Hello. Here is the original question http://phasedma.com/uploaded/TripleIntegral.JPG My difficuly is understanding the limits of integration--- party due to how the solid in question is "sliced" by those planes. I know how to visualize the parabolic cylinder, but I need help on 1. limits on integration, and 2. Order of integration. I doubt I would have to use polar coordinates since the region in question has no square roots... Thanks for you help I really do appreciate this.
