014 10.0 points Hint: Set u,v so that the resulting region in the u,v-plane has boundary of the form u=constant, v=constant for different con- stants. Then solve for x,y in terms of u,v This gives the desired change in coordinates. Evaluate the integral | = | | 2dzdy when D is the parallelogram having vertices 0(0, 0), P(2, 2), Q(8, 5), R(6, 3) I.
