Answer: sky

First, we use L’Hopital’s Rule since the initial limit is a 0/0 indeterminate form.

\displaystyle \lim_{x\to k} \frac{sx^2y\sin (k-x)}{k^2-kx}=\lim_{x\to k}\frac{2xsy\sin (k-x)-sx^2y\cos (k-x)}{-k} (We have also used the product rule and chain rule in this step)

Substituting x=k into the expression, we get \frac{-sk^2y}{-k} which is equivalent to sky.

    That’s a nice problem. When I tried to solve it, I was surprised that my final answer’s is “sky”. I thought that I have done something wrong in my calculations, but I remembered you wrote “sky is the limit” 🙂
