So most of the converting cartesian to polar integrals I've seen (both on this website and in class) involve some sort of circular integral region.
I was doing practice problems for my exam and I ran across one that does not and I'm stuck on how to solve it.
The integral is the following and the instructions say to solve it by converting to polar coordinates (which is annoying because this integral would be so easy to do normally):
$$ \int _0 ^1 \int_x^1 x^2 dydx $$
How should I approach this? I tried setting 1 = y and x = yand got 1 $=rcos(\theta)$ and $1 = tan\theta$ but these bounds don't really seem to help me integrate.
