Using polar coordinates to solve a double integral
I am confused on how to go from rectangular components to polar ones. I'm going to show you the problem I'm trying to solve and the steps I took to solve it. I would really be glad if anyone could take a look and tell me if I'm doing something wrong.
Thanks for viewing,
The question is:
Use polar coordinates to solve the following integral.
I thought that and formed two semi-circles (the positive one in the 1st and 4th quadrant, the other one in the 2nd and 3rd quadrant), which formed a circle.
Then the double integral in polar coordinates would be:
Is that right?
