea; instead, the opposite may actually be true. Researchers studying the Flynn effect have found that scores on IQ tests have actually improved over time. Below, we’ll review what the Flynn effect is, some possible explanations for it, and what it tells us about human intelligence.

What Is the Flynn effect?

The Flynn effect, first described in the 1980s by researcher James Flynn, refers to the finding that scores on IQ tests have increased in the past century. Researchers studying this effect have found wide support for this phenomenon. One research paper, published by psychologist Lisa Trahan and her colleagues, combined the results of other published studies (which included a total of over 14,000 participants) and found that IQ scores have indeed increased since the 1950s. Although researchers have documented some exceptions, IQ scores have generally increased over time. Trahan and her colleagues observed, “The existence of the Flynn effect is rarely disputed.”

Why Does the Flynn Effect Happen?

Researchers have put forward several theories to explain the Flynn effect. One explanation has to do with improvements in health and nutrition. For example, the past century has seen a decrease in smoking and alcohol use in pregnancy, discontinuation of the use of harmful lead paint, improvements in the prevention and treatment of infectious diseases, and improvements in nutrition.

As Scott Barry Kaufman writes for Psychology Today, “The Flynn effect serves as a reminder that when we give people more opportunities to prosper, more people do prosper.”

In other words, the Flynn effect could be partially due to the fact that, over the twentieth century, we’ve started addressing many of the public health issues that prevented people in earlier generations from reaching their full potential.

Another explanation for the Flynn effect has to do with societal changes that have occurred in the past century as a result of the Industrial Revolution. In a TED talk, Flynn explains that the world today is “a world where we’ve had to develop new mental habits, new habits of mind.” Flynn has found that IQ scores have increased the most rapidly on questions that ask us to find similaritiesbetween different things, and more abstract types of problem solving — both of which are things that we need to do more of in the modern world.

Several ideas have been put forward to explain why modern society might lead to higher scores on IQ tests. For example, today, many more of us have demanding, intellectually rigorous jobsSchoolshave also changed: whereas a test at school in the early 1900s might have been more focused on memorization, a recent test might be more likely to focus on explaining the reasons for something. Additionally, more people today are likely to finish high school and go on to college. Family sizes tend to be smaller, and it has been suggested that this may allow children to pick up on new vocabulary words while interacting with their parents. It’s even been suggested that the entertainment we consume is more complex today.

Trying to understand and anticipate plot points in a favorite book or TV drama may actually be making us smarter.

Singapore’s Only Live Turtle And Tortoise Museum Is Closing This March & Here’s How You Can Help

I have visited the Turtle Museum around 2015/2016. It was a very impressive collection of turtles and tortoises, right in the middle of the Chinese Gardens. Even includes rare species like the Alligator Snapping Turtle.

Quite sad to hear that they are closing down. Land price / rental in Singapore is notoriously expensive, so I can understand that having a space to house all those turtles is very hard in land-scarce Singapore. I would estimate that their rental would easily be at least S\$10,000 a month for such a large space. They have kept the ticket prices low at just \$5 for each person.

Do help by donating (https://gogetfunding.com/turtles-need-a-home/), or even just sharing this news will help. Every share leads to more views and potentially more donors.

Singapore’s Chinese Garden is known for its imperial styled pagodas and arch building, but within all that beauty lies another: Singapore’s very own Live Turtle & Tortoise Museum.

A Guiness World Record Holder, the museum holds over 500 turtles and tortoises from 40 different species, ranging from the most dangerous alligator snapping turtle to the world’s 2nd largest tortoise species, the Giant Aldabra. All this is run by Connie Tan and a handful of workers, as part of her family’s legacy.

Unfortunately, this marvel may soon no longer be – the museum is scheduled to be evicted from Chinese Gardens by 31st March. We headed down to understand what drives Connie to keep this museum alive against all odds.

Stolen A-Level scripts: 75 of 238 affected students will re-sit Chemistry Paper 3

Sincerely wishing good luck to those retaking their exams. It is certainly not easy, especially for boys who by that time will be in National Service. Also, for a fact-intensive course like Chemistry, with each passing month it gets harder since one’s memory would not be as fresh.

SINGAPORE: Of the 238 students whose A-Level Chemistry scripts were stolen in the United Kingdom last year, 75 have opted to be re-examined for the affected paper, the Singapore Examinations and Assessment Board (SEAB) told Channel NewsAsia on Monday (Mar 12).

The students, who received their A-Level results on Feb 23, are from Anderson JC, Anglo-Chinese JC (ACJC), Hwa Chong Institution (HCI) and Nanyang JC (NYJC). The stolen scripts were for Paper 3, which consists of free-response questions and carries a weightage of 35 per cent of the entire H2 Chemistry examination.

The final A-Level grades of the affected students were derived through a projection. But given the “unique circumstances”, the affected students were given the option to re-sit the H2 Chemistry Paper 3 in April or November, and have the better of their two grades recorded in their A-Level result slip and certificate.

Those who wished to register for the re-examination had to do so by Friday (Mar 9).

SEAB said that of the 75, there were 28 students each from AJC and ACJC, seven from HCI and 12 from NYJC.

Out of the total, 57 of the candidates registered for the re-examination in April, while 18 registered for the re-examination in November

The magic (and math) of skating on thin ice without falling in

Very interesting video. Do try to imagine the sound of the ice and check out the video to confirm your guess. Very surprising sound! It is a pity that not many countries have such ice to skate in.

The main mathematical principle is Archimedes’ Principle:

Congelation ice, while a solid form of water, does bend slightly and acts like an elastic plate buoyed by the water below. To Anje, it’s Archimedes buoyancy principle in action.

“A body partially immersed in water is buoyed by a force equal to the weight of the water displaced by the body,” he said.

Stepping onto an inch-and-a-half thick piece of lake ice — much less doing laps on it — is a no-go for most people. But for experienced Swedish skaters Henrik Trygg and Mårten Anje, few things top skating on thin ice.

In December, still photographer Trygg filmed Anje skating on 1.8 inches of fresh ice on a lake outside Stockholm. The resulting mini-documentary— filled with the eerie, laser-like sounds of bending ice — went viral in February.

One shot shows the ice, commonly called “black ice,” visibly bending under the skater’s weight. Which raised the question: Why doesn’t this thin frozen surface break?

For the answer, we turned to Anje, a 35-year veteran of nordic skating whose day job is calculating risk. He is a mathematician and actuary at a consulting firm.

Brand’s Essence of Chicken Effectiveness

Students studying hard for exams may often feel mentally tired, though technically they are sitting on the chair most of the time. This is because the brain actually uses around 20% of the body’s energy despite the brain only being 2% of total body weight.

Not to mention if the child is in a sports CCA, in addition to being mentally exhausted, he/she is also physically tired after all the training. Having energy after school has ended is very important, as 90% of the important revision takes place at home after school has ended.

Is Essence of Chicken Effective

There is quite a lot of scientific research on the effectiveness of chicken essence:

Effectiveness of Essence of Chicken in Improving Cognitive Function in Young People Under Work-Related Stress

Effects of chicken essence on recovery from mental fatigue in healthy males

Chicken essence is basically condensed chicken soup, which contains a lot of vitamins and amino acids in easily absorbed form. This may be even better than eating vitamin pills which may not be absorbed well by the body.

Brandsworld E-Store is the official online store of Brand’s, where you can buy Brand’s Chicken Essence online for your children, or even yourself. Other than Chicken Essence, Brand’s also sells other health products such as Birds Nest, and Collagen.

The Tinkering Studio @ Science Centre Singapore cordially invites you to interact with John Edmark, inventor, designer and artist who teaches design at Stanford University in Palo Alto, California. His most recent work is a series of animated sculptures called Blooms which endlessly unfolds and animates as it spins beneath a strobe light.

Come join us for this talk where John will share his work with logarithmic spiral structures, Fibonacci numbers, and the Golden Ratio (Ф), and how it all led to his inventing Blooms. His masterful illusions are the results of a marriage between art and mathematics.

RSVP: to Ms Jenny Leong by 18 March 2018.

Pre-registration is required for your complimentary entry into the Science Centre.

Wakin Chau 周华健 was a Math Major at University

Something interesting that not many people know?

Wakin Chau was born in a rice store owned by his family in Sai Ying Pun, Hong Kong. Growing up as the fourth son in his seven-member family, Wakin learned to play the guitar when he was about 13 years old. In 1979, he left for Taipei to major in mathematics at National Taiwan University. During his college years, he sang and played folk songs in local coffee shops. This activity was a tradition among NTU students, and it is how Wakin learned to sing in Mandarin, which would be key to his future as a music-maker in Taiwan.

Probably one of his most famous songs is “Friends”, 朋友.

Wanton Noodles

As a Chinese born and grew up in northern part of China, I’m very familiar with noodles. Yet, its very difficult for me to cook southern pattern noodles well, like rice noodle, Hokkien mee. I tried wanton noodles before and it didn’t turn out well. I guess the main reason is that I didn’t pay much attention to the difference between southern noodles and northern noodles. Northern noodles are more hard and thicker. They need more time to be cooked. That is completely different from southern ones.

I corrected my way of cooking wanton noodle this time.

Noodle was bought from supermarket and so was the wanton wrap.

1. Prepare the wanton filling:

Minced pork (100g), some shrimps ( around 10), 1 stalk spring onion, 1 small slice ginger, 3-4 water chestnut. Chop them together and let them be sticky to each other.

French Math “Coniques” : ellipses, paraboles, hyperboles.

French Math is unique in treating these 3 conic curves: (ellipse, parabola, hyperbola), always starts from the first principle – a la the Cartesian Spirit “I think therefore I am” (我思故我在).

“Catersian” Analytical Geometry was co-invented by two 17CE French mathematicians René Déscarte and Pierre de Fermat.

Note: The “elliptic curve” is a powerful geometry tool used in Number Theory (proved the 350-year-old Fermat’s Last Theorem in 1994 by Andrew Wiles), also in the most advanced Encryption algorithm.

Chinese Competition (Total Prize of \$20,000 SGD)

Quite a good deal if you are also interested in obtaining the HSK (Hànyǔ Shuǐpíng Kǎoshì) Grade 6 Qualification (HSK六级成绩报告), which will be useful if you study/work in China in the future.

Entry fee is S\$90 for test takers at Singapore location. For Malaysia location, it is RM 250.

By the way, Grade 6 is the highest grade in the HSK, designed for “learners who can easily understand any information communicated in Chinese and are capable of smoothly expressing themselves in written or oral form.”.

This is open to both students and adults. Previous years youngest participant is 10 years old. Also, there is a “Singaporean and Malaysian Citizen” Category, together with an “International” Category.

As we can see from the photos, there is a mixture of adults and children taking this test, there is no age limit.

The Pros & Cons of the French Elitist Grandes Ecoles

The French Grandes Écoles System is characterized by one unique Ultra-Selective Exams – “Concours” (pronounced as Kongu) or 科举 (pronounced in Chinese dialect Fujian as “Kogu”) a la the 1,300- year Chinese Imperial Exams dated since 600AD till 1905. Napoléon Bonaparte had great admiration of the Chinese mandarin meritocractic selection system, he was influenced by the Jesuit priests who were mostly working in China coastal province Fujian, decided to implement “Concours” for his newly established military engineering college ”École Polytechnique” (aka ‘X’).

Like any system, there are always two sides : the pros & the cons. Kogu served China well for 1300 years, producing top mandarins who ruled China with the most intelligent scholars through layers of selective exams from county (乡试选拔”秀才”) to province (省试选拔 “举人”) to the capital (京都 殿试选拔 “进士” – 前三名状元 /榜眼 / 探花).

Top 20 Math Books on Machine Learning / AI

The first 4 books (by Strang, Lang, etc) are the Masterpieces.

• Linear Algebraby Strang. He writes math like few folks do, no endless paragraphs of definitions and theorems. He tells you why something is important. He wears his heart on his sleeve. If you want to spend a lifetime doing ML, sleep with this book under your pillow. Read it when you go to bed and wake up in the morning. Repeat to yourself: “eigen do it if I try.”

Royal Hunt QR Codes

The first two tiers of rewards are Polar and Ya Kun \$2 vouchers. The final tier is a chance to win the top prize (worth \$15,000); a seven-night Mediterranean Cruise for two on board Royal Caribbean’s state-of-the-art Symphony of the Seas. The prize also includes return economy airfare to Barcelona, Spain.

The Royal Hunt starts on March 2 and ends on March 20.  Here is how you play:

2.  Activate the app and check the e-map. The e-map will show the locations of 20 MRT stations — Ang Mo Kio, Bedok, Bugis, Buona Vista, Chinatown, Choa Chu Kang, City Hall, Dhoby Ghaut, Harbourfront, Jurong East, MacPherson, Punggol, Tampines, Tanjong Pagar, Raffles Place, Serangoon, Stadium, Tiong Bahru, Toa Payoh and Woodlands;

3. Select any of the MRT stations indicated on the e-map and look for the Royal Hunt posters within each MRT station;

4. Scan the golden anchor QR code embedded within each Royal Hunt poster to drop the anchor onto each tile on the scorecard. After scanning each QR code, go to the next location to collect the subsequent Golden Anchors;

5. After collecting five Golden Anchors, you will be assigned a specific location to collect the sixth and final Golden Anchor;

6. After collecting the sixth Golden Anchor, you complete the scorecard and end the game. You will then be in the running to win the top prize.

Six Golden Anchors must be collected to complete the scorecard.

Hence, basically you need to complete and scan 6 QR codes out of the possible QR codes: Ang Mo Kio, Bedok, Bugis, Buona Vista, Chinatown, Choa Chu Kang, City Hall, Dhoby Ghaut, Harbourfront, Jurong East, MacPherson, Punggol, Tampines, Tanjong Pagar, Raffles Place, Serangoon, Stadium, Tiong Bahru, Toa Payoh and Woodlands QR codes. If you only want the first two tiers of rewards, 1 or 3 QR codes respectively instead of 6 QR codes will be sufficient.

No homework, full-day school curriculum to help level playing field (Proposal, not implemented yet)

Full-day school is quite a drastic measure to combat tuition. Also, unless full-day means 7am to 7pm, it is unlikely to be different from the status quo.

Any parent with children in secondary school or JC is aware that school is already pretty much “full-day” as of today, from 7am to 5pm at the minimum on most days (including CCA). Hence, there is not much room to get more “full-day” than now. JC students are known to stay much later for CCA, probably some are already having schedules from 7am to 7pm, which more than qualifies as “full-day”.

Also, even if full-day school (say 7am to 7pm) is implemented, there seems nothing to stop students from having tuition during the weekends, or on weekdays 8pm-10pm.

Probably most students would not be too pleased at having a full-day school. If I were still a student, I would definitely be more stressed out by the full-day school. I would much rather have some homework but end school early. I would imagine teachers won’t be too happy too, full-day school for students means full-day school for teachers, since obviously some if not all teachers must stay back to supervise the students.

Most unhappy would be tutors, for obvious reasons. Probably if this is implemented, most tutors will have to change jobs. 😛

The underlying idea to level the playing field is good and makes sense though. Possibly make the full-day optional so that those who want to stay back and have the full-day can do so, those who want to leave can also do so.

Source: TodayOnline

SINGAPORE — To level the playing field for children from less advantaged socio-economic backgrounds, and break out of the country’s tuition culture, Nominated Member of Parliament Chia Yong Yong has suggested that all schools adopt a full-day curriculum.

That way, the children will complete their homework during school hours, and be able to spend more time on “push-frontier practicals” aimed at training them to become more comfortable in tackling problems and to grow an appetite for risk-taking. These qualities are essential traits for the current technological revolution, also known as Industry 4.0, she said.

In her Budget debate speech in Parliament on Wednesday (Feb 28), Ms Chia said the current academic model “runs the risk of not harnessing the potential of all our young people” who do not have access to enrichment and tuition classes. As a result, those from more advantaged socio-economic backgrounds who have access to these classes will outperform their peers.

Stressing that “every school is a good school, but not every home is equal”, the lawyer said the current system has been “abused” such that inequality continues to be perpetuated and deepened.

NUS to offer veterinary medicine

Good news to those who want to be a vet! (Previously the usual option is to study in Australia). The veterinary medicine programme looks very rigorous, taking a total of 5.5 – 6.5 years, more than the duration of NUS medicine (5 years). At the end of the day, travel to Australia is still required though as it is a concurrent degree with University of Melbourne.

Source: Today

In a first for Singapore, the NUS will offer undergraduates a chance to study veterinary medicine through its new concurrent degree programme with the University of Melbourne. At present, only Ngee Ann and Temasek Polytechnics offer diploma courses respectively in veterinary bioscience and veterinary technology. The programme, which will take between 5.5 to 6.5 years to complete, will take in 10 students for a start, with the number to increase if demand is high.

They will spend 1.5 years at NUS to grow their foundation, followed by one-year abroad at the University of Melbourne to read modules in Year 1 of the Doctor of Veterinary Medicine (DVM). After that, the students will spend another three years in Melbourne to complete their studies. While they will pay prevailing NUS and University of Melbourne tuition fees during their time in Singapore and Australia, Singaporean students can expect to pay about 15 per cent less in tuition fees for the DVM portion of the programme as compared to the four-year course in Melbourne as an international student. They will graduate with an NUS bachelor’s degree in life sciences and a graduate-entry, professional veterinary science qualification from the University of Melbourne.

Higher paying job than Doctor / Lawyer

We encourage top students to look beyond the traditional Singaporean jobs of Doctor / Lawyer as there are new emerging jobs that can equal or even surpass the pay of Doctor/Lawyer.

At the end of the day, do also consider your passion and aptitude, which may be more important than the salary. No point being stuck in a high paying job that you absolutely hate.

Do share this post with your children/relatives/classmates who may be choosing their courses after receiving their ‘A’ level results.

Source: Todayonline

SINGAPORE — A high-paying job as a doctor or lawyer has traditionally been the career path that many Singaporeans aspire to. But there is now a new kid on the block, with double degree graduates in business and computer science joining the ranks of top earners here.

According to the latest graduate employment survey released by three local universities on Monday (Feb 26), fresh graduates from Nanyang Technological University’s (NTU) business and computing science double degree programme commanded a median starting salary of S\$5,000 last year, up from S\$4,600 in 2016.

The median salary for the batch of 20 graduates matched that of their peers who graduated from the law and medicine faculties. They were also in demand with employers, as they recorded a 100 per cent overall employment rate.

Meanwhile, fresh computing science graduates were also among the highest paid last year. Those who graduated from this course in NTU got a median starting pay of S\$3,850 last year, up from S\$3,500 in 2016. Their counterparts from the National University of Singapore (NUS) received S\$4,285 – S\$285 more than in 2016.

However, rankings differed for 75th percentile salaries — the base salary of the top 25 per cent of the batch — as SMU-schooled lawyers emerged as top earners at S\$5,840, compared to NUS doctors’ starting pays of S\$5,305, and S\$5,362 for NTU’s business and computer science graduates.

Growth of starting salaries in law and medicine was tepid, however, as law graduates from NUS and SMU only received about S\$100 and S\$150 more respectively last year, while NUS doctors banked in about the same amount as their seniors.

238 Singaporean A-level H2 Chemistry exam scripts stolen in the UK

Unbelievable. I think this should be the first time such an incident happen. Hope the affected students will get a fair grade despite this unfortunate incident.

Source: Yahoo

A parcel containing 238 scripts for the 2017 GCE A-Level H2 Chemistry Paper 3 was stolen from a courier in the United Kingdom, the Singapore Examinations & Assessment Board (SEAB) said Friday (23 February).

Students from four junior colleges – Anderson JC (58 scripts), Anglo-Chinese JC (60 scripts), Hwa Chong Institution (60 scripts) and Nanyang JC (60 scripts) – were affected, SEAB said in a statement. They comprised 3 per cent of the 8,843 school candidates who sat for the paper.

The theft occurred on 16 November 2017 while the parcel was in transit from Cambridge Assessment to the examiner. The case is under UK police investigations and the scripts have not been recovered.

What to do if did not do well for A Levels

For those who did not do well for A Levels, do not be overly disheartened. Though it may seem like the end of the world, it is not, and there are other options available to you.

Firstly, check out this post by Digital Senior, where they discuss 7 alternative routes for those who did not do well for A Levels. The 7 alternative routes are: Polytechnic, SUSS (Full time/part time), Overseas universities, SIM-UOL, NTU/NUS part time degrees, SIT, and lastly retaking A levels.

Secondly, check out this post by Mothership, featuring 10 inspirational stories of Singaporeans who did not do well for A levels but persevered on to achieve success in their respective fields.

Thirdly, check out this Reddit post, where advice is given about failing A levels.

Also, do dispel the myth that failing GP will lead to zero chance of entering university. It is still possible to enter local university with failed GP, though certain courses like Law are ruled out.

If I failed my General Paper (GP) at the Singapore-Cambridge GCE A-Level exam, can I apply for admission?

Yes, you can apply for admission. However, if you failed GP, you will not qualify for certain courses such as Law which will require a GP grade of at least ‘B3’ (for old syllabus), ‘B’ (for new syllabus) or a good pass in Knowledge & Inquiry (KI) (for new syllabus).

Applicants who do not possess the necessary English Language qualification will be required to take the Qualifying English Test (QET), if offered admission. Those who fail to fulfill the QET requirement will not be allowed to graduate – click here for details.

Finally, just to share a quote about success and failure in general, not just A Levels:

The results of the 2017 Singapore-Cambridge General Certificate of Education Advanced Level (GCE A-Level) examination will be released on Friday, 23 February 2018.

Good luck to all collecting their A Level results today!

Check out our post on BMAT Book Recommendations for NTU Medicine, and also Alternate Admission Route to NUS Computing.

1. The results of the 2017 Singapore-Cambridge General Certificate of Education Advanced Level (GCE A-Level) examination will be released on Friday, 23 February 2018. School candidates may collect their results from their respective schools from 2.30pm that day.

2. Private candidates will be notified of their results by post. The result slips will be mailed on 23 February 2018 to the postal address provided by the candidates during the registration period. Private candidates who have SingPass1accounts can also use their SingPass to obtain their results online via the internet Examination Results Release System (iERRS) on the Singapore Examinations and Assessment Board’s website (www.seab.gov.sg) from 2.30pm on 23 February 2018.
