Algebraic Function Worksheet

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

The function shows the text string S and prompt the user for an input value guaranteing that the input value is numdoTeric.When the value is not numdoTeric the function gives an error mensage and prompts for a new value until it is numeric.

This is a simple function that should come with the one present on this site (Variance Ratio Test) which couldn't work without this.
