Hey all,
If anyone has some hints on how to do this one it would be much appreciated:
Find the volume of the region given by x2 + y2 ≤ a2, 0 ≤ z ≤ x.
So I've gone to cylindrical polars, and threw in the Jacobian, r. If I integrate with my bounds being:
0 to a, 0 to pi, 0 to rcos(theta) of r dz d(theta) dr I'm getting 0 which can't be. What is it that I'm missing here. Any hint would be great.
