How to find the jacobian, transformed integral, and evaluated transformed integral step by step:

35. Use the indicated change of variables to evaluate the double integral. Sketch both the image in the xy-plane and the transformed image in the wv-plane in the space provided on your answer sheet. Give the Jacobian (line 1), the transformed double integral (line 2) and them evaluate (line 3). 1+ x2,2 dy dx ; x = u, y= R: bounded by xy = 4,xy = 1,x = 1,x = 4
