WebThe Brachistochrone Problem Brachistochrone – Derived from two Greek words brachistos meaning shortest chronos meaning time The problem – Find the curve that will allow a particle to fall under the action of gravity in minimum time. Led to the field of variational calculus First posed by John Bernoulli in 1696 – Solved by him and others WebThe brachistochrone is an extremal of this functional, and so it satisfies the Euler-Lagrange equation. = 0, y (0) = 0, y ( h) = a . Integrating this, we get. = c. where c is a constant, and rearranging. y' = = , with α = . We can integrate this equation using the substitution x = αsin2θ to obtain.
