Question

calc iii - converting an integral from polar to cartesian coordinates?

Answer 1

\[\int\limits_{\pi/2}^{\pi}\int\limits_{0}^{2}r^{3}\sin(\theta)\cos(\theta)drd(\theta)\]

Answer 2

alright I see what I was doing wrong, I was forgetting that there's an extra r added when you convert from cartesian to polar, so you gotta divide that r out first
