This made as little sense to me as it did when I was talking the Finite Element Methods class during graduate school.
Still don't quite understand why you can't just use Runge Kutta methods to numerically solve these problems. I became quite good at manipulating the symbols to derive variational solutions while having absolutely no idea what any of it meant.
