1. The problem statement, all variables and given/known data Here is a solved problem: [PLAIN]http://img3.imageshack.us/img3/6948/97765276.gif [Broken] In part (e), they formulated the triple integral using the limits of integration they found by sketching the region. Is there a way we can find the limits of integration without sketching the region? To me, sketching this graph looks complicated, so I'm wondering if we can determine the limits for the iterated integral by just using the given equations... 3. The attempt at a solution I appreciate any help.
