Taking the derivative of $y^3-xy=2$, the correct result should be $y'=y/(3y^2-x)$.
However, when I use the impDif() function on TI Nspire CAS, the returned result is 0, as shown in the screenshot below.

I solved my own problem. It's just an interpretation issue with the CAS feature. It interpreted $xy$ as one variable named $xy$ instead of $x*y$. Solved when a multiplication sign is used in between x and y.
