Essential for AP Calculus, college math, and beyond, the TI89 is the most logical handheld technology for advanced mathematics studies. Enhanced with Flash technology, this handheld gives you the flexibility to add calculator software applications and additional functionality, providing longterm value.
Builtin advanced mathematics software includes a Computer Algebra System (CAS) enabling you to manipulate mathematical expressions and functions (factor, solve, differentiate, integrate, and more). It also includes differential equations, 2D graphing and data analysis, 3D graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions, and optional assembly language programming.

Description
This advanced graphing calculator is packed with more features than you might know how to use. The TI89 lets you perform the expected functions of an advanced calculator–basic math, algebra, calculus, graphs, matrices, and statistical functions. However, you can also do cool stuff like create animations as well as graph 3D rotations and plot contours.
The manual that ships with the TI89 is a killer, presenting over 500 pages of clear, concise definitions, function explanations, examples, drawings, and appendices. It’s divided into wellorganized chapters that cover all the major features of the calculator. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3D graphing, and differentialequation graphing. Additionally, the TI89 includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a splitscreen function, variable management, and the ability to link to other calculators or a computer.
The large, colorcoded keys are easy to read and find–a nice touch on such a featureheavy calculator. An improvement over earlier Texas Instruments graphing calculators is the addition of onetouch X, Y, and Z variable keys. The large LCD screen is also adjustable to your environment; we were able to view it clearly in a variety of lighting. The TI89 comes with an attached, hard slide cover that protects it from getting knocked around in a backpack.
