This advanced graphing calculator is packed with more features than you might know how to use. The Tl-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 Tl-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 Tl-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 Tl-89), are more than sufficient for your stored functions, programs, and data, and add welcome speed to go with the Tl'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 Tl-89s or Tl-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 Tl-89 Titanium is a killer, presenting over 500 pages of clear, concise definitions, function explanations, examples, drawings, and appendices. lt's divided into well-organized chapters that cover all the major features of the calculator.

What's in the Box
The Tl-89 Titanium, a hard sliding case, a silver oxide battery, a user's guide, an applications CD-R0M, a USB cable, a Tl-link cable, and warranty information

Buyer's feedback: - * A great tool for calculus and physics ...
This is an excellent tool for anyone taking upper level math or physics courses. It brought me safely through Calc I, II, and III, and has served me well through my undergraduate physics study. This calculator has been able to take virtually all integrals I have given it, which never fails to impress me.

My one complaint is that the graphing technology seems a bit outdated; it's certainly better than the TI-83 Plus, but not by that much. Graphics are basic black-and-white, and are rather coarse. A higher resolution screen and heftier processor would be a welcome addition, which is why I gave it 4 stars. However, I have yet to see a hand held calculator that can match this one's abilities and as such highly recommend it to anyone working with math beyond trig.

Buyer's feedback: - Essential for Calculus
This is absolutely essential for anyone taking a Calculus class. This is especially true for later on, such as in the later half of Calc 2 and all of Calc 3. After learning how to manually evaluate integrals and differentiate, as you move on to higher level concepts the 89 titanium can be used to do these manual tasks for you, allowing you to focus on the new material and allow you to practice more without wasting time on repetitive evaluations. I love this thing, and would not take Calc and Physics without it.

Buyer's feedback: - * Great deal!!! ...
They were fast and was a lot cheaper than a lot of the other vendors. The product was used but in great shape just like they said it was. I would certainly buy from them again.

Buyer's feedback: - Excellent Calculator
I bought this calculator for my grads math and engineering courses and it works perfect. There are some many features which make this probably the best calculator on the market. Yes, now TI launched the Nspire and Nspire CAS, but to be honest, those calculator are far away yet from the Ti-89 Titanium in one of the most important thing: support (programs, applications, etc). I'd wait at least two years to see if TI give more support for the Nspire series, meanwhile I think the Titanium is a powerful machine with advanced functions (numerical and symbolic) and a very decent memory for most of engineering applications.

Buyer's feedback: - * Great Calculator ...
I'm an engineering student, and this calculator is a MAJOR UPGRADE over a TI-83/TI-84. It can do so much more once you learn how to use it, and it has helped me on my calculus homework more times than I can count.

It is a must have for any engineering/science student.
