Product Description
Amazon.com Product Description
Amazon.com Product Description With more power than most of us had in our PCs less than 20 years ago, the TI-92 Plus graphing calculator is the machine of choice for students and engineers both at the desk and on the go. It comes with over 500 KB of memory and software for working through algebra and other mathematic problems quickly and easily. 
With the TI Graph Link accessory (not included), you can connect to computers and even download software upgrades. Solve linear and nonlinear equations, use the Pretty Print feature to see equations in textbook format, and work with 3-D surface graphs in real time. The QWERTY keyboard is rugged and easy to use, the 128 x 240 screen is easy on the eyes, and the calculator comes with a durable shell to protect its face when you're traveling or in the field. Additional accessories can turn the TI-92 into a mobile data-collection station, but it's just as useful at home.
Students beware: Some professors and teachers discourage, or even ban the use of calculators like the TI-92 in their classes, so make sure it's OK before you buy. Once you're set, the manual is clear and straightforward--you'll be programming in no time. Ultrageeks will love the assembly-language option, but the rest of us can get by just fine with the regular interface. The old timers might still cling to their slide rules, but anyone who needs a calculator for school or work can see why the Texas Instruments TI-92 is so popular: Its versatility, power, and portability give you the number-crunching power of a computer no matter where you are. --Rob Lightner

As good as a calculator gets!!,

This review is from: Texas Instruments TI-92 Plus Graphing Calculator (Office Product)
Being a math and computer science major, I thought a more powerful calculator would probably come in handy. Simply put, this calculator can perform about any mathmatical function that I've wanted to use it for. Furthermore, when I find a function missing that I need, this calculator has sufficient memory and an easy-to-learn programming system to implement your own functions or programs. The TI 92 can perform mundane calculations that would be helpful in high school classes, but it is really intended to be used for the more complex ideas that upper level college courses make a student work with. It should be noted as well that some professors will not allow the use of this calculator on exams and the SAT and some other standardized tests definitely will not allow it. In my personal experience, I took a Numerical Methods math course which actually referred to my calculator several times and presented me with code on how to implement the complex equations in the TI 92. Furthermore, my favorite feature of this calculator is the "Pretty Print" function. When this feature is on, the calculator will print most math structures just as they would look in a math book. (derivatives and integrals are a simple example of this feature.) One negative aspect should be pointed out as well, because of the sheer quantity of features on this calculator, it can be difficult to learn how to use it quickly. The instruction manual is huge, but it does feature many helpful examples if one takes the time to read through it. Finally, the addition of the "QWERTY" keyboard is very useful and most people will probably wonder how they ever used a graphing calculator without such a keyboard. In conclusion, this calculator is powerful, but it can be overwhelming at first. It handles simple problems and some of the hardest mathmatical functions possible with ease. Therefore, in my opinion, this calculator is a perfect fit for a math major in college or a person in a mathmatically related profession. Others, would probably be better off to save the extra money and get the TI 89.

Probably the best out there,
By A Customer
This review is from: Texas Instruments TI-92 Plus Graphing Calculator (Office Product)
I've owned my TI-92 Plus for about a year now and I have been very pleased. I've also owned the 81, 83, and 85 but this is no comparison. If you're still in High School DO NOT buy this, buy the TI-89. This calculator is not allowed on the standardized tests and most teachers won't allow it. The 89 isn't quite as nice IMHO, but is does almost all the same stuff. 92 Plus has better graphics and also can do Geometry.

Excellent Calculator,
By Ross Schaefer (rschaefe@iastate.edu) (Ames, Iowa) - See all my reviews
This review is from: Texas Instruments TI-92 Plus Graphing Calculator (Office Product)
I've owned and used a TI-92 for two and a half years now as a construction engineering student at Iowa State. This calculator is unbelievably powerful and has been a great help in all types of classes. It can solve equations symbolically, solve multiple equations in multiple unknowns, do some awesome 3-D graphing of upper level calculus functions, analyze spreadsheets on information for statistical variables, pretty much anything you want. The only small gripe I have is that it does not do automatic unit conversions like the TI-86 did. So you need to look up conversions factors, oh well. This calculator is what 95% of engineering students at Iowa State use. It is indispensible.
