The Newton iteration method (Newton's method) is also called the Newton Ravson (Raphson) method (Newton-Raphson method). It is a method proposed by Newton in seventeenth Century to approximate the equation in the real number field and the complex field. Most equations do not exist formula, so the accurate root is very difficult, even impossible, to find the approximate root is particularly important. The method uses the first few of the Taylor series of the function f (x) to find the root of the equation f (x) = 0. Newton iterative method is one of the important methods to solve the equation, its biggest advantage is in equation f (x) = 0 has quadratic convergence near the single, and the method can also be used for the root, complex equations, the linear convergence, but through some methods into super linear convergence. In addition, this method is widely used in computer programming
