1. The problem statement, all variables and given/known data Let D be the triangular region in the xy-plane with the vertices (1, 2), (3, 6), and (7, 4). Consider the transformation T : x = 3u − 2v, y = u + v. (a) Find the vertices of the triangle in the uv-plane whose image under the transformation T is the triangle D. (b) Find the Jacobian of the transformation T. 2. Relevant equations 3. The attempt at a solution I think I got the answers, just checking to make sure. For a, I got the vertices; (-1,3),(-3,9) and (13,11). For b, I got 5.
