Introduction
The Newton-Raphson method, named after Isaac Newton (1671) and Joseph Raphson (1690), is a method for finding successively better approximations to the roots of a real-valued function. But both Newton and Raphson viewed this method purely as an algebraic method and restricted its use to polynomials. In 1740, Thomas Simpson described it as an iterative method for solving general nonlinear equations using fluxional calculus (i.e., derivatives), essentially giving the modern description of the method. Historical facts are given by T. Ypma [ 40 ], H. Goldstine [ 21 ], and J. Ezquerro et al. [ 17 ]. Recent developments of this method include alpha-theory, underdetermined or overdetermined systems, and equations defined on Lie groups or on Riemannian manifolds.
Let \(f : U \subset E \rightarrow F\) be the equation to be solved where E and F are two real or complex Banach spaces and where U is open in E and f ∈ C 1 ( U ). If x ∈ E is an approximation of a zero of f ,...

Newton Raphson Method
The paper is about Newton Raphson Method which is all-inclusive to solve the non-square and non-linear problems. The study also aims to comparing the rate of performance, rate of convergence of Bisection method, root findings of the Newton meted and Secant method. It also represents a new approach of calculation using nonlinear equation and this will be similar to Newton Raphson simple method and inverse Jacobian matrix will be used for the iteration process and this will be further used for distributed power load flow calculation and will also be helpful in some of the applications. The paper also discusses the difference between the use of built in derivative function and self-derivative function in solving non-linear equation in scientific calculator. The derivation Newton Raphson formula, algorithm, use and drawbacks of Newton Raphson Method have also been discussed.

There exist two widely-used numerical methods (the Gauss-Seidel: GS and the Newton-Raphson: NR) to solve this problem and therefore referred to as the GS and the NR power-flow solution methods, respectively. Although the standard Newton-Raphson (NR) method is the most powerful algorithm for the power flow analysis in electric power systems, the calculation of Jacobian matrix derivatives involves high computational time. The proposed method presents a simplified Newton-Raphson power flow solution method to simplify overall equation complexity and computation time. The simplified Newton-Raphson method employs nonlinear current mismatch equations instead of the commonly used power mismatch equations. Numerical results are presented with 5-bus test system and IEEE 30-bus test system and compared with standards NR method.

Abstract:This paper used the Newton-type Methodfor estimating a single root of nonlinear equations. This method is iterative method and also known as one of the open methods. Open method are fast converging method as compared to closed method but the convergence is not guaranteed. Since open methods are fast convergence methods that is why they are widely used in Applied Mathematics. The proposed numerical technique is second order of convergence, and which is based on Newton Raphson method. The developed algorithm is compared with the well-known Newton Raphson Method and results show that our developed method is much better than the well-known method. Furthermore, examples are also give in order to give more detailed about the present work and reader will come to know that why developed method is much better as compare to well-known method.

Title: sketched newton-raphson.
Abstract: We propose a new globally convergent stochastic second order method. Our starting point is the development of a new Sketched Newton-Raphson (SNR) method for solving large scale nonlinear equations of the form $F(x)=0$ with $F:\mathbb{R}^p \rightarrow \mathbb{R}^m$. We then show how to design several stochastic second order optimization methods by re-writing the optimization problem of interest as a system of nonlinear equations and applying SNR. For instance, by applying SNR to find a stationary point of a generalized linear model (GLM), we derive completely new and scalable stochastic second order methods. We show that the resulting method is very competitive as compared to state-of-the-art variance reduced methods. Furthermore, using a variable splitting trick, we also show that the Stochastic Newton method (SNM) is a special case of SNR, and use this connection to establish the first global convergence theory of SNM. We establish the global convergence of SNR by showing that it is a variant of the stochastic gradient descent (SGD) method, and then leveraging proof techniques of SGD. As a special case, our theory also provides a new global convergence theory for the original Newton-Raphson method under strictly weaker assumptions as compared to the classic monotone convergence theory.

However, this method is limited since it diverges for the case in which polynomials only have complex roots if a real initial condition is taken.
