Title: Module 2: Finite Difference Operators and Formulas
Course: Numerical Analysis

This module has two lectures. In Lecture Three, we define several finite difference operators. We learn how to construct a finite difference operator table. We prove identities involving finite difference operators.
In Lecture Four, we study several formulas for numerical interpolation which involve finite difference operators. These formulas include the Newton Forward Difference formula and the Newton Backward Difference formula. We also study formulas involving the central difference and the averaging operator.
