Mathematics is a high scoring subject in class 11 among all the subjects.  Mathematics plays an essential role for all the students to get admission in the best engineering colleges. Even though the students have prepared the problem many times, sometimes they are not confident enough while writing the examinations. Here, the list of topics and concepts in class 11 mathematics such as finding the sides of a triangle using  Pythagoras theorem in trigonometry, limits and derivatives, probability and so on are provided.

Sets – Students are suggested to practice as many questions as possible. Learn the definitions properly and draw the Venn diagram if required to score good marks.

Relations and Functions – Domain and range are the essential concepts in this chapter. Learn all the graphs of the functions given in the section “some functions and their graphs.”

Trigonometric Functions – Learn all the trigonometry formulas. This chapter contributes to prominent importance among all the sections. Also, learn the trigonometric ratios of standard angles, and trigonometric identities with its proof.

Principle of Mathematical Induction – Most of the students find this chapter exciting; you need to analyse the question from the section. One problem will come from this chapter.

Complex Numbers and Quadratic Equations – This chapter is one of the easiest chapters in class 11 mathematics as it requires only less time to prepare for the exam. Inevitably the questions are asked from the concepts such as polar representation and quadratic equations with complex roots.

Binomial Theorem – Go through the questions from “General and Middle Term of a Binomial Expansions”. The calculation errors are likely to happen in this chapter.

Permutation and Combination – Learn the definition of permutation concepts when all the objects are distinct or not distinct, and determine the combination of the given problem.

Linear Inequalities – This part needs more practice to work with the system of linear inequalities in one variable and two variables.

Sequences and Series – Since all the topics in this chapter are almost related to each other. You cannot skip any exercise. Master all the formulas in this chapter to score more.

Straight Lines – Read all the straight lines formulas. Use proper labelling, figures in the problem that should be clean and neat.

Conic Sections – Practice all the concept in this chapter. Go through the concepts such as a parabola, hyperbola, circles, and an ellipse.

Introduction to Three-Dimensional Geometry – Determine how to find the distance between two points in the 3D space and also study the section formula.

Limits and Derivatives – The essential concepts in this chapter are product rule and quotient rule. Find the derivative of a function and determine how to apply the limits of a polynomial, trigonometric and rational functions. Use trigonometry table to find the corresponding value for the trigonometric derivative function.

Mathematical Reasoning – This chapter does not require computations. Get the description of the statement and examine its validity.

Statistics – Read the formulas like mean, variance, standard deviation, and coefficient of variation of a continuous frequency distribution.

Probability – Go through all the topics in this chapter. Understand the contrast between “with replacement” and “without replacement.”

We do upload exclusive content (at least once a week) on Education, Math, and general information.

I was trying to learn how to run Python scripts on a (remote) server. Amazingly, none of the Google first page results were relevant to what I wanted to do.

After much research (and searching around on the web), the steps that made it work are:

1. Type “ssh user@host” into the Mac Terminal. For example, if your username is bill and your host is microsoft.com, then type “ssh bill@microsoft.com”.
2. The system will prompt you for your password. Enter it carefully. (You may be locked out if too many incorrect passwords are entered. To unlock it, you will need to email your system administrator to unblock your computer’s IP address.)
3. Once you are into the server, type “python file.py” to run your Python script named “file.py” (You may need to change directory using the “cd” command if your Python file is in another folder. Type “dir” to see what is in your current directory.) To use Python 3, type “python3 file.py” instead.

That’s all to it!

I have checked all the aquarium shops at the famous aquariums at Clementi Blk 328 (also known as C328 LFS). They do not carry the Python Water Changer or similar products such as the Aqueon Aquarium Water Changer.

Hence, the most probable way of getting the Python No Spill Water Changer is through Amazon:

25 Foot – Python No Spill Clean and Fill Aquarium Maintenance System

I have personally purchased it and it arrived in good condition within a reasonably quick time. Some photos are attached below, with a stack of A4 paper as a size comparison.

There is also a related product by Aqueon that works basically the same way. According to online reviews it is also good, but possibly not as good as Python.

Aqueon Aquarium Water Changer – 25 Feet

The benefits of these water changers is that they can not only fill the tank (a simple hose can already do that), but they can also draw water out of the tank, without using electricity. Basically they use suction from the tap (siphon effect) to draw water out.

Not sure why Singapore aquariums (LFS local fish shops) do not import these products as it seems quite a time saver and reduces the need for carrying buckets.

Note that online stores (such as Qoo10 or Lazada) may appear to carry these items, but at a much higher price than if you purchase from Amazon directly. The reason is that they are from dropshippers — when you order from them, they will act as the middleman and order from Amazon to send it to you.

A video to demonstrate how it works:

Sending your child to nursery can be a very stressful decision. In fact, it is probably one of the most important decisions you will have to make for your child after he is born.

After all, the learning environment that they are exposed to at such a young age can have a significant impact on their long-term development. As education is so crucial for all children, it is critical that you dedicate the appropriate amount of thought to finding the right nursery for your child.

To help you with the search (it can certainly be an overwhelming one!), here are three essential things to look for when looking for the right nursery for your child.

1. A nursery that offers a  safe and stimulating environment

First and foremost, you want to ensure that you are sending your child to a nursery that provides a safe and stimulating environment. Children who are under age three need to be cared for in a manner that is different to what is required for older children, which is why it is advisable to send your child to a  nursery that is safe and offers a stimulating environment where your child can develop and thrive.

Take, for example, a nursery which is one of the top nurseries in Dubai. Here, children are not only in a safe environment but also in one that encourages them to move freely. The facilities ensure that there is the appropriate space for all parts of the curriculum to happen, as well as areas where children can be creative and use their imagination. Interestingly, these areas are designed to link in with “real-life experiences.”

More than just classroom areas, you want your nursery to have outdoor play areas so they can move and explore, as well as an indoor area with equipment for them to develop their physical balance and coordination.

2. A nursery with a strong curriculum — this matters so much!

As you may be able to tell, the key to finding a great nursery is to ensure that it has a wide array of facilities and offerings. However, the most crucial offering it must have is a strong curriculum as it is the curriculum that will be the backbone of your child’s experience at the nursery.

If you are living overseas, you may want to look for a British nursery in Dubai (or its equivalent) to ensure that your child is receiving the similar standard of a core curriculum that is based on the UK national curriculum.

When choosing between nurseries, make sure to take into consideration whether or not the staff administers the curriculum to each child’s unique learning needs and if they have a whole array of books and supplies that embrace all aspects of the curriculum. Ideally, the nursery you choose will offer extra-curricular activities and art classes such as music and dance intended to help your child develop their language, movement, and rhythm skills.

3. A nursery that encourages creativity

Undoubtedly, the best way for young children to learn is through play-based approaches.

More than just helping them gain basic knowledge, creative play promotes children’s social, cognitive, and physical development. Furthermore, activities that encourage children to be creative assist them in developing essential skills needed to interact, work, and cooperate with other human beings — yes, even at their age!

Therefore, when you are looking at potential nurseries, make sure to ask the staff how they utilize play and what they do to encourage the development of creativity. Additionally, you can ask them specifically how they structure the time for individual children’s interests. Last, but not least, pay attention to whether staff talk frequently to the children, even the younger ones, as this is critical to the development of the children’s communication and language skills.

Have you recently started looking at nurseries for your child? If so, what challenges are you facing when trying to identify which is the right one?

Alternatively, if you have already been through the process, what tips do you have to share with other parents who are currently struggling?

Open Meta Analyst Review

Open Meta-Analyst (http://www.cebm.brown.edu/openmeta/#) is a free software developed by professors in Brown University, for Meta Analysis.

Previously we reviewed another free software RevMan5. RevMan5 is very good at doing meta analysis with placebo control groups. What it is not very good at is doing single arm meta analysis, that is, for clinical trials without a control group.

Open Meta Analyst can do single-arm meta-analysis, with the benefit that it seems even easier and more user-friendly than RevMan (which is already quite good with a GUI).

There are some YouTube tutorials on how to use Open Meta Analyst to do analysis on RCTs (Randomized Clinical Trials) and more.

The user manual for Open Meta Analyst can be found at http://www.cebm.brown.edu/openmeta/doc/openMA_help.html. The good thing about Open Meta[Analyst] is that it supports both Windows and Macintosh.

According to many online reviews, an easy way to do Forest Plots (Forrest Plots) is supposedly to use the free RevMan software. RevMan (currently RevMan5) can be downloaded here. RevMan is a software geared towards medical statistical analysis.

RevMan is said to be the easiest method since at least it has a graphical user inferface (GUI). For total beginners, before even doing the Forest Plot, we need to learn how to enter the data into RevMan.

Overall, I think RevMan should be one of the easiest ways to do Forest Plots or meta-analysis. Furtheremore, the software is completely free. However, there is still a significant learning curve.

The original spelling is “Forest plot”, the name refers to the forest of lines produced.

In September 1990, Richard Peto joked that the plot was named after a breast cancer researcher called Pat Forrest and as a result the name has sometimes been spelled “forrest plot”. Source: https://en.wikipedia.org/wiki/Forest_plot

SCGS (Singapore Chinese Girls’ School) follows the IP system, with students having the option to continue to Eunoia Junior College, the newest JC.

SCGS IP Mathematics

SCGS IP Mathematics is still split into E Maths (Elementary Mathematics) and A Maths (Additional Mathematics). Content-wise, it is quite similar to O level Mathematics, except that the order of topics taught can be quite arbitrary and up to the school teachers.

SCGS Math Exams

On paper, SCGS has few “exams” and has totally eliminated the midyear exams. In actual fact, there are still numerous tests just that they don’t use the word “exam”.

For example, a sample syllabus for SCGS’ A Math Block Test for Secondary 3 students (around July) is:

1. Simultaneous Equations
2. Surds
3. Indices
4. Logarithms
5. Quadratic equation of expressions (alpha and beta)

The syllabus for the E Math Block Test is:

1. Quadratic Equations
2. Linear Equality / Inequalities
3. Indices and Standard Equations
4. Coordinate Geometry
5. Graphs of Function and Geometry (including quadratic graph, curve sketching and graphical solution, and graphs in practical situations)
6. Area & Volume of similar figures and solids
7. Congruence and similarity
8. Applications of Trigo (Angles of Elevation and Depression), Trigonometric ratios of acute and obtuse angles (excludes bearings and 3d shapes)
9. Lower Secondary Algebra

Applications of Sig Fig Calculator

Mathematics is all about presence of mind and high standard conceptual knowledge. These days, you have technological tools to perform the critical steps and provide you with 100% correct answers. When you talk about significant figures, students and other users normally make mistakes when they are not aware of the rules. If you don’t know about the regulations of determining significant figures, it would not be possible to come up with the correct answer.

·       Looking at an example

Consider that you have the number 25020. How many significant digits does this number have? If someone does not have complete information about the rules, he would be confused about whether zero would be significant or not. On the other hand, someone who is clear about the rules would not have any trouble in reaching the correct answer.

In accordance with the regulations of significant figures, the zero between 5 and 2 would be significant. This is simply because it is placed between two significant numbers. The zero that is present in the end would not be counted as significant because there is no whole number after that. It is all about being aware of the correct regulations.

Using Sig Fig calculator to determine results without stress

It takes a considerable span of time to determine the significant digits in a number. Even if you are well aware of the regulations, it is not an easy task after all. The use of a quality online calculator is an amazing option for users. The following points explain how you can benefit from this tool easily.

• Put your time to better use instead of counting the significant digits in a number. The Sig Fig calculator would complete the task in a much simpler manner. No effort is needed from the user. He does not have to sit and apply logic to determine the correct count of significant digits. When you enter the required number, the tool would determine the significant digits. In addition to that, you can round off a number to the number of significant digits as per your need. To find out more Math Calculators visit Calculators.tech.

Conversions done through a fast process

Determination of significant figures and rounding off are time consuming steps. If you have less time available, it would not be simple to get the conversion done in due course of time. The use of an online calculator provides a complete assurance that no time would be wasted.

• Quickness is a major plus point of this tool. Unlike a lot of other tools present online, this tool is much faster. It does not make the user wait or go into the non-responsive mode when the conversion is being done. The moment you enter a number and its rounding off digit requirement, the calculation would be completed in few seconds.

No apprehensions about limited usage

Most users do not prefer technological tools because they do not want to spend money on paid versions. This is actually a dilemma for most people. First of all, it is hard to find a completely free tool. Although a lot of options promise to be free but the user determines the actual condition when he starts using them. This calculator is completely free and no conditions are applied on the users.

Plus points for students

Even the thought of solving an assignment on significant figures can prove to be scary. These questions require a lot of concentration because students have to apply logic, implement the rules and perform other important steps to complete the questions. The Sig Fig calculator is a beneficial tool for all the students who want to submit correct assignments in due course of time.

• This calculator determines the significant digits in the number you want to round off. For instance, if you want to round off 256202, the tool would show that there are sig significant digits in this number. Similarly when you round it off, the number of significant digits would be shown again. In an overall manner, this tool provides immense help to students. First of all, they do not have to complete any calculations without using a tool. Similarly, they are able to complete multiple calculations in quick time.

• This calculator is quick and does not have a long processing time like a lot of other applications. Once you enter the input, the related calculations would be performed in a quick manner. You can be absolutely sure about the correctness of the results. However, you can only rely on the results if the calculator is dependable.

Conclusion

Significant figures in a number are determined after using certain rules. For instance, in the number 23604, zero would be counted as a significant number because it is present between two significant digits. The use of a quality Sig Fig calculator is a good alternative for students because it helps them in saving time and producing accurate calculations.

Gain Higher Grades through Well Written Assignments

One thing is for sure that the human being of the past was a better human being compared to the human being of today. The age that we live in is called ‘space age’. We have the most modern and state-of-the-art innovations at our disposal. We have the facility of the most modern equipment. How easy and quick it is for us in a various matter of life. The machine has made life extremely easy for us. Two decades back it took days in solving the various calculations. Now, computers have helped us in solving the most difficult of the calculations. Similarly, the ease of contact with the help of cell phones has made communication flawless.

Yet, humanity has lost the basic manners. The invention of the internet is one of the most brilliant achievement today. But, it has also opened a door to hacking. Extremely important data of various companies and countries have been hampered by the hackers. Millions of dollars have also been looted by them from the bank accounts of the people.

Internet is an open forum, anyone can come up, use it and write. The important thing is that your writing must be informative and user’s oriented. You have to go through from a Grammar Check process every time when you write assignments. It will helps you improve your quality of writing. There is no barrier to any class, color, religion, race, identity, etc. You are a butcher located in Mozambique, or a farmer in Bihar, or a businessman from Canberra. You are most welcome to market your skills, talents, and your products on the internet.

Simultaneously, it has opened a door to plagiarism. For example, you write about the finest tourist spot in the world, but later your content used in your site is copied by your competitor and used as it is. Consequently, you cannot grow- the Google algorithms will not let you and the competitor who plagiarized reach to the top of SERPs.

Importance of Quality Writing

Each and every person is creative somehow. The fact that nature has blessed every individual with a unique fingerprint. It suggests that not just the fingerprint but you can differ from even your twin brother in different traits, ideas, school of thought. You can be a supporter of a different ideology, however, your twin sister can be a proponent of some other ideology.

If you try you can be extremely unique, you would not need to copy the concept and idea of anyone else. It can be best analyzed from the fact that unique ideas have been a key to major innovations in history. People became renowned because they were able to generate a theory or philosophy different from their contemporary people.

From Avicenna to Newton, from Leonardo Da Vinci to Shakespeare, from Jean-Jacques Rousseau to Karl Marx. You will find a commonality that they all differ from each other. Had they been talking about the same ideas they would never have achieved the fame.

Threat to uniqueness

It is good to be positive but one must also analyze the academic corruption which has spread globally. Every idea once written on a piece of paper become an intellectual property right. It means that it is protected by international law as well as the domestic law of your country.

Billions of people have not heard of it, so they feel that anything that they see and read on the internet or in the books can be copied in their material as it is. Not even thinking that it is considered as plagiarism and the original writer has a right to sue cheater in the court of law. Plus, SERPs are highly affected on the internet.

The article which you post on your blog can become worthless for you if you do not follow proper techniques. The first thing that you need to do yourself is to be as original as you can. Don’t copy anything! You can read the blog written by another person, get an idea from him or her. In order to write something you also need to read a lot of material.
