Geodesics Suppose we have a surface specified by two parameters u and v and the vector .( )vur , The … Based on a series of lectures given by I. M. Gelfand at Moscow State University, this book actually goes considerably beyond the material presented in the lectures. The aim is to give a treatment of the elements of the calculus of variations in a form both easily understandable and sufficiently modern. Considerable attention is devoted to physical applications of variational methods, e.g Calculus of Variations.

5.3 Examples from the Calculus of Variations Here we present three useful examples of variational calculus as applied to problems in mathematics and physics. 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) In this video, I introduce the subject of Variational Calculus/Calculus of Variations.

The main body of Chapter 2 consists of well known results concerning necessary or suﬃcient criteria for local minimizers, including Lagrange mul-tiplier rules, of real functions deﬁned on a Euclidean n-space. Chapter 3 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.

### A word of advice for someone new to the calculus of variations: keep in mind that since this book is an older text, it lacks some modern context. For example, the variational derivative of a functional is just the Frechet derivative applied to the infinite-dimensional vector space of admissible variations.

## Calculus of Variations It is a well-known fact, first enunciated by Archimedes, that the shortest distance between two points in a plane is a straight-line. However, suppose that we wish to demonstrate this result from first principles.

Remark To go from the strong form to the weak form, multiply by v and integrate. For matrices the strong form is ATCAu = f. The weak form is vTATCAu = vTf for all v.
