This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 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 3-D rotations and plot contours.

The manual that ships with the TI-89 is a killer, presenting over 500 pages of clear, concise definitions, function explanations, examples, drawings, and appendices. It's divided into well-organized chapters that cover all the major features of the calculator. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 includes symbolic manipulation, constants and measurement units, statistics and data plots, a numeric solver, a text editor, programming capabilities, tables, a split-screen function, variable management, and the ability to link to other calculators or a computer.

The large, color-coded keys are easy to read and find--a nice touch on such a feature-heavy calculator. An improvement over earlier Texas Instruments graphing calculators is the addition of one-touch 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 TI-89 comes with an attached, hard slide cover that protects it from getting knocked around in a backpack.

The TI-89's flash technology allows you to upgrade to future software versions so you don't have to continually invest in new calculators. The whopping 500 K of memory is more than sufficient for your stored functions, programs, and data. You can also create custom menus or use the default menu. Another cool feature is the Program Editor, which gives you the ability to program. The TI-89 also comes with an input/output port and cable, letting you synch up with other TI-89s or TI-92s. --Jill Lightner

A Calculus trainee Must-have : Texas Instruments TI-89 Advanced Graphing Calculator

I'm a Senior Electrical Engineering student, and I've owned nearly the entire ti-8X line. Based on my expierince the ti-89 is worth the money for two positive groups of people.
1) Lazy people. The 89, when used properly, does almost all of the Algebra that one would encounter in non-calculus based algebra class. It also does most of the calculus that one would see in their first three semesters of college calculus. Thanks to this motor I've forgotten huge amounts of the calculus that I once knew.
2) citizen who need its power. This calculator is almost neccesary for Electrical Engineering majors at my University. It can do impressive amounts of complicated domain algebra, numeric differential equations, symbolic algebra and calculus etc.
----------------------------------------------------------
Who shouldn't buy this calculator?
1) citizen who aren't willing to learn how to use it, and don't need its power. The 89 is fairly intuitive, but still takes some getting used to. If you don't want to spend a nerdy afternoon studying to use your new investment, then you're cooler than me, and should get something cheaper.
2) Lazy People. It's beyond doubt beyond doubt tempting to not learn something in a Math class because your calculator can do the operation. In the long run you will get in issue doing this and the 89 is a very tempting tool in the hands of the indolent.
