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 »
An Engineering Dream
To start, I will talk about who I am and why I use the TI89 calculator. Currently, I am a mechanical and aerospace engineering student at West Point. Last year my school was rank second and fifth in civil and mechanical engineering, respectfully. To be an engineering student at West Point, a cadet... Read full review »
This thing is GOD!
I had a TI-83 that I bought for graphing back in the days of Algebra 2. For calculus however, I was told to buy a TI-89. Man, this thing is amazing. It takes a few days just to get through its nasty Windoze style menus, but once you do the abilities of this thing are endless.
The TI-89...

After trying so many calculators...
Hi, my name is Kelly. You may remember me from such reviews as "Bad Deal For Students," reviewing the TI-92. I'm here today to inform you of a discovery that has made my life just about perfect. After buying the TI-89, my grades improved, I met my lifelong love, and my broken arm healed. Actually,... Read full review »
Great Calculator but use with care...
The TI-89 is a super calculator -- beyond the fact that it will do symbolic manipulation, I love most its 'pretty print' feature that allows a student to view a problem much like it would be written in math class. Limits, radicals, derivatives, and more are all shown on this calculator like they... Read full review »
Great Calculator, But Not For Kids
Originally, I bought the TI-89 for my math classes in High School. This was both a good and bad decision. The TI-89 is indeed a truly amazing calculator. It can figure out most lower level math problems all by
itself. All you do is enter in the entire problem, and it will solve it for...

This is the way to an A in highschool math.
This calculator is what a struggling math student needs in highschool. I am have taken Algebra 1 and 2, Precalculus, and AP Calculus AB and loved what this calculator does. It has all of the basic requirements you can find in a TI-83 and TI-86 which I was forced to use until last year when the 89... Read full review »
Powerful, Useful, Pretty buttons.
I have had my TI 89 now for almost two years, and I love it to death. I think it would be best for my to start out naming my favorite features. It has THE number one feature I believe that a calculator could have which is a 30 operation memory. This means that when I hit 2 + 2 and it gives me 4 ten... Read full review »
Powerful Calculator
Like any new calculator, the TI-89 takes some getting-used to. It takes a while, actually, to understand everything that it is capable of. I am a mechanical engineer, and i am still somewhat young, so it did not take me all that long to figure out a few tricks on it by just playing around (although... Read full review »
Ti-89
I picked up the TI-89 calculator for high school, and I'm very amazed at all the things it can do. My teachers recommended the Ti-83/84, but it was on sale at the time, and they were out of the 83s.
The TI-89 calculator comes with everything, and I mean everything, you will need for high...
