3-2 Solve Calculations

To solve calculations, first display the function analysis menu, and then input the
values shown in the formula below to determine root
P.64
With Solve calculations, the root of a function is determined using Newton's method.

This method is based on the assumption that
expression within a very narrow range.
First, a starting value (predicted value)
