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. Newton- Raphson Method of Solving a Nonlinear Equation After reading this chapter, you should be able to: 1. derive the Newton- Raphson method formula, 2. develop the algorithm of the Newton- Raphson method, 3. use the Newton- Raphson method to solve a nonlinear equation, and 4. discuss the drawbacks of the Newton- Raphson method.

It' s convergence is not guaranteed. What are the limitations of Newton' s method? 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. The Newton- Raphson method reduces to. Table 1 shows the iterated values of the root of the equation. The root starts to diverge at Iteration 6 because the previous estimate. Calculus/ Newton' s Method.

The Newton- Raphson method is a method for approximating the roots of polynomial equations of any order. In fact the method works for any equation, polynomial or not, as long as the function is differentiable in a desired interval.
