Could someone please so me how Newton's Method is used in Numerical Analysis? My teacher is doing a horrible job of teaching it and he skips a lot of steps.

Newtons Method:

X(n+1) = x(n) - f(x(n))/f'(x(n)) (n) is a subcript to x.

It is a method to find the solutions to a function using the derivative and the original function only

For example consider

We have to make an initial guess..lets say 2

So we set up our first iteration

C is just because I dont have my calculator

So then

and then obviously

and as the iterations will yield that zero of th function - June 12th 2008, 01:10 PMarbolis

Thanks guys. Newton's Method seems to be very simple to understand. It just was my teacher, who cann't really teach but he knows his stuff. Mainly I see that you can manipulate problems in many ways to get your desired outcome.(Rock)
