Our derivation is a modification of the finite difference technique employed by Euler in his path-breaking 1744 work, “The method of finding plane curves that show some property of maximum and minimum.” Derivation of Euler--Lagrange equations We derive the Euler–Lagrange equations from d’Alembert’s Principle. Suppose that the system is described by generalized coordinates q . Warning 2 Y satisfying the Euler-Lagrange equation is a necessary, but not sufficient, condition for I(Y) to be an extremum.

It was a hard struggle, and in the end we obtained three versions of an equation which at present look quite useless. But from this point, things become easier and we rapidly see how to use the equations and find that they are indeed very useful.

The Euler-Lagrange equations are derived by finding the critical points of the action $$\mathcal A(\gamma)=\int_{\gamma(t)}g_{\gamma(t)}(\gamma^\prime(t),\gamma^\prime(t))dt.$$ A standard fact from Riemannian geometry is that the critical points of this functional (the length functional) are geodesics.
