CAS graphing calculator with QWERTY keyboard

The Voyage 200 let you easily customize your handheld by adding new functions through software applications. The Computer Algebra System (CAS) enables you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate) and easily evaluate mathematical expressions symbolically or numerically.

Differential-equation features let you compute exact symbolic solutions to many 1st- and 2nd-order ordinary differential equations. Solve single differential equations or systems of them using Euler or Runga Kutta methods, and graph slope fields and direction fields. Pretty Print allows mathematical expressions to appear on the display the same way they look on a blackboard or in a textbook.

With the StudyCards App your TI-89 or Voyage 200 can be used for almost all classes: history, foreign languages, English, math, and others. The easy-to-use PC software allows you to create StudyCards for specific subjects and topics. Review topics between classes, on the bus, and at home, with the press of a button.
