👉 The term "post-derivative" refers to a derivative function that is not defined at one point, but rather at all points in its domain. In other words, it can be evaluated at any point in its domain without necessarily being continuous or differentiable there. For example, the derivative of a function f(x) = x^3 + 2x - 1 with respect to x is given by: f'(x) = 3x^2 + 2 However,
