Works great for my high school son
Works great for my son who is in high school. Apparently whatever model the teacher uses has a few keys that are in different spots so not every function works using the exact same keys, but that has not been a problem for my son. However, if your child's teacher uses a specific model I would suggest getting that model instead so that learning would be easier for someone not as technologically inclined as my son.Works great for my son who is in high school.

Astounding functionality and computing power! But not beginner-friendly.
I bought this calculator for my advanced level Calculus and Physics courses. Its functionality and computing power are astounding. I've used a TI-84 and TI-83 in the past, and the possible functions of those calculators pale in comparison to the TI-89 Titanium. It does almost everything I could want it to; it solves equations, differentiates, integrates (both definite and indefinite integrals), and graphs in three dimensions--slowly but that's to be expected, it's only a calculator. This last function is extremely valuable in multi-variable calculus. The screen is black/white but can still produce images with nice contrast. The main difference between this one and the TI-nspire is that the nspire has a colored display and a nice input keyboard, however, it lacks the ...

This last function is extremely valuable in multi-variable calculus. The screen is black/white but can still produce images with nice contrast. The main difference between this one and the TI-nspire is that the nspire has a colored display and a nice input keyboard, however, it lacks the computing power and 3-d graphing features of the TI-89 Titanium. I am certainly not a beginner with TI calculators, but sometimes this calculator can still confuses me. My biggest complaint would be that it is NOT BEGINNER FRIENDLY. A second complaint would be about the input, which is sometimes cumbersome, but still effective (the input is no different than that of a TI-84 or 83). Another thing to note would be that most of the buttons on the TI-89 Titanium are placed differently than on the TI-84 or 83. I would recommend this calculator to anyone that is adept with graphing calculators or needs the extra functionality of the 89. Also, the price is not exorbitant, or even much more than the other TI graphing calculators.

TI-89 Titanium calculator
My primary intent in bidding on this item (TI-89 Titanium hand held calc) was in having an instrument that could create 3D graphs. The unit works well in that regard and you can rotate the finished 3D graph about a vertical or horizontal axis as well....but you cannot graph in cylindrical or spherical coordinates as is required in many engineering and physics problems and to the best of my knowledge there are no programs that you can download into the TI-89 (you can hook it up to your computer and print out graphs with it or simply study them on your desk top screen) that would allow you to do this. Aside from that the unit has performed very well although in honesty I have not had time to fully explore all of the things it can do because I have had too many 3D graphs to have to make for a ...

But the TI-89 is crammed with a lot of features for the money.

Your new best friend in Calc class
I started my calc class with a TI-83 Plus that I used for all my other math classes. It was fine in the beginning but I felt I was wasting a lot of time doing "busy" work. This TI-89 does all the busy work for me! I now have more time to work on the actual problem that other stuff such as finding the derivatives and solving equations. This is a great handy tool to check over your work to make sure you have not made any careless errors. I have never used the Titanium version but see no downfall to using the original version. Here are some pros and cons that I feel go with this calculator. Pros: Derivatives, Solving Equations, Low Battery Meter. Cons: Price (if purchased new), Graphs can be a little hard to view. My overall opinion: If you are planning on taking a ... I started my calc class with a TI-83 Plus that I used for all my other math classes.

My overall opinion: If you are planning on taking a Calculus course try to pick up one of these used and become familiar with it because it will seem very foreign at first. And don't replace this with knowledge, you still need to know the basics in your head in order to succeed in the class!

Excellent Value
My daughter is taking Calculus next year in high school and (of course) the teacher required the students to have the TI-89 calculator. I was not exactly pleased that I would have to purchase yet another calculator since we already purchased the TI-83 and TI-84 for previous math courses. The calculator is a very cool piece of technology. It works beautifully and will (I hope) be useful for my daughter through her college years. It has many other features that you download easily from the Internet to do other types of functions, such as finances, statistics, and an organizer (to name a few). I also found out that it has AP Calculus test questions pre-loaded on it, which will be useful at the end of this school year. Our vendor was efficient and quick to send us the product. Even ...

Even though I really didn't want to purchase yet another calculator, I am extremely pleased with my purchase. This calculator functions more like a mini-computer, and with the Internet interface, my daughter will be able to use this for any engineering, math or science class in college.
