    Lightbulb 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

    You haven't actually told us what your problem is here. So what is the question?
