Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I want to solve equations of the form:

[tex]\dot x + x + y = sin(\omega t)[/tex]

[tex]\dot y = \dot x - y[/tex]

This is not a standard type of form for Runge-Kutta or linear systems of equations because

[tex]\dot y = f(\dot x, y, t)[/tex]

instead of

[tex]\dot y = f(x, y, t)[/tex].

Any hints or links to place for help would be appreciated! Thanks!
