After that, going from two to three was just more algebra and more complicated pictures. The first part starts with the statement of the fundamental variational problem and its solution via the Euler-Lagrange equation. An excellent introduction to the calculus of variations with application to various problems of physics. The calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers. Exercises throughout.

Yes, I took undergraduate real analysis and I'm now taking ODEs however, a self-contained book with some revision of the necessary material would be good. Also during this time a popular book for the physics graduate students was Weinstock's Calculus of Variations: With Applications to Physics and Engineering.

It has many advantages: It is cheap so if you buy it and don't like it, it's not a big deal ; It is written by good mathematicians, that are broad enough to see connections with many different areas; It has useful exercises, and they're reasonable and with an eye on applications; It has an appendix on Optimal Control.

I'm a tenth grader, so graduate texts are not very comfortable to learn from I could, but I'd have to devote too much time.. Any excellent undergrad text source or pdf would be appreciated.

### Gelfand,Fomin - Calculus Of Variations.pdf

The calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals , to find maxima and minima of functionals: mappings from a set of functions to the real numbers. Functions that maximize or minimize functionals may be found using the Euler—Lagrange equation of the calculus of variations. A simple example of such a problem is to find the curve of shortest length connecting two points. If there are no constraints, the solution is a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics.
