I seem to have left out some of the "goodies" of the problem.

* The pendulum has 2 degrees of freedom.
* The driving force is a linear driving force applied at the pivot.
Imagine a simple pendulum tied to the blade of a sabre saw with
adjustable frequency. (The saw blade in this case oscillates oscillates
horizontally.)

Fun, eh?
