# Math Help - Differentiate gen. solution of a inhomogeneous diff equation to find particular soln!

1. ## Differentiate gen. solution of a inhomogeneous diff equation to find particular soln!

General solution is
y = e ^(-2x) ( C cos 2x + D sin 2x) - ( cos2x - sin2x)
y complentary = e ^(-2x) ( C cos 2x + D sin 2x)
y particular = - cos2x - sin2x

thanks
