Solve the system u = x - y, v = x + y for x and y in terms of u and v. Then find the value of the Jacobian ∂(x,y)/∂(u,v). Find the image under the transformation of the triangular region with vertices (0,0), (1,1), and (1, - 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 =
The Jacobian of the transformation is J(u,v) =
