Abstract

In the expression for a differential equation the derivative operator \(D \equiv d/dx\) and powers of this operator, \(D^{k}, \, (k = 1, 2,\ldots )\), operate on a function y(x). We consider the corresponding operator, \(\Delta \), for difference equations and derive expressions for \(\Delta ^{k}\) operating on the product or the ratio of two functions and compare them to the corresponding expressions for the derivative operator.
