(3) Switch the order of integration for the double integrals below from dydr to drdy, or vice versa. (Hint: Draw the region on the ry-plane to understand the order.) You are not required to evaluate/solve the double integral, just rewrite it. d 2 - y + 2 x + y .2 a Vo 12 2 y + x 71 1 e dx dy 10 50/6 2 dx dy 14 2 x y Ln ( x + 2y ) dyd x 4) Find the general solution for each of the following separable differential equations a> dy 2 28 ax - y e by dy y + 6 b7 = dx 2x y 8 dj dy = (y-1) et y (1) = 2 ' 5) Find The solution for each of The following initial value problems , y(0) = 5 a> dy xs dx = y by dy = (2x + 32)y, y(0) = 1 dx cy ely dx 2x+1 -3 y (1) = 2 dx 1/2
