Product Description

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

5.0 out of 5 stars Great Calculator, June 14, 2004

Before I bought a TI-89 Titanium, I had used a TI-83 Plus for four years. After taking calculus and learning about limits, derivatives, integrals, infinite series, Taylor series, differential equations, and multivariable functions, I decided that I would look for a calculator which was capable of symbolic computation. After analyzing my options, I decided on a TI-89 Titanium. The TI-89 Titanium is able to expand polynomials, factor polynomials, and do all of the calculus techniques that I mentioned -- symbolically and numerically. One of the other things I found helpful was the TI-89 Titanium's ability to plot direction fields using different algorithms (including Euler's method). One of the nicer things about this model (compared to the TI-89) is that it has USB connectivity (cord included) for installing applications and transferring data. Another nice thing is that it also supports connectivity to older model TI-89s via the old I/O port which is right next to the USB connector. I also found the "exact mode" very useful (exact mode will give you exact answers rather than decimal approximations). Yet, the most useful feature of this calculator is probably the "pretty print" feature which displays expressions as you would normally write them on paper. This feature allows you to easily see the expression that you typed in. All these features plus copy and paste ability make this calculator nearly perfect. My only complaint is that the cover does not initially slide on and off easily. However, I'm sure that with more use it will wear in. Overall this is a great calculator -- I recommend it

5.0 out of 5 stars For calculus and beyond, perfect! Anything below calculus, this is too much!, June 22, 2006

After using a TI-83 Plus calculator for the last 5 years, I decided to upgrade to the TI-89 Titanium. This calculator is unbelievable in its features and power. First of all, it is more suited for advanced math, such as calculus and beyond. This calculator is NOT meant for high schoolers who are taking algebra, geometry or trig classes. If you don't know what a derivative or an integral is, then save your money and buy a TI-84 instead. (Besides, I believe most high school math teachers ban the TI-89 on tests) This calculator can also run programs in its Flash memory, which can be downloaded from the TI website. A USB cable is included standard. TI has made the newly designed sliding cover much more secure than the old TI design (TI-83 plus, TI-86, TI-89 regular), whose sliding cover was not very secure and became looser over continued use. The cover is very hard to get off the first few times (I was almost afraid of breaking it off), but over time it has gotten easier. Switching over from the TI-83, the only problem I've encountered is the operation of this calculator is very different from the 83. The menus are different, the interface different, different buttons. It takes a while to get used to.

5.0 out of 5 stars Powerful, so powerful, November 6, 2004

This is the most powerful scientific calculator in its class.
If you're majoring in Engineering, or plan to major it, then you must get this one (or regular Ti-89)
If you buy anything else for cheaper price, you'll have to spend $150 more to get this later anyway. (like me)
However if your Math class will end up in Calculus or Algebra(i.e. if you're not going to learn Diff. equation or harder), you don't really need this, you will just waste extra $70 for the features that you will never use (or features that aren't allowed to use in exam)
So think logically. It's really cool looking calculator and it got best software/hardware in the world.
But if one is going to use it for simple graphic or solving polynomial equations, then it's really like simulating windows and playing Doom3 on NEC Earth Simulator..
Used Ti-83 will do as good for those..
