11.9 #1 Let I = the double integral of (x+y)dA over Rxy, the region bounded by 3x - 2y = 4, 3x - 2y = -2, x+y = -1, and x+y = 2. Evaluate I in xy coordinates. Next, let u = 3x - 2y, and v = x + y. Draw the region Rxy and the corresponding region Ruv. Finally, use the change of variables to evaluate I and notice how much it helps.

11.9 #1 Let I the double integral of(xty dA over Rxy, the region bounded by 3x 2y = 4, 3x-2 -2 x+y -1 and x+y 2. Evaluate l ln xy coordinates. Next, let u = 3x 2y and v = x + y Draw the region Rxy and the corresponding region Ruv. Finally, use the change of variables to evaluate l and notice how much it helps.
