Consider the region E = {2² +9y² + 1622 <1} in the first octant. (a) Set up but do not solve the triple integral representing the volume of E using rectangular co- ordinates (x, y, z) (b) Use u = x, v = 3y, w = 42 and set up the triple integral representing the volume of E using (u, v, w) (c) Calculate volume of E
