What is Lagrange Multipliers in Mechanics about?

This document discusses Lagrange multipliers, a method for handling constraints in variational problems. It introduces the concept of adding constraint equations to the Lagrangian with undetermined multipliers to eliminate variations that violate constraints. Setting the variation of the augmented action to zero yields the Lagrange equations and determines the constraint forces as combinations of the multipliers.
