Using the same approach as with Fixed-point Iteration, we can determine the convergence rate of Newton’s Method applied to the equation f(x) = 0, where we assume that f is continuously di erentiable near the exact solution x, and that f 00 exists near x.

FIXED POINT ITERATION The idea of the xed point iteration methods is to rst reformulate a equation to an equivalent xed point problem: f(x) = 0 x = g(x) and then to use the iteration: with an initial guess x 0 chosen, compute a sequence x n+1 = g(x n); n 0 in the hope that x n! . There are in nite many ways to introduce an equivalent xed point

Fixed point iterations In the previous class we started to look at sequences generated by iterated maps: x k+1 = φ(x k), where x 0 is given. A fixed point of a map φ is a number p for which φ(p) = p. If a sequence generated by x k+1 = φ(x k) converges, then its limit must be a fixed point of φ.

Fixed-point Iteration A nonlinear equation of the form f(x) = 0 can be rewritten to obtain an equation of the form g(x) = x; in which case the solution is a xed point of the function g. This formulation of the original problem f(x) = 0 will leads to a simple solution method known as xed-point iteration. Before we describe
