The 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. Functionals are often expressed as definite integrals involving functions and their derivatives.

5.3.1 Example 1 : minimal surface of revolution Consider a surface formed by rotating the function y(x) about the x-axis. The area is then A y(x) = Zx2 x1 dx2πy s 1+ dy dx 2, (5.23) This method of solving the problem is called the calculus of variations: in ordinary calculus, we make an infinitesimal change in a variable, and compute the corresponding change in a function, and if it’s zero to leading order in the small change, we’re at an extreme value. Introduction to variational calculus: Lecture notes 1 Edwin Langmann Mathematical Physics, KTH Physics, AlbaNova, SE-106 91 Stockholm, Sweden Abstract I give an informal summary of variational calculus (complementary to the discussion in the course book). Aims (what I hope you will get out of these notes): 2021-04-13 · 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 ).

All this is to set the stage calculus of variations, branch of mathematics mathematics, deductive study of numbers, geometry, and various abstract constructs, or structures; the latter often "abstract" the features common to several models derived from the empirical, or applied, sciences, although many emerge from purely mathematical or logical calculus of variations has been intimately connected with the theory of di eren-tial equations; in particular, the theory of boundary value problems. Sometimes a variational problem leads to a di erential equation that can be solved, and this gives the desired optimal solution.

Maxima and Minima Let X and Y be two arbitrary sets and f : X → Y be a well-deﬁned function having domain X and range Y. Calculus of Variations 1 Functional Derivatives The fundamental equation of the calculus of variations is the Euler-Lagrange equation d dt ∂f ∂x˙ − ∂f ∂x = 0. There are several ways to derive this result, and we will cover three of the most common approaches. Our ﬁrst method I think gives the most intuitive functions for the variational problem. So, the passage from ﬁnite to inﬁnite dimensional nonlinear systems mirrors the transition from linear algebraic systems to boundary value problems. 2. ExamplesofVariationalProblems.
