When using Newton Method, usually we follow 3 steps:
It should be emphasized the Step 1 is significant and difficult. Since the sequence of approximations may not converge if the initial guess is selected blindly. And, some -time Step 2 is formidable if f(x) is complicated. Moreover, Step 3 always is a time-consuming job. However, HP-48G can help a lot when using Newton Method.
This approach is as follows:
Finally, an example is given to illustrate this approach.
Also, this approach make it easy to grade the problem of Newton Method with different initial guess.
