anonymous 5 years ago solve the diff eq using the method of variation of parameters y'' -3y' +2y= 1/(1+e(-x))

I am not sure about the particular solution, but did you get a homogeneous equation with $\lambda=1,2$? I will see if I can figure out a particular solution for the damping.

or I may be off line entirely. We have not covered the variation of parameters method in detail.

i have no problem using method of undetermined coefficients to solve this one... but somewhere I keep making mistake when I use variation... the answer should contain e^(x) and e^(2x) by the way - initial problem should have e^(-x), not e(-x)... sorry

I read it that way, but I don't think I'm going to be any help on this one, sorry. We haven't covered variation of parameters enough. Hopefully someone else will be able to help you out.

thank you anyway!
