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.

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 .

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. In other words, if we The calculus of variations is a field of mathematics concerned with minimizing (or maximizing) functionals (that is, real-valued functions whose inputs are functions). calculus of variations. Its constraints are di erential equations, and Pontryagin’s maximum principle yields solutions. That is a whole world of good mathematics. Remark To go from the strong form to the weak form, multiply by v and integrate. For matrices the strong form is ATCAu = f.
