Texas Instruments TI-89 Titanium Graphing Calculator - Black Tes
Texas Instruments TI-89 Titanium Graphing Calculator - Black Tes:to ensure you enjoy the best buying experience on the web we've made ordering from us as simple and convenient as possible. TI-89 Titanium calculatorMy primary intent in bidding on this item (TI-89 Titanium hand held calc) was in having an instrument that could create 3D graphs. The unit works well in that regard and you can rotate the finished 3D graph about a vertical or horizontal axis as well....but you cannot graph in cylindrical or spherical coordinates as is required in many engineering and physics problems and to the best of my knowledge there are no programs that you can download into the TI-89 (you can hook it up to your computer and print out graphs with it or simply study them on your desk top screen) that would allow you to do this. Aside from that the unit has performed very well although in honesty I have not had time to fully explore all of the things it can do because I have had too many 3D graphs to have to make for a project. But the TI-89 is crammed with a lot of features for the money.
