The Newton-Raphson Method 1 Introduction The Newton-Raphson method, or Newton Method, is a powerful technique for solving equations numerically. Like so much of the di erential calculus, it is based on the simple idea of linear approximation. The Newton Method, properly used, usually homes in on a root with devastating e ciency.

the root. ▻ In the previous example 2 steps of the bisection method would have given the interval [3.5,4.25].

An initial estimate of the root is found (for example by drawing a graph of the function). This estimate is then improved using a technique known as the. Newton ...

An initial estimate of the root is found (for example by drawing a graph of the function). This estimate is then improved using a technique known as the Newton-Raphson method, which is based upon a knowledge of the tangent to the curve near the root. It is an “iterative” method in that it can be used repeatedly to continually improve the ...

0.1 Newton Raphson Method The Newton Raphson method is for solving equations of the form f(x) = 0. We make an initial guess for the root we are trying to find, and we call this initial guess x 0. The sequence x 0,x 1,x 2,x 3,... generated in the manner described below should con-verge to the exact root.
