MathWorld. Calculus of variations.

It was instrumental in formulating variational principles of mechanics and physics and continues to supply insight into the relationship between these principles and their Euler-Lagrange systems of differential equations. carries ordinary calculus into the calculus of variations. We do it in several steps: 1. One-dimensional problems P(u) = R F(u;u0)dx, not necessarily quadratic 2. Constraints, not necessarily linear, with their Lagrange multipliers 3. Two-dimensional problems P(u) = RR F(u;ux;uy)dxdy 4. Time-dependent equations in which u0 = du=dt.

A branch of mathematics that is a sort of generalization of calculus. Calculus of variations seeks to find the path, curve, surface, etc., for which a given function has a stationary value (which, in physical problems, is usually a minimum or maximum ). In science and especially in mathematical studies, a variational principle is one that enables a problem to be solved using calculus of variations, which concerns finding such functions which optimize the values of quantities that depend upon those functions.

### Application of the variational calculus to wetting phenomena

We’ve seen how Whewell solved the problem of the equilibrium shape of chain hanging between two places, by finding how the forces on a length of chain, the tension at the two ends and its weight, balanced. 3 Calculus of variations in Machine Learning The practical example which will be investigated is the problem of lower bounding the marginal likelihood using a variational approach. What is the Calculus of Variations “Calculus of variations seeks to find the path, curve, surface, etc., for which a given function has a stationary value (which, in physical problems, is usually a minimum or maximum).” (MathWorld Website) Variational calculus had its beginnings in 1696 with John Bernoulli Applicable in Physics Variational calculus is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find extrema of functionals: mappings from a set of functions to the real numbers. The archetype application in physics is Lagrangian mechanics, seeking extrema of action functionals.

Note that variational calculus has been applied to an extensively large number of problems, theories, and formulations most of which could be reexamined in the light of fractional variational calculus. Thus, the above work has opened significant opportunities for many new research.
