Something that covers calculus of variations, Euler-Legrange equation, etc. I first covered this in Classical Mechanics but don't remember the textbook. The Feynman Lectures of Physics [2] probably covers it, but I don't know for certain.

Indeed it does:

Caltech is fantastic. They even have the old-form domain name there in your links, similar to Stanford CS department which is also exceptional in the nomenclature, but grandfathered in.
