I have to browse my college notes first lol: d^2y/dx^2 + 3(dy/dx) + 2y = x^2 Rewriting, such that dy/dx = D: (D^2 + 3D + 2)y = x^2 Left side becomes: m^2 + 3m + 2 Factoring, (m+1)(m+2) m = -1 I think the question is like this . x = e x/y . Taking log on both sides , we get log x = x/y Or ylogx = x Now differentiating both sides w.r.t x , we get yd/dx(logx) + logx d/dx(y) = d/dx(x) [ Product rule ] or y/x + logx dy/dx = 1 Re arranging , logx dy/dx = 1- y/x = x-y/x Again Re-arranging , we get dy/dx = (x – y)/xlogx Solve the de dx y dy x cot tan Sol: Given, dx y dy x cot tan dx x dy y dx y dy x dx y dy x cot tan tan 1 cot 1 cot tan Integrating we get, c ecx y x c y c x y dx x dy y cos sec sin sec ln sin ln sec ln cot tan Which is the required solution.

Group the terms of the differential equation. Move the terms of the y variable to the left side, and the terms of the x variable to the right side. Integrate both sides of the differential equation, the left side with respect to y, and the right side with respect So times the derivative of xy squared. So that's our left-hand side. We aren't done taking the derivative yet. And on our right-hand side, the derivative of x is just 1. And the derivative with respect to x of y is just going to be minus-- or I could write-- negative dy dx.
