1. Set up but do not evaluate the following triple integrals. Use cylindrical or spherical coordinates if possible. (a) = 1 + 2x + 2y dV where E is the region between paraboloids, E E={(x, y, z) | x + y - 3 z < 5 - x y}. P (b) (ay + sin(zy)) dV where P is the prism drawn below. (2,0,0) Z (0,0,3) 1950)
