how do i solve this? $\displaystyle \frac{d^2y}{dx^2}+2\frac{dy}{dx}+2y=10exp(-x)sinx$ any ideas? the complementary function is$\displaystyle exp(-x)(Acosx+Bsinx)$ for this reason should the trial particular integral be erm,,,,$\displaystyle xexp(-x)(Dcosx+csinx)$???

i've basically never met an example like this and dont know what the trial yp should be?!Inhomogeneous 2nd-order differential equations
