Hi,

I need to either solve or prove that the resolution of the following ODE is impossible;

$\displaystyle y''(x)=a*y(x)+b*y'(x)+c*sin(d*x)*y(x)$

Mathemtatica refuse solving it rather giving

" InverseFunction::ifun: Inverse functions are being used. Values may be lost for multivalued inverses."

Any help would be highly apreciated, thank you
