When using Newton's method to approximate roots, my teacher shared with us a method to expedite the process using a calculator. These instructions are for a TI-84 but they should be generally applicable.

Initially, enter your guess for x, and press enter.

Then, enter the following expression: ans - f(ans)/f'(ans), replacing the functions with their respective expressions: say, if f(x) was x^2-1, the expression entered would be ans - (ans^2-1)/(2*ans).

By pressing enter, you will get the result for the next iteration of the root. To iterate again, press 2nd-enter to call up the expression again and then press enter.
