Chapter 9: Numerical Differentiation, and Non-Differentiable Functions

Introduction

We discuss how you can numerically differentiate a function with high accuracy with little effort. One setup can allow you to do so for any function you can enter by doing so once, and doing some copying.We then indicate how one can estimate the derivative of your function at say a hundred points and graph it on your spreadsheet, and also testing the accuracy of your estimates.
