PHYS2113 2023 Video 4 -- Calculus of Variations (Part 2)

This lecture is the first in a series on Lagrangian mechanics looking at the calculus of variations. This second half we show mathematically that the shortest distance between two points is a straight line, look at Fermat's principle, and solve the classic Brachistochrone problem.
