Take $2 as the parallelogram bounded by a +y =0, a ty =4, x-y=0, andx - y 3 utv U - U Part a: Find the Jacobian (determinant) of the transformation using a = 2 and y 2 Part b: Set up the integral needed to evaluate Ary dx dy using the transformation and Jacobian in part a. Do not evaluate the integral
