Consider the transformation x = u2v2 and y = u3 + v3.
(a). Find out where the Jacobian of the transformation equals 0, and find the chambers in the u-v plane where the Jacobian is positive and the chambers where it is negative.
(b). Find the curves in the x-y plane that correspond to the rays in the u-v plane where the Jacobian equals 0.
(c). As you go counterclockwise about the origin in the u-v plane, describe the corresponding
motion in the x-y plane, using your answer to part (a).
