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 guessing it has to be shown by undetermined coefficients but I can't find the right path exactly.
