The TI-89 Titanium graphing calculator
This guidebook provides information about a powerful, advanced
graphing calculator available from Texas Instruments: the TI-89 Titanium.
Your TI-89 Titanium comes equipped with a variety of preinstalled
software applications (Apps) that have features relevant to many
different subjects and curriculums.
Using Flash read-only memory (ROM) for the TI-89 Titanium (4 megabytes
[MB] available), you can install additional Apps and increase the
capabilities of your calculator. Installing Apps and operating system (OS)
upgrades is like installing software on a computer. All you need is
TI Connect™ software and a TI Connectivity Cable.
The TI-89 Titanium graphical user interface (GUI) and configurable Apps
desktop make it easy to organize Apps into categories that you create.
Extend the reach of your TI-89 Titanium with accessories, such as the
Calculator-Based Laboratory™ (CBL 2™) systems, Calculator-Based
Ranger™ (CBR™) system, TI-Presenter™ video adapter, and
TI ViewScreen overhead panel.
The CBL 2 and CBR systems offer static and real-world data collection.
Use the TI-Presenter video adapter to connect the TI-89 Titanium to video
display/recording devices, such as TVs, VCRs, video cameras, and
computer projectors. The TI ViewScreen overhead panel lets you project
an enlarged image of the TI-89 Titanium display so an entire class can
view it.
