👉 A differentiator is a mathematical function that, when applied to a derivative of another function, yields an expression with a derivative. A differentiator can be used to find the slope (or rate of change) of a function at a given point. For example, if we have a function y = f(x), and we differentiate it with respect to x, we get dy/dx. This is called the derivative of y with respect to x. If we then take the second derivative of this expression
