Evaluate the integral. 1 1-x2 2-x2-y2 1 dz dy dx -1 0 Vx2+yzUse spherical coordinates to evaluate the integral fffE Z dV where E is the region between the surfaces 962 + 3/2 + 22 = 1 and x2 + y2 + z2 = 4 with z 2 0. Evaluate the integral JJ 2xy dA where D is the first quadrant region given below. g (x) = Vx f(x ) =2-x2 D X
