## What is Newton's Method?

Newton-Raphson method or Newton method is a **numerical analysis method** that finds a better approximation of a higher degree polynomial function's root with each iteration. It is known as the Newton's Method or the Newton-Raphson method.

In this method, we use repeat calculations ( repeated calculations are known as n iterations where n=0,1,2,3….) toward a solution till the desired result is not achieved that has a better accuracy rate.

Additionally, if you are seeking an alternative root-finding method, the bisection calculator offers a straightforward approach to approximating roots of functions. By leveraging this calculator, you can efficiently solve root-finding problems and gain insights into the behavior of functions.

## Formula Behind Newton Raphson Method Calculator

Let the function f(x) and derivative of a function be f’(x) at a specific number n. The **formula** behind Newton's Method calculator is as follows:

$$ f(x_n + 1) \;=\; x_n - \frac{f(x_n)}{f’(x_n)} $$

- f′(x) represents the first-order derivative at x.
- x0 is the initial value for f(x) and f’(x)
- f(x0) is the initial value of the function
- n is the number of roots where n = 0,1,2, 3, …

This formula utilizes the tangent line to the function at the current approximation point xn to iteratively refine the approximation until a satisfactory solution is obtained

Moreover, if you are looking to evaluate indeterminate limits and understand the application of L'Hopital's Rule in calculus, you can use our l hospital rule calculator. By utilizing this calculator, you can efficiently solve limit problems and gain insights into the behavior of functions near points of indeterminacy.

## Computation Process Used in Newton Raphson Calculator

Newton method calculator uses the easiest way to find the solution to get the estimated value of Newton Rapson method problem because it has advanced features to solve these complicated numeric problems.

When you **add the input value** function in the Newton-Rapson method calculator then Newtons method calculator will check the behavior of the given function. After checking the nature of the function f(x) it will take the derivative of function f’(x).

Then newton's method approximation calculator adds the f(x), f’(x), and x0 values in the Newton Rapson method formula as a first iteration to get the value of x1. After getting the value of x1 then again it applies the Newton formula but replaces the root from x0 to x1 to get the next root x2.

In this way, Newton's method calculator can **add the next iteration** in Newton's formula and get the new root for the given function. This process will go on until you get the solution of your required root value as shown in the below example for more clarity.

## Practical Example of Newton's Method Problem

Let's understand an example of a Newton method problem to know how to solve such problems manually. Although Newton Raphson calculator can solve problems precisely but its also important to understand each step so an example is given,

### Example:

Approximate a root of the following in the interval [1,2] using Newton’s method. Let x0 = 2 and determine x1, x2, … , x5.

**Solution:**

We see that f has one root over the interval [1,2], since

$$ f(x) \;=\; x^3 - 3x +1, \;the\;derivative\;is\; f’(x) \;=\; 3x^2 - 3 $$

$$ x_1 \;=\; x_0 - \frac{f(x_0)}{f’(x_0)} \;=\; 2 - \frac{f(2)}{f’(2)} \;=\; 2 - \frac{3}{9} \approx 1.666666667 $$

To determine the next approximation, x^{2},

$$ x_2 \;=\; x_1 - \frac{f(x_1)}{f’(x_1)} \approx 1.548611111 $$

Continue with the same sequence,

$$ x_1 \approx 1.666666667 $$

$$ x_2 \approx 1.548611111 $$

$$ x_3 \approx 1.532390162 $$

$$ x_4 \approx 1.532088989 $$

$$ x_5 \approx 1.532088886 $$

$$ x_6 \approx 1.532088886 $$
