(1 point) Suppose a change of coordinates 7' : R - R from the wu-plane to the xy-plane is given by x = e" "" cos(5v), y = e "" sin(5v) . Find the absolute value of the determinant of the Jacobian for this change of coordinates. o(x, y) = det = o(u, V)(1 point) Suppose a change of coordinates 7' : R - R from the uv-plane to the xy-plane is given by x = 50+u+5, y=1 -u+v. (a) Find the absolute value of the determinant of the Jacobian for this change of coordinates. o(x, y) = det = o(u, V) (b) If a region D* in the wu-plane has area 7.32, find the area of the region T(D* ) in the xy-plane.
