Thread: Newton's method

Solve using Newton's method, giving your answer correct two decimal places.







I can choose an initial value and what-not, no problem. My problem is, when do we stop? When we have reached a stage where has no effect on , where the latter is correct to two decimal places?

You generally stop when the difference between one iteration and the next is smaller than some pre-defined tolerance, such as 0.0001. The tolerance is problem-dependent.
