please help with the following questions

Find the solution of the following equations. For each equation, first, determine the type of the category that the equation belongs to. (a) y = xy (1 + x2 (b) - cos - da - - sin -+ cos dy = 0 y (c) (2xy' - y) dx + 2xdy = 0 (d) y' + 2y = 22+ 2x (e) (x Inx - 2xy' ) dx - 3x2y-dy = 0 (f) da + - + sin y dy = 0 (g) (x + sin x + sin y) dx + cosydy = 0
