This document outlines a presentation on using Newton's method and Visual Basic for Applications (VBA) in Excel to find the root of a function. It begins with an example of using Newton's method by hand to find the root of f(x)=x^2-2 with an initial guess of -1. It then shows how to write a VBA function to perform the iterations of Newton's method automatically using a loop. The presentation teaches exercises where attendees define a VBA function to return the estimated root after one iteration, and then modify it to run Newton's method for 4 iterations using a loop. The goal is to introduce numerical methods and programming in VBA to approximate roots of functions.
