(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The motion of an undamped mass-spring system is described by the differential equation 2x" + 36x = sin(wt)

a) For what values of w will the system exhibit resonance?

b) Use the method of undertermined coefficients to find a particular solution in the case where w is not the resonant frequency.

I know I have to use y = Asin(wt) but I am stuck after that.
