Excursions with the TI-81 Graphics Calculator in College Algebra.
Spears, Sandy; Ehringer, Margaret
College algebra is currently being taught using graphing calculators such as the TI-81. This document presents exploratory and problem solving activities that have resulted from classroom experiences with the TI-81. The activities have been designed to enhance the learning of some standard college algebra topics through the easy access to visualization provided by the TI-81. The activities incorporate the following topics: (1) interpretations of the graphs of functions modeling real world problems; (2) shifts and translations of basic functions; (3) intersections of curves; (4) solutions of equations and inequalities; (5) graphs of rational functions; (6) graphs and applications of exponential functions; (7) graphs and applications of logarithmic functions; and (8) zeros of polynomials. A list of selected answers to problems posed in the activities is provided. (MDH)
