A great tool for calculus and physics
This is an excellent tool for anyone taking upper level math or physics courses. It brought me safely through Calc I, II, and III, and has served me well through my undergraduate physics study. This calculator has been able to take virtually all integrals I have given it, which never fails to impress me.
My one complaint is that the graphing technology seems a bit outdated; it's certainly better than the TI-83 Plus, but not by that much. Graphics are basic black-and-white, and are rather coarse. A higher resolution screen and heftier processor would be a welcome addition, which is why I gave it 4 stars. However, I have yet to see a hand held calculator that can match this one's abilities and as such highly recommend it to anyone ... Read More
Essential for Calculus
This is absolutely essential for anyone taking a Calculus class. This is especially true for later on, such as in the later half of Calc 2 and all of Calc 3. After learning how to manually evaluate integrals and differentiate, as you move on to higher level concepts the 89 titanium can be used to do these manual tasks for you, allowing you to focus on the new material and allow you to practice more without wasting time on repetitive evaluations. I love this thing, and would not take Calc and Physics without it.
Great deal!!!
They were fast and was a lot cheaper than a lot of the other vendors. The product was used but in great shape just like they said it was. I would certainly buy from them again.
Excellent Calculator
I bought this calculator for my grads math and engineering courses and it works perfect. There are some many features which make this probably the best calculator on the market. Yes, now TI launched the Nspire and Nspire CAS, but to be honest, those calculator are far away yet from the Ti-89 Titanium in one of the most important thing: support (programs, applications, etc). I'd wait at least two years to see if TI give more support for the Nspire series, meanwhile I think the Titanium is a powerful machine with advanced functions (numerical and symbolic) and a very decent memory for most of engineering applications.
Great Calculator
I'm an engineering student, and this calculator is a MAJOR UPGRADE over a TI-83/TI-84. It can do so much more once you learn how to use it, and it has helped me on my calculus homework more times than I can count.
It is a must have for any engineering/science student.
