TI-89: Unbelievable power?

Date of Review:  Apr 4, 2003
The Bottom Line: Recommended for anyone planning on taking calculus or higher math. It will be worth the investment.
Review: Lets face it: we live in a technological age. I am extremely reliant on my calculator, and most math classes nowadays are intensively calculator based. I agree that it is somewhat pathetic. I cannot image how people took calculus and other high...

Excellent Tool for the Classroom or Office

Date of Review:  Nov 28, 2006
The Bottom Line: Excellent calculator for advanced mathematics, rich in options and functions. Check it out!
Review: I upgraded from my TI-83 to my 89 as a Sophomore in High School. I now keep it with me at work, and have used it in many different academic and professional situations. IT is an incredibly powerful tool, and I'll try to tell you why I'm so happy...

Powerful Calculator

Date of Review:  Apr 23, 2009
The Bottom Line: Again: can be difficult to learn at first, but when you do you'll be glad you chose this calculator.
Review: 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...

WOW!

Date of Review:  Oct 5, 2005
Review: This calculator is amazing. I got it as an engineering student just starting college because I heard its a calculus whiz. It is. It can do derivatives, Integrals, 3D graphs, and solve equations easily. Not to mention there is a Text Editor to type...

Texas Instruments TI-89: Is This God?

Date of Review:  May 1, 2003
The Bottom Line: The Texas Instruments TI-89 is by far the best calculator in the TI-8X series. It's like a God for high school and college!
Review: 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...
