WebApr 11, 2024 · Such an equation will be useful because it can allow us to determine specific formulas for x(t). To derive the Euler-Lagrange equation, introduce some function η(t) that satisfies η(a) = η(b) = 0 and let ε be a real number variable that we can dial up and down. Then define the function X(t) as follows: X(t) = x(t) + ε η(t).
