another banal question
I'm supposed to transform to spherical coordinates. Is it simply to change x to r*cos(fi)*sin(theta) etc, change the limits to 0 to pi for fi and to 2pi for theta etc and multiply with the jacobi determinant r^2*sin(theta) or is there something I've gotten wrong or am forgetting?
also, I don't expect anyone to do this for me but just in case that someone wants to try it, the problem gives this identity as a hint
though I expect that to be fairly easy to do once I manage to change to spherical coordinates
(which when I examine it very closely now using cos^2+sin^2=1 makes it very easy if my assumptions are right)
