Chapter 10: The SOLVER Feature
Newton&
Newton&bisection method is a technique of finding approximate
bisection
solutions to a math problem via calculus, when conventional
method
algebraic techniques just cannot work. If the Equation method
fails, the calculator will automatically switch to Newton&bisection
method.
