Titre de la communication :	Exploring Mathematics with the TI-89 Titanium and the Voyage 200
Résumé de la communication :
Handheld CAS's now have enough memory combining RAM, archival memory, and flash ram that they now can be loaded with several new tools such as a cell sheet, dynamic geometry, numeric solvers, Symbollic Math Guide, and Calculus Tools. This is in addition to the standard symbollic operations, graphing capabilities, text, list, and data/matrix editors, etc. that already exist on the TI-92 plus and TI-89. In this "hands-on" workshop we will show ways to use this integrated package to assist in the learning of mathematics. We will use the handheld CAS's to demonstrate applications in Elementary and advanced algebra, general interest mathematics, calculus, and statistcs. We will investigate solving polynomial exponential equations, using the Symbollic Math Guide, public key crytography, choosing regression equations, and a symbollic spread sheet.
