## Homework Statement

Change the Cartesian integral into an equivalent polar integral and then evaluate.

## Homework Equations

x=rcosθ

y=rsinθ

I have:

∫∫r

^{2}cosθ dr dθ

The bounds for theta would be from π/4 to π/2, but what would the bounds for r be?

I only need help figuring out the bounds, not with the evaluating.

The answer for the problem is 36 (or so says the back of the textbook).
