The equations describing the extremality condition of a functional are frequently low-order ordinary and/or partial differential equations and their solutions. For example, for a pendulum: Frechet derivative of Integrate[x'[t]^2/2 – Cos[x[t]], {t, -inf, inf}] wrt x[tau] .

Find, customize, share, and embed free differential equations Wolfram|Alpha Widgets.

NDSolve[eqns, u, {x, xmin, xmax}] finds a numerical solution to the ordinary differential equations eqns for the function u with the independent variable x in the range xmin to xmax. NDSolve[eqns, u, {x, xmin, xmax}, {y, ymin, ymax}] solves the partial differential equations eqns over a rectangular region.
