Calculus of variations From LoveToKnow 1911 CALCULUS OF VARIATIONS, in mathematics . The calculus of variations arose from the attempts that were made by Origin mathematicians in the 17th century to solve problems of the of which the following are typical examples. (i) It Calculus. is required to determine the form of a chain of given length, hanging from two fixed points, by the condition that its centre of gravity must be as low as possible. This problem of the catenary was attempted without success by Galileo Galilei (1638). (ii) The resistance of a medium to the motion of a body being assumed to be a normal pressure, proportional to the square of the cosine of the angle between the normal to the surface and the direction of motion, it is required to determine the meridian curve of a surface of revolution, about an axis in the direction of motion, so that the resistance shall be the least possible. This problem of the solid of least resistance was solved by Sir Isaac Newton (1687). (iii) It is required to find a curve joining two fixed points, so that the time of descent along this curve from the higher point to the lower may be less than the time along any other curve. This problem of the brachistochrone was proposed by John (Johann) Bernoulli The contributions of the Greek geometry to the subject consist of a few theorems discovered by one Zenodorus, of whom little

Calculus of variations From Wikipedia, the free encyclopedia Jump to: navigation search Calculus of variations is a field of mathematics that deals with extremizing functionals , as opposed to ordinary calculus which deals with functions . A functional is usually a mapping from a set of functions to the real numbers. Functionals are often formed as definite integrals involving unknown functions and their derivatives. The interest is in extremal functions that make the functional attain a maximum or minimum value – or stationary functions – those where the rate of change of the functional is precisely zero. Perhaps the simplest example of such a problem is to find the curve of shortest length, or geodesic , connecting two points. If there are no constraints, the solution is obviously a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics . A related problem is posed by Fermat's principle : light follows the path of shortest optical length connecting two points, where the optical length depends upon the material of the medium. One corresponding concept in

Continuum mechanics/Calculus of variations From Wikiversity Continuum mechanics Jump to: navigation search Ideas from the calculus of variations are commonly found in papers dealing with the finite element method. This handout discusses some of the basic notations and concepts of variational calculus. Most of the examples are from Variational Methods in Mechanics by T. Mura and T. Koya, Oxford University Press, 1992. The calculus of variations is a sort of generalization of the calculus that you all know. The goal of variational calculus is to find the curve or surface that minimizes a given function. This function is usually a function of other functions and is also called a functional Contents Maxima and minima of functions The unconstrained problem. The constrained problem - Lagrange multipliers. Lagrange multiplier method. ... edit Maxima and minima of functions The calculus of variations extends the ideas of maxima and minima of functions to functionals. For a function of one variable f x , the minimum occurs at some point x min . For a functional, instead of a point minimum, we think in terms of a function that minimizes the functional. Thus, for a functional
