Web26 de fev. de 2024 · A variation of a functional is the small change in a functional's value due to a small change in the functional's input. It's the analogous concept to a differential for regular calculus. We've already seen an example of a variation in Equation 5, which is the first variation of the functional F: δF(y, η) = ∫ δF δy(x)η(x)dx.
