Newton iterative method (the Newton's method), also known as the Newton-Raphson method (the Newton-Raphson method), which was introduced by Newton in the 17th century in the Reals and complex field approximation method for solving equations. Most equations formula of root does not exist, so the exact root is very difficult, if not impossible, to find the approximate root of equation is especially important. Method uses a function f (x) Taylor in front of a few to find the equation f (x) = 0. Newton-Raphson method is the root of equation is one important way, is its biggest advantage of the equation f (x) = 0 root around with quadratic convergence,
