Formulation And Validation Of First Order Lagrangian

Authors: Eric Su

An unproven lagrangian generates erroneous theory. The unknown lagrangian can be validated with Hamiltonian. The invalid lagrangian can be formulated into a valid lagrangian with a three-phase process based on Euler-Lagrange equation and conservation law. The formulation process modifies the lagrangian with system invariant. The process is superior to the popular trial-and-error approach.
