1. The problem statement, all variables and given/known data y = c1e3xcos(2x)+c2e3xsin(2x)+c3+c4x 2. Relevant equations Differential Equations. 3. The attempt at a solution I am having trouble what the roots are for the c3, and c4 parts. I know they are a repeated root, but is it just k= 0? It seems like it would work, but I am not sure.
