• Simplified treatment of direction of pendulum

Lecture notes

A full treatment of the Foucault pendulum is rather involved, but the simplified treatment in the lecture notes provides an elementary explanation of the basic features of this surprising result, as well as practice solving coupled ODEs.

This derivation pairs well with that for linear motion in the 2-dimensional case, but if there is only time for one, do this one instead.
