Texas Instruments TI-89 Titanium Scientific Calculator

The Bottom Line: The TI-89 is a very powerful device. It made my high school calc class a ton easier and I believe it will do the same for any customer.

Review: 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,...

The Bottom Line: A great calculator for college-level math and science nerds, but most high school students are better off with a TI-83 Plus.

Review: For three years of high school math (precalculus, calculus, and linear algebra), I happily used my school-issued TI-83 plus. It was perfect for precalculus, and it was useful for calculus, too, but by senior year I was taking multivariable calculus,...

The Bottom Line: The calculator is a must for all math and engineering fields of study!

Review: 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...

Review: 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...

The Bottom Line: I would definitely recommend this calculator to anyone who wants an extremely powerful calculator that can do a lot more than just math...

Review: This is what some people sometimes joke about when I pull out my TI-89 graphing calculator, because that's really how powerful it is. I have practically the newest version, with Hardware version 2, and AMS (Advanced Mathematics Software) 2.05, and...

The Bottom Line: If you have the money, buy it!

Review: I would not have survived Algebra II if I had not purchased the TI-89. It saved me countless hours of laborious work, which would have been unnecessary because I already understood the concepts, just that my scientific calculator would force me to...

The Bottom Line: Good calculator all in all.

Review: 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...

Review: s off to a rousing start. Both are great examples of what Buckcherry can do when they put the pedal to the metal. If not for the fact that they are once again swimming in the Crowes pool, these songs would be some of their best work. Originality was...

Review: This is about as awesome as your graphing calculators get. It's very advanced, and even has a periodic table. This is a great calculator, it has everything you need, and then some. It's loaded with extras. The only bad thing about it is, many...

Review: 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...
