Calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers.

A branch of mathematics that is a sort of generalization of calculus calculus of variations seeks to find the path, curve, surface, etc, for which a given function has a stationary value (which, in physical problems, is usually a minimum or maximum) mathematically, this involves finding. Calculus of variations and partial differential equations attracts and collects many of the important top-quality contributions to this field of research, and stresses the interactions between analysts, geometers, and physicists. In this lecture we discuss the application of calculus of variations we consider the motion of a particle of mass m moving in a force field and show that the motion is such that the integral of th integral equations.
