comment How to solve this: $F(x)=(x+y)e^{x-y}$, Find $\frac{\partial F}{\partial x}$ and $\frac{\partial F}{\partial y}$
And what is the problem? Just finding $\frac{\partial F}{\partial x}$ assume that $y$ is a constant. And vice verse.

comment Integral of inverse of square root of a quadratic
@Starior Because there are infinitely, but uncountable set of rings; and sum can only been used on a countable set of rings.
