All right. So we're supposed to calculate the Jacoby in for the given transformation. So let's go through. Conquer the partial derivatives. A partial X district to you is to be partial X prospective e is to you partial. Why respect to you is to you partial vice for TV is negative. Two V botched the negative there. So the determinant that is negative for the squared minus for you squared and we're done.
