ABSTRACT

Students often use calculators without understanding how they derive their values. To illustrate the mathematics behind such approximations, the Taylor series, Padé approximations, and the CORDIC method are used to approximate values for various functions and are implemented in a Flash program which will simulate a graphing calculator.
