Derivative Of A Function Calculator

Computes the nth moment mean of a function (needs more implentation).m = moment(x, y, n)m = nth moment of yx = domainy = datan = nth moment == 1 by defaultm = int(x^n * y) / int(y)where int is integral over all x integral is calculated using trapezium rule

This scripts shows you how to obtain the name of a method or a function from within the running method/function.

A recursive function to get permutation of a list script allows you to make permutation on a list of objects. The script does not work on repeated items in the list.

In functional programming, currying is a way to bind arguments with a function and wait for the rest of the arguments to show up later. You "curry in" the first few parameters to a function, giving you a function that takes subsequent parameters as input and calls the original with all of those...
