Amazon.com Product Description
Amazon.com Product Description This advanced graphing calculator is packed with more features than you might know how to use. The TI-89 Titanium lets you perform the expected functions of an advanced model--basic math, algebra, calculus, graphs, matrices, and statistical functions--and do cool stuff like creating animations, graphing 3-D rotations, and plotting contours. Graphing functions include basic function graphing, parametric graphing, polar graphing, sequence graphing, 3-D graphing, and differential-equation graphing. Additionally, the TI-89 Titanium 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 TI-89 Titanium's flash technology allows you to upgrade to future software versions without having to continually invest in new calculators. The 188 KB of RAM, combined with an impressive 2.7 MB of flash memory (three times the memory of the TI-89), are more than sufficient for your stored functions, programs, and data, and add welcome speed to go with the TI's reliability. You can create custom menus or use the default menu. Another cool feature is the Program Editor, which gives you the ability to write custom applications.  The large LCD is adjustable to your environment and can be viewed clearly under a variety of lighting conditions. The calculator also comes with an input/output port and cable, letting you synch up with other TI-89s or TI-92s, as well as a USB port and cable. An attached, hard slide cover protects the calculator from getting knocked around in your backpack. The manual that ships with the TI-89 Titanium 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. What's in the Box
The TI-89 Titanium, a hard sliding case, a silver oxide battery, a user's guide, an applications CD-ROM, a USB cable, a TI-link cable, and warranty information
Product Description
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. Built-in Flash memory for archiving data(2.7MB) Finance tools, Organizer, Polynomial Root Finder, Simultaneous Equation Solver, and many more apps Fully upgradeable (electronically) through its Flash ROM chip (optional TI Graph-Link required) Computer Algebra System, differential equations, 2D-graphing and data analysis, 3D-graphing with rotations, linear algebra, interactive numeric solver, constants, unit conversions, statistical regressions Optional Assembler language Mathematical expressions appear on the display the same way as they are usually written in class or in published texts and academic journals StudyCards and Symbolic Math Guide for helping students learn more effectively Preloaded with Official AP Calculus exam review questions Built-in USB port for easy data transfer between handhelds - The TI Connect allows rapid data transfer to computers

 good stuff November 6, 2009

pretty nice calculator...cute..just an updated version of the one i had..a lot cheaper than the one at our school bookstore
A (very useful) niche item November 4, 2009
D. McCurdy (St. Louis)
For pre-calculus and first-year calculus classes, this calculator is *probably* overkill and could even end up detracting from your understanding of the material, if you are using it instead of learning to do the integration and derivatives.
For higher level classes, however (Multivariable calculus, Differential equations, quantum physics) I would definitely recommend the Ti-89. For math classes, where the main part of the problem consists in *constructing* an integral rather than solving it, it's great to be able to check things quickly so that you don't go through unnecessary work solving an integral that wasn't right in the first place. For some of my science classes (quantum physics) this calculator has been indispensable.
There are other comparable calculators out there, but if you aren't familiar with those options, the Ti-89 is the safest bet, and you can be fairly sure it's what most other students will be using. The learning curve isn't going to be perfectly smooth for most people, but it's much easier to find someone who can explain a particular feature if you're not the only one in the class using that type of calculator. In summary, thanks to the Ti-89's fairly full feature set and prominence in academia, I definitely recommend this calculator.

The TI-89 is great, pretty easy to use, but you need to play around with it to get the hang of using it. Compared to the older versions, simple calculations requires you to punch in extra buttons to calculate such as the cosine, sin and tan buttons. Overall its a great calculator.

Dude this is the best Calculator available! It is the top of the line. I also have the HP50g and I would highly reccommend the ti-89. Also on a side note if you get the ti-89 i also loaded an app onto it called "Calculus Made Easy" that does step by step soultions to most calc 1,2 and 3 problems. It was great along with my ti89 for working homework problems and filling in the blacks that I missed during lectures and reading.
TI 89 review for EE major October 30, 2009
Cassidy Ferrel (san antonio texas)
This calculator should be only used in Calculus 3 or above. If you do not plan to go beyond calculus 2 i would not get it unless you like to check your answers. This calculator is very easy to use once you read the manual but lacks the power my HP50G has. However, for use in school its fine.
