Calculus of variations

Over half term I got interested in the brachistochrone problem (which was first introduced to me just before the summer) and ended up looking much further into the calculus of variations, which provides one of several solutions to the problem. Here’s my write-up which is intended as an introduction to the topic aimed at a further mathematician in year 13 or similar.
