Error Estimate for the Newton-Raphson Method
www-solar.mcs.st-and.ac.uk › ~alan › MT2003
Error Estimate for the Newton-Raphson Method In this section we estimate how the error varies from one iteration to the next. This gives us an idea on the speed of convergence of the method. Using the definition of absolute error in we have the following relation between the exact value of the root , the iterate and the error after iterations ,

xn+1 = xn - f (xn)/f’ (xn) what we would like is instead something showing the ratio between xn+1 and xn. One can use Taylor’s Formula and Newton’s Method to show that if r denotes the real root then the error after n+1 and n iterations compares as. | xn+1 - r | < (M/2m) | xn – r| 2. where:

Newton's Method: What Could Go Wrong?
ocw.mit.edu › courses › mathematics
If 2the error E 0 = |x − x 0| is greater than 1 and E 1 ∼ E , the error of your estimate could actually increase as you apply Newton’s method. In the example f(x) = x2 − 5, if we had chosen x 0 = −2 we would have found the solution − √ 5 and not 5. This convergence to an unexpected root is illustrated in Fig. 1 y = x2-3 x 0 x 1 tangent to

Error Behaviour of Newton’s Method Newton’s method is a procedure for finding approximate solutions to equations of the form f(x) = 0. The procedure is to 1) Make a preliminary guess x 1. 2) Define x 2 = x 1 − f(x1) f′(x1). 3) Iterate. That is, once you have computed x n, define x n+1 = x n − f(x n) f′(x n).
Error Behaviour of Newton’s Method
https://www.math.ubc.ca/~feldman/m120/newtConv.pdf
Newton’s method usually works spectacularly well, provided your initialguess is reasonably close to a solution of f(x) = 0. A good way to select this initial guess is to sketch the graph of y= f(x). In these notes we shall see why “Newton’s method usually works spectacularly well, provided your initial guess is reasonably close to a ...
