Program for Newton Raphson Method. Given a function fx on floating number x and an initial guess for root, find root of function in interval. Here fx represents algebraic or transcendental equation. For simplicity, we have assumed that derivative of function is also provided as input. Example. Input A function of x for example x. Output The value of root is 1. OR any other value close to root. We have discussed below methods to find root in set 1 and set 2. Set 1 The Bisection Method. Set 2 The Method Of False Position. Comparison with above two methods In previous methods, we were given an interval. It is C programming FAQ code examples to Crack Interview. It has C language basic and simple source code by examples. It has arranged just like c tutorials with examples. The USGS MODFLOWNWT is a NewtonRaphson formulation for MODFLOW2005 to improve solution of unconfined groundwaterflow problems.

Fast inverse square root, sometimes referred to as Fast InvSqrt or by the hexadecimal constant 0x5F3759DF, is an algorithm that estimates 1 x, the reciprocal.

NewtonIter.png' alt='C Program For Newton Raphson Method' title='C Program For Newton Raphson Method' />Here we are required an initial guess value of root. The previous two methods are guaranteed to converge, Newton Rahhson may not converge in some cases. Newton Raphson method requires derivative. Some functions may be difficult toimpossible to differentiate. For many problems, Newton Raphson method converges faster than the above two methods. Also, it can identify repeated roots, since it does not look for changes in the sign of fx explicitly. The formula Starting from initial guess x. Newton Raphson method uses below formula to find next value of x, i. Algorithm Input initial x, funcx, deriv. FuncxOutput Root of FuncCompute values of funcx and deriv. Funcx for given initial x.

Raphsonx. 0. The value of root is 1. How does this workThe idea is to draw a line tangent to fx at point x. The point where the tangent line crosses the x axis should be a better estimate of the root than x. Call this point x. Calculate fx. 2, and draw a line tangent at x. We know that slope of line from x. By finding this point x. We have to keep on repeating the above step till we we get really close to. Alternate Explanation using Taylors Series. Let x. 1 be the initial guess. We can write x. 2 as below. Here h would be a small value that can be positive or negative. According to Taylors Series. Since we are looking for root of function, fxn1 0. Now since h is small, h would be very small. So if we ignore higher order terms, we get. Substituting this value of h xn1 xn from equation 1 we get. Notes We generally used this method to improve the result obtained by either bisection method or method of false position. Babylonian method for square root is derived from the Newton Raphson method.
