I have a naive question about nonlinear ODEs, supose I have one of such equations, and that it is homogeneous(adsbygoogle = window.adsbygoogle || []).push({});

NL(y(x))=0, (1)

and I know the solution. Then I want to solve the "associated" non-homogeneous equation

NL(y(x))=f(x) (2)

There is a method to attack this kind of problem using the fact that I know the solution of (1)?

I know that for linear ODEs I can use variation of parameters or Green functions, but what about nonlinear ones?

I want to check analytical alternatives before surrender to the temptation of numerical methods.
