Texas Instruments TI-89 Titanium Scientific Calculator

Pros: great math capabilities, very powerful
Cons: can be difficult for beginners

I fell in love with the TI89 about a year ago, this was after over a year messing around with TI86s and TI85s. But the TI89 was so much more...

The TI89 has pretty much all the 86 has, and more. Lots more functions, including powerful...

Pros: Advanced Math features
Cons: Hard to use, Missing some important features

I had a TI 89 graphing calculator, and I did not like it. The TI 89 is really unnessary, unless you are in an advanced math class(i.e,Calculus, Statistics). For all of those in Algebra, Geometry, or Trig this calculator is probably not what you want. I...

Pros: easy to use, easy to understand
Cons: none!

I bought this calculator upon arriving in college at the Air Force Academy and discovering that my other calculators were obselete for the mathematics required for many courses.

I am a calculator/mathematically-challenged cadet who bought...

Pros: Huge memory, lots of options
Cons: a little confusing until you actually find someone who knows it

If you're out on the market for a calculator, buy a Ti-89. There are so many reasons to buy them, but I will list just a few. First of all is the fact that 89's have more memory than a 20 year old computer. This is so obviously cool because of all the...

Pros: A lot of features
Cons: Difficult to get to what needs to be done

I used to own a TI-86 calculator, but forgot it at a hotel while on a business trip. I decided that if I'm going to buy another calculator, might as well upgrade. So I bought the TI-89. This calculator does all that the other calculator did, and more,...

Pros: Does SO many different things!
Cons: Not easy to operate

This calculator is a students best friend. It does differentials and integrals for you! Almost every thing you can possible do in calculus can be done on this calculator. It is hard to find some of the operations and functions on there because there...

Pros: great display, incredible capabilities
Cons: difficult to figure out, poor instruction manual, expensive

The TI-89 is certainly an amazing calculator. It has incredible capabilities. Very useful for calculus and physics, among other things. However, its complexity does make it difficult to figure out. The user manual is quite large and it would be very...

Pros: does a multitude of things. expandable and upgradeable memory
Cons: sometimes too complex

I personally own this product and use it almost everyday in my calculus course. Although the product is some what difficult to master and is quite complex it is worth it considering it capabilities. The TI-89 is capable of easily and accurately solving ...

Pros: able to do many more things than the TI 86
Cons: expensive, somewhat overwhelming features

I purchased this product last week for my college calculus class, which basically requires the use of this calculator. I had been using a TI-86 which i thought was wonderful for about three years. The TI 89 is an excellent tool. It provides excellent...

Pros: Great
Cons: Not many

This calculator is a fairly useful product. I used it in my math courses in the past few years. It i ...

Pros: tons of functions and incredible memory to store many programs
Cons: very complex and sometimes difficult to use. it is a little costly too

I began with the TI-83+ and became very good at programming and using its functions. When I received a TI-89, I thought I could use it with ease, but was I in for a suprise. The calculator is extremely complex and I wouldn't recommend it as your first...

Pros: useful, compact, easy to operate
Cons: expensive, will be outdated in a few years

I bought this calculator for my combined calculus 1 & 2 class. I can honestly say that I would not have passed without it. In an era when science and math rely heavily on calculators and computers, students must be prepared to deal with the...

Pros: will solve anything, 3D graphing
Cons: the instruction manual is the size of a novel

The TI-89 leads the way in calculator technology. When I lost my TI-86 and had to buy a new one I went with this. And have not looked back. This thing does everything. It solves just about any type of problem with algebra functions, calculus function, 2D...

Pros: Very versatile!
Cons: Complicated

TI did it again with its ti-89. It comes at a hefty list price of about 150 dollars, but I bought it on ebay for only 80$. The calculator is very complicated, but not too hard if you take the time to look at the manual and to learn how to do a new...

Pros: Clear Display, lots of memory, elaborate features
Cons: price, but not too bad for its worth

I bought a Ti 89 for my high school math course. Before I bought it, i thought it was going to be so very hard to use. I am not very good at figuring out things like that. It only took a couple of minutes of playing with it, before I knew how to do most...
