A particle of mass m is subject to a spring force, -kx, and also a driving force, Fa cos wat. But there is no damping force. Find the particular solution for x(t) by guessing x(t) = A cos wat + B sin wat. If you write this in the form C cos(wat - ), where C > 0, what are C and o? Be careful about the phase (there are two cases to consider)
