👉 In mathematics, a "drisk" is a type of function that takes an argument and returns its derivative. It is often used in optimization problems to find the best possible value for a variable based on certain constraints or data points. A Driskel (or even more generally a "derivative of a function") is a particular kind of function that can be seen as a special case of the Taylor series expansion of a function, where each term can be considered as being a derivative of some other
