integral in cartesian coordinates that would be used to find the volume of the solid G bounded below by the elliptic paraboloid z =4 x 2 + y 2 and above by the cylindrical surface z =4-3 y 2 , [Hint: The upper and lower surfaces are on a platter with a cherry on top. Find the projection onto the xy-plane of the curve obtained when the two surfaces intersect.]

TEST3/MAC2313 Page 4 of 5 ______________________________________________________________________ 7. (5 pts.) Write down the triple iterated integral in spherical coordinates that would be used to compute the volume of the solid G bounded above by the sphere defined by ρ = 4 and below by the cone defined by φ = π /3. Do not attempt to evaluate the interated integrals. ______________________________________________________________________ 8. (15 pts.) Let f ( x , y )= x 2 y 2 on the closed unit disk defined by x 2 + y 2 1. Find the absolute extrema and where they occur.
