I'm not sure exactly how to solve this ODE. (dx^2)/(dt^2) + (w^2)x = Fsinwt, where x(0) = 0 and X'(0) = 0.
What I've got so far is:
x'' + w^2x = Fsinwt --> x(homogenous) = Acoswt + Bsinwt
I know I have to find a particular solution but I keep getting zero as a result which I know won't solve the ODE.
Also, I know that the answer is (F/2w^2)sinwt - (F/2w)tcoswt
