Homework 6: Problem 18 Previous Problem Problem List Next Problem (1 point) Let I = SSp(x2 - y?) dx dy, where D = {(x, y) : 3 0,y> 0} Show that the mapping u = xy, v = c - y maps D to the rectangle R = [3, 5] x [0, 6]. (a) Compute O(r, y)/a(u, v) by first computing (u, v) /(x, y). (b) Use the Change of Variables Formula to show that I is equal to the integral of f(u, v) = v over R and evaluate. (I,y) (a) Ju, u) (b) 1 =
