Second order nonlinear nonhomogeneous differential equation

  1. Nov 8, 2011 #1

    I am having a little trouble solving this equation:

    [itex]\frac{d^2y}{dx^2} + \frac{A}{y}(\frac{dy}{dx})^2 + \frac{B}{(y+C)^2} = D - Ex[/itex]

    where A, B, C, D, and E are constants and, sadly, not related.

    So far, I've found this


    which would solve the first half of the equation. Is it possible to use a technique such as variation of parameters to solve the rest, or do I need a new approach entirely?

    Many thanks in advance for any help on this!
