## 본문내용

Find root using Newton-Raphson method and consider convergence and principle of Newton-Raphson method.

Introduction
There are several parts of finding root method, closed method and open method. The Closed method consists of graphical method, bisection method, and false position method. And the open method consists of fixed-point iteration, Newton-raphson method, and secant method. Newton-raphson method is considered in report.

Experimental Results
Root of initial guess 4.2 : 0.475, 26 times iteration
Root of initial guess 4.43 : 0.475, 10 times iteration

Aerror : approximation percent relative error
AError= (current approximation-previous approoxiamtion)/(current approximation)
Terror : The true percent relative error.
TError=numerical value-analysis value
