I teach mathematics at Paradise Valley Community College. We use the TI-83 and TI-84 for just about all our mathematics courses. I have a TI-92 and use a TI-89 calculator for my own use as a tutor. The TI-89 is a true CAS like Maple. The software used in the TI-92 and TI-89 came from the developers of the CAS DERIVE. I would like to have Maple in a calculator like the TI-89. How much would it cost? Who would sell it? The college has Maple, so that I where I use it.
