5. Evaluate ff fopcoso dV where E is the solid bounded below by the cone o = 7/6 and above by the sphere p = 2 in spherical coordinates. 6. Consider the region R bounded by x2 + 4y? = 1. Define u = x + 2y and v = x - 2y. Write r and y in terms of u, v. Find the image of R in the uv-plane under this transformation
