o(x,y) Solve the system u= x - y, v= x + 3y for x and y in terms of u and v. Then find the value of the Jacobian v) Find the image under the transformation of the triangular region with vertices (0,0), (3,3), and (3, - 1) in the xy-plane. Sketch the transformed region in the uv-plane. The function for x in terms of u and v is x =]. The function for y in terms of u and v is y =].
