The Calculus of Variations - University of Minnesota
The calculus of variations is a field of mathematics concerned with minimizing (or maximizing) functionals (that is, real-valued functions whose inputs are functions) The calculus of variations has a wide range of applications in physics, engineering, applied and pure mathematics, and is intimately connected to partial differential equations

Usually in calculus we minimize a function with respect to a single variable, or several variables 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

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 The weak form is vTATCAu = vTf for all v

Calculus of Variations 1 Functional Derivatives The fundamental equation of the calculus of variations is the Euler-Lagrange equation d dt ∂f ∂x˙ − ∂f ∂x = 0 There are several ways to derive this result, and we will cover three of the most common approaches Our first method I think gives the most intuitive
The Calculus of Variations - University of California, Davis
The Calculus of Variations The variational principles of mechanics are rmly rooted in the soil of that great century of Liberalism which starts with Descartes and ends with the French Revolution and which has witnessed the lives of Leibniz, Spinoza, Goethe, and Johann Sebastian Bach It is the only period of cosmic thinking in the entire

5 3 Examples from the Calculus of Variations Here we present three useful examples of variational calculus as applied to problems in mathematics and physics 5 3 1 Example 1 : minimal surface of revolution Consider a surface formed by rotating the function y(x) about the x-axis The area is then A y(x) = Zx2 x1 dx2πy s 1+ dy dx 2, (5 23)
