Damped, driven oscillations

This is the final post in a four-part series on vibrating systems. The first three parts were free, undamped vibrations free, damped vibrations driven, undamped vibrations and now we consider driven, damped vibrations. We are looking at the equation m u'' + γ u' + k u = F cos ωt where all coefficients are positive. As in the previous post, we [...]
