Homework Statement
y'' + y' + y = 1 + x + x2
Homework Equations
y = Ʃ CN*xN N starts at 0
y' = Ʃ N*CN*x(N-1) N starts at 1
y'' = Ʃ N*(N-1)*CN*x(N-2) N starts at 2
3. The Attempt at a Solution [/]
I know how solve the equations using series when the equation would equal to 0. My main question about using series on a non-homogeneous differential equation is whether or not the varialbes on the right side have the Cx coefficients? Or would they be paired up with the x, x2, etc? I think I need some quick clarification on this.
Thanks!
