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.

The branch of mathematics in which one studies methods for obtaining extrema of functionals which depend on the choice of one or several functions subject to constraints of various kinds (phase, differential, integral, etc.) imposed on these functions. 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. 2009-9-2 · 2 1 Calculus of variations 1.2.1 The functional derivative We restrict ourselves to expressions of the form J[y]= x 2 x1 f(x,y,y,y,···y(n))dx, (1.1) where f depends on the value of y(x) and only finitely many of its derivatives.

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 .

For matrices the strong form is ATCAu = f.
