WebNov 16, 2024 · Example 1 Find all the second order derivatives for f (x,y) = cos(2x)−x2e5y +3y2 f ( x, y) = cos ( 2 x) − x 2 e 5 y + 3 y 2 . Show Solution Notice that we dropped the (x,y) ( x, y) from the derivatives. This is fairly standard and we will be doing it most of the time from this point on. WebSeparation of variables is a common method for solving differential equations. Let's see how it's done by solving the differential equation \dfrac {dy} {dx}=\dfrac {2x} {3y^2} dxdy = 3y22x:
