Test for exactness then find the complete solution: y (x - 1) dx + In(2x - 2) + = dy = 0 xy2 + y3 = C a. yln(x - 1) + Iny + yln2 = C b. x'y - x tany = C ( 4 + y 2) ( 1 - x2 ) = C d.3 + y(1 - xy) = 3 e. Inx + cos 12 = x3x2 + xy2 - y3 = C A. xinx + In(Iny) = x + C h. ex + xlny + ylnx - cosy = C i, x + V x2 + y2 = C
