Newtons method?
(OP)
When using iteration, how do you know if:
- if you are not getting convergence?
- that the result is good and you have not simply reached the iteration limit?





RE: Newtons method?
Excel uses Newton's method. How you terminate the process or check for errors is not described in Newton's Method.
The easiest way to check is to compare the solution to the graph of the function.
