**1. How many iterations should be done when using the Newton-Rhapson method?**

The number of iterations depends on the number of decimal places required.

**2. How do I know when to stop when using the Newton-Rhapson method?**

There are two ways:

If working to 2 decimal places, continue until the difference between successive iterations is < 0.01

ORContinue until both x

_{1}and x_{2}have the same value, when rounding to the desired number of decimal places.
