Texas Instruments TI-89 Titanium Graphing Calculator
I have purchased many Texas Instruments Graphing Calculators over the course of my school career and I have to say that the TI-89 Titanium is by far the best yet. TI appears to have combined the best of all the other calculators into one unit, expanded its memory capacity, given it a faster... Read full review »

TI-89 Titanium
*Note: This review pertains to the TI-89 Titanium, which is newer than the regular TI89.*
What a calculator! In middle school math, I had a scientific calculator. Back then, scientific calculators seemed like the most advanced calculators out there. And then along came high school. It is...

TI-89 Titanium- arrrgh!!!!
Having been an electronics engineer for 20 years, I use calculators quite a bit. I decided it was time to replace my dozen year-old HP 28S with the biggest, baddest TI available. Now, I'm thinking that was a mistake. The features on this calculator are very poorly integrated. TI seems to have taken... Read full review »
Powerful and Durable
I've had my TI-89 for almost 4 years now and it still runs as well as the day I bought it. It's been dropped, banged around, had water spilled on it, and I'm still running it. It's most possibly the best graphing calculator Texas Instruments (TI) makes. There are some other models that TI makes... Read full review »
Why did I wait soooo long?!
I'm a third year electrical engineering student and have used a TI-86 until three weeks ago. Now the TI-86 is a fine unit...But the TI-89 is absolutely an AWESOME piece of equipment! I had seen the TI-89 here and there but until I had my own TI-89, I had no idea of the capability of this... Read full review »
Far better than repeating a semester.
Recently I started my final semester of calculus. This device is my sole ally when facing things like R3-functions and partial derivatives. It takes much of the heat off of me and I rely on it heavily. Truthfully, it is hard to learn to use. I've had mine through Trig, College Alg, Calc-1, Calc-2,... Read full review »
simply the best
I originally bought the TI-89 because I was going into engineering and it looked like the best deal at the store. Three years and two majors down the road, I am so thankful that I made this choice. The calculator is easily worth a letter grade in Calc I, II, and III. Not to mention every other math... Read full review »
TI-89 Graphing Calculator: "Summed" Up
This calculator is a fairly useful product. I used it in my math courses in the past few years. It is not very hard to find the correct basic functions and master the keys, but you can also get into some fairly advanced things on this calculator. There are different "modes" available which allow... Read full review »
Texas Instruments TI-89: Is This God?
The Texas Instruments TI-89 is the most expensive and advanced calculator in the TI-8X series. It's much more money than either the TI-83+ or TI-86. However, the difference in price is worth it when you see the capabilities that the Texas Instruments TI-89 has. I bought one to use in college after... Read full review »
