Lesson Summary:

In this lesson, you will learn about Newton's Method, an algorithm for computing increasingly accurate approximations to a root of a function. The lesson takes several examples to help you understand the method better. You'll see how to use it to solve for the square root of 3, find points of intersection of two graphs, find the radius of a circular arc, and more. You'll also learn about the Newton's method theorem and quadratic convergence.

Lesson Description:

    This topic of this video is Newton’s Method. It explains how the method works and how to actually use it to approximate the root of a function. Several very different applications of Newton’s Method are shown and explained as well. The method of actually using Newton’s Method on the calculator is shown, and you can see how accurate this method is along with what constraints come with it.
