Can anyone give me a hand with this, cause I'm stumped and can't remember exactly how to go about solving this.(adsbygoogle = window.adsbygoogle || []).push({});

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

it's from physics but the principles are just maths.
