The Jacobian of the transformation x=g(u, v) and y=h(u, v) is
Here
Hence, Jacobian
.
4. There is a region O in the plane whose area we wish to compute: JJ, dk dy. It turns out that if we let then in the new coordinates the region Q is described by osu s vand 2 sv s 3. Compute the are...
3. (2 Points) Let Q be the quadrilateral in the ry-plane with vertices (1, 0), (4,0), (0, 1), (0,4). Consider 1 dA I+y Deda (a) Evaluate the integral using the normal ry-coordinates. (b) Consider the change of coordinates r = u-uv and y= uv. What is the image of Q under this change of coordinates?bi (c) Calculate the integral using the change of coordinates from the previous part. Change of Variables When working integrals, it is wise to choose a...
