Web13 de abr. de 2024 · From calculus, we know that the result of application of the derivative operator on a function is its derivative: Df(x) = f (x) = df dx or, if independent variable is t, Dy(t) = dy dt = ˙y. We also know that the derivative operator and one of its inverses, D − 1 = ∫, are both linear operators.
