Homework Statement
[tex] 22e^{2t}=y''+8y'-95 [/tex]
Homework Equations
The Attempt at a Solution
I've been reading a textbook on this and think that I should use "method of undetermined coefficients" I know [tex] r(x)=ke^{\gamma*x}[/tex] so [tex]y_p(x)=Ce^{\gamma*x}[/tex]
The trouble is after reading the entire chapter I don't know what to do with that? I'm using Advanced Engineering Mathematics by Kreyszig and it is the worst textbook I have ever used there is huge gaps in methods and no easy to understand descriptions of the maths! Anyone know of any good textbooks for DE's??
Thanks for any help
