So I'm asked to evaluate the integral by changing to spherical coordinates, .
I see how do to do all the plugging in, but I'm not sure how to determine the limits of integration. I know my radius is going to start at 0, but I want it to be limited by some function of . I can see that I want to be looking only at what's above the xy-plane and toward the positive side of x, so I want and . So I guess all that I don't see is what function bounds the radius on top.
