## Calculus of Variations Part 1: Establishing the Basis

Calculus of variations is an extremely useful and amazing tool in physics, math, computer science, and a variety of fields. Similar to how regular calculus is focused around functions and differentials, this field focuses on functionals and variations. A functional $\inline&space;F[y]$ takes in a function and spits out a number. The following are examples of functionals. Continue reading Calculus of Variations Part 1: Establishing the Basis
