+Variational Calculus is a branch of [Calculus](/wiki/calculus) concerned with optimizing [Functional](/wiki/functional)s, which are mappings from a set of functions to the real numbers. It seeks to find functions that minimize or maximize certain integrals, often representing quantities like action or energy. This field explores entire paths or curves, rather than single points, to determine optimal configurations.
