The Newton-Raphson Method 1 Introduction The Newton-Raphson method, or Newton Method, is a powerful technique for solving equations numerically. Like so much of the di erential calculus, it is based on the simple idea of linear approximation. The Newton Method, properly used, usually homes in on a root with devastating e ciency.

faster than most iterative methods we can design. ▻ Newton's method is also called Newton-. Raphson method ... Newton's method is a fixed point iteration.

Newton-Raphson Method If f(x) has a simple root near x n then a closer estimate to the root is x n+1 where x n+1 = x n − f(x n) f0(x n) This is the Newton-Raphson iterative formula. The iteration is begun with an initial estimate of the root, x 0, and continued to find x 1,x 2,... until a suitably accurate estimate of the position of the ...

0.1 Newton Raphson Method The Newton Raphson method is for solving equations of the form f(x) = 0. We make an initial guess for the root we are trying to find, and we call this initial guess x 0. The sequence x 0,x 1,x 2,x 3,... generated in the manner described below should con-verge to the exact root.

2.1 The Newton-Raphson Iteration Let x 0 be a good estimate of rand let r= x 0 + h.Sincethetruerootisr, and h= r−x 0,thenumberhmeasures how far the estimate x 0 is from the truth. Since his ‘small,’ we can use the linear (tangent line) approximation to conclude that 0=f(r)=f(x 0 + h) ˇf(x 0)+hf0(x 0); and therefore, unless f0(x 0)iscloseto0, hˇ− f(x 0) f0(x 0) It …
