  • The brachistochrone curve that gives the minimum travel time is determined by using the calculus of variations to find the best compromise between the shortest path – i.e., a straight slope – and the path that gives the maximum initial acceleration, i.e., a vertical drop followed by a short bend followed by a horizontal path.
