How to derive lagrangian equation

WebThe derivation of the one-dimensional Euler–Lagrange equation is one of the classic proofs in mathematics. It relies on the fundamental lemma of calculus of variations . We wish to find a function f {\displaystyle f} which satisfies the boundary conditions f ( a ) = A {\displaystyle f(a)=A} , f ( b ) = B {\displaystyle f(b)=B} , and which ...
