1. The problem statement, all variables and given/known data Find the limits of this region of integration, and write all possible equivalent iterated integrals given combinations of dz, dy, and dx. 2. Relevant equations none that are really 'equations'? 3. The attempt at a solution In particular, I'm having trouble with the order dy dz dx, as in: ∫∫∫ dy dz dx I can get -1 and -√z for the bottom and top limits of the first integral (∫ dy) but I'm having a harder time finding the limits for ∫∫ dz dx in the z-x plane. I get 0 and y^2 for the top and bottom limits of that ∫dz, which shouldn't be right since it both should be functions of (x) and not of (y). I'd appreciate a pointer or hint. Thanks!
