ok so i found the roots of the equation where m = 1 and then i got my yc equation which was also pretty straight forward.
what i am having problems with is the yp equation,
i made my guess to be: Ax + Bx^3e^x <--- my book said i was wrong?
any help would be appreciated...
That might be overkill, but it might not. A hunch: any of those constant that are superfluous will be easy to solve for, I think. So I don't think you'll waste too much time doing it this way.
