Hey lytwynk.
Are you integrating a double integral over the region that is bounded by a circle with radius 2*a with centre (0,0) or are you integrating a line integral with the boundary equal to that same circle?
Hello,
I am studying for my math final and our prof gave us a review but without any solutions or hints. I don't really understand this problem so if anyone could help me out here I would appreciate it.
Question: Find the integral of the polar function h(r, theta) = r cos(theta) , r >= 0, over
the circle r = 2a cos(theta) .
Again I would appreciate the help.
Hey lytwynk.
Are you integrating a double integral over the region that is bounded by a circle with radius 2*a with centre (0,0) or are you integrating a line integral with the boundary equal to that same circle?
I'm going to assume its over a 2D region defined by a circle since r >= 0.
Hint: With regards to your limits the integral will have r going from 0 to 2a and theta going from 0 to 2*pi.
