Title: Lecture 8: The Newton Method
Course: Numerical Analysis > Section: Module 4: Roots of Non Linear Functions

The Newton-Raphson methods, also called the Newton Methods, are a powerful technique for finding roots of non-linear functions numerically. Like They are based on the on the first order Taylor’ expansion of functions. The Newton Method, properly used, usually converges much more rapidly that the bisection, secant and regula falsi method.

In this lecture we will derive and use the Newton method for functions of one variable as well as for functions with more than one independent variable also called multivariate functions.
