30.06.2019 · Newton Raphson Method uses to the slope of the function at some point to get closer to the root. Using equation of line y = m x0 + c we can calculate the point where it meets x axis, in a hope that the original function will meet x-axis somewhere near. We can reach the original root if we repeat the same step for the new value of x.

In numerical analysis, Newton’s method is named after Isaac Newton and Joseph Raphson. This method is to find successively better approximations to the roots (or zeroes) of a real-valued function. The method starts with a function f defined over the real numbers x, the function’s derivative f’, and an initial guess \(x_{0}\) for a root of the function f.

Solved Example. Question: Estimate the positive root of the equation x 2 – 2 = 0 by using Newton’s method. Begin with x 0 = 2 and compute x 1. Solution: Given measures are, f(x) = x 2 – 2 = 0, x 0 = 2. Newton’s method formula is: x 1 = x 0 – \(\frac{f(x_{0})}{f'(x_{0})}\) To calculate this we have to find out the first derivative f'(x) f'(x) = 2x So, at x 0 = 2, f(x 0) = 2 2 – 2 = 4 – 2 = 2

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.

Example: The Newton Raphson Method Find a root of the equation x^2-8x+11=0 to 5 decimal places using x_0=6. First we need to differentiate f(x)=x^2-8x+11: f'(x)=2x-8. Substituting this into the Newton-Raphson formula: x_{n+1}=x_n-\dfrac{x^2-8x+11}{2x-8} Starting with x_0=6: x_1=6-\dfrac{6^2-8(6)+11}{2(6)-8}=6.25

The formula will be xb=xa+(1/f'(xa)*(0-f(xa)=xa-(1/f'(xa)*(f(xa). The formula can be used to get the distance x for the root point b for which we are looking.

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. To implement it analytically we need a formula for each approximation in terms of

0.4 Possible problems with the method The Newton-Raphson method works most of the time if your initial guess is good enough. Occasionally it fails but sometimes you can make it work by changing the initial guess. Let’s try to solve x = tanx for x. In other words, we solve f(x) = 0 where f(x) = x−tanx. The recursion formula (1) becomes x n+1 ...
