1. Give a rough sketch of the region and evaluate the following integrals or show diver- gence. (You may need to change the order of integration.) dA, where D is the triangle with vertices (0,0), (0, 1) and (1, 1) e"+V dy dx. (page 288, #4(b)) (c) cos y dA, where D is the triangle with vertices (0,0), (4,4) and (0, 4) e+2y dy da. (e) ye!+-dA, where D is the first quadrant region below y = 1 and between and y2 sin T y cos r dy dx. (page 293, #4(a)) cos y sinir + y2) dA where D = [0.2] Ã [0, 2ju [1,3] x [1.3] -sin (-) dA, where D = (z, yje R2 |-ã x
