Texas Instruments TI-89 Texas Instruments TI-89 Titanium Graphing Calculator

Ideal for University or College Math Physics Engineering Product Information Texas Instruments is the leader in handheld educational technology.  TI-89 Titanium is the next generation of TI s most powerful educational handheld for use in advanced mathematics and science courses. The TI-89 Titanium includes a new built-in Universal Serial Bus (USB) port to allow for direct data transfer between computer and handheld as well as between TI handheld graphing devices. In addition to this increased functionality the TI-89 Titanium is also redesigned with a sleek new look while maintaining the same keystrokes as its predecessor the TI-89. This powerful graphing handheld offers students in high school advanced placement (AP+) and college-level mathematics and science courses the highest level of functionality and applications to meet their specific classroom needs. With more than 2.5M of available Flash memory and 188K of available RAM this product is the most powerful TI tool allowed on many AP+ exams including AP Calculus Physics Chemistry and Statistics. The device comes preloaded with 19 Handheld Software Applications (Apps) including CellSheet a spreadsheet application; Symbolic Math Guide a tutorial for transformations for problems in algebra pre-cal and calculus; and EE*Pro an all-inclusive App for electrical engineering. "With direct USB connectivity the TI-89 Titanium represents the most powerful handheld tool to aid students with some of the more complex processes involved with heavy academic lifting " said Susan Herman Product Line Strategy Manager for Texas Instruments Educational & Productivity Solutions business. "Because TI develops its products with direct input from educators we re confident that both students and teachers will find the TI-89 Titanium is unmatched in functionality and usability." By connecting a USB cable to the TI-89 Titanium s built-in USB port users can customize their units by downloading various TI Apps from a computer. The unit also comes equipped with a powerful organizer so teens can track and store tasks class schedules appointments phone numbers and other important information. This portable symbolic graphic unit comes complete with a symbolic Computer Algebra System (CAS) Advanced Mathematics Software and Flash technology that enable students to perform 3-D rotations symbolic manipulation and upgrade the unit s software electronically.
