Can anyone give me a hand with this, cause I'm stumped and can't remember exactly how to go about solving this.

here's the eqn

m[d^2x/dt^2 + wsubo^2 x] = F cos wt

I'm supposed to show that x(t) = xsubo cos wt

w is the incident freq
wsubo is the resonant freq
m is mass

I'm stuck with the part of getting out ysubp, at least that's what I think I should do.

Can u solve the homogenous equation...?If so,then u can use the method of Lagrange to find a particular solution of the nonhomogenous ODE.
