2021-4-13 · Calculus of variations, branch of mathematics concerned with the problem of finding a function for which the value of a certain integral is either the largest or the smallest possible. Many problems of this kind are easy to state, but their solutions commonly involve difficult procedures of the differential calculus and differential equations .

I[y] = Z b a dxF x;y(x);y0(x) (16:5) The speci c Fvaries from problem to problem, but the preceding examples all have Calculus of Variations 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). Usually in calculus we minimize a function with respect to a single variable, or several variables. Here the potential energy is a function of a function, equivalent to an infinite number of variables, and our problem is to minimize it with respect to arbitrary small variations of that function.

2019-1-1 · Calculus of variations is a field of mathematical analysis that deals with maximizing or minimizing functionals, which are mappings from a set of functions to the real numbers.Functionals are often expressed as definite integrals involving functions and their derivatives.The interest is in extremal functions that make the functional attain a maximum or minimum value – or stationary functions
calculus of variations are prescribed by boundary value problems involving certain types of differential equations, known as the associated Euler–Lagrange equations. The math- calculus of variations dips.

In calculus of variations the basic problem is to find a function y for which the functional I(y) is maximum or minimum. We call such functions as extremizing functions and the value of the functional at the extremizing function as extremum. Consider the extremization problem Extremize y I(y) = Zx 2 x1 F(x,y,y′)dx subject to the end conditions y(x 1) = y In mathematics, specifically in the calculus of variations, a variation δf of a function f can be concentrated on an arbitrarily small interval, but not a single point. Accordingly, the necessary condition of extremum ( functional derivative equal zero) appears in a weak formulation (variational form) integrated with an arbitrary function δf . 4.
