$\frac{\partial F}{\partial y}\neq0\implies$ continuous contour line? (Implicit Function Theorem)

Can I solve $\lim_{(x,y)\to\ (0,0)} \frac{x^2y^2}{x^2+x^2y^2+y^2}$ by converting to polar coordinates?

Show that $\lim_{(x, y) \to (0, 0)} \frac{y + \sin x}{x + \sin y}$ does not exist.

Why are proofs not written as collections of logic symbols but are instead written in sentences?

Where Does the Hessian Matrix Come from (Why Does it Work)?

if $a^5+b^5<1$ and $c^5+d^5<1$ then prove that ${a^2}{c^3}+{b^2}{d^3}<1$
