Hey guys, i have a relatively simple problem. I need to use netwon's method to find the root of a polynomial, lets say x^3-2x-1
i start off with p <- function(x) x^3-2*x-1 My method, which im sure is very amateur, is to type another function, which is the derivative of p, and after picking an initial value to start off with, i follow the steps of newton's method manually, but i dont think that is what the question is asking. I've done some research on wikipedia, but i cant seem to find any code that will help me. Can someone help? Thanks a lot _________________________________________________________________ [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
