LL-01 Graphing Calculator

by Yuan Lin & Jennifer Lee

       

 

Introduction:

        The LL01 graphing calculator is a useful tool for calculation and graphing.  There are two different operating modes.  Simple calculations can be done in the calculator mode.  Calculations can be done with these functions: add, sub, divide, log, ln, exp, sin, cos, and tan.  The graphing mode can graph the following functions and their linear combinations:

 

Y=a*x^ (b)

Y=a*sin(b*x)

Y=a*cos(b*x)

Y=a*tan(b*x)

Y=a*ln(b*x)

Y=a*exp(b*x)

Y=a*log(b*x)

 

Motivation to do this project:

        We came up with this idea because most of us engineers use our graphing calculator everyday.   We thought it would be interesting if we can design something that mimics the graphing feature of a TI graphing calculator.
