Texas Instruments 89 Titanium Scientific Graphing Calculator

Includes USB unit-to-unit cable, Connectivity Cable for other TI units and connection software, operating manual Doing complex calculations on a scientific calculator is much easier with the TI 89. Its large screen offers the ability to generate graphs that can illustrate your conclusions. It's especially helpful with statistic functions, such as regression analysis. The TI-89 Titanium includes all the built in functionality and power of the original TI-89. It has an increased amount of Flash ROM 500KB, quite powerful for a traditional handheld design. This is TI's most sophisticated calculator, with such features as 3D graphing, upgradable flash ROM, built-in assembly language programming, and a generous amount of user-available memory. It now includes a mini USB port. This portable symbolic, numeric, and graphing calculator is perfect for advanced mathematics and engineering applications for college and advanced coursework. Its built-in USB port makes Data transfer ultra-convenient.
With three times the memory of the TI-89, you can store more Apps, data, and programs. The TI-89 Titanium's advanced functionality and 3-D graphing make problem-solving for AP, advanced mathematics, and engineering courses infinitely easier. It's the most powerful TI graphing calculator allowed for use on the AP Calculus, AP Statistics, AP Physics, AP Chemistry, PSAT/NMSQT, SAT I , SAT II, and Math IC & IIC exams.
