Don't use them much any more, of course. They were cool for graphing, but were banned in every single unversity class I had and only the 49G came in handy because it would happily perform derivation and integration with variables and was useful for checking answers on homework.
Which is fine, anyway. A basic scientific calculator is more useful once you learn the basic concepts of equations anyway, since it doesn't act like a crutch in the way that a graphing calculator does.
There isn't really any point in getting a TI-89 if you plan do use it for standardized tests in the near future; it will definitely help you solve problems, but it will take time to learn how to use, and most of the problems it can solve aren't the hard ones. Also, as people have said, you can't use it on the ACT (although you could if you tried...)
Yeah, the TI-84 Plus SE is what I have, and it is what I would suggest buying because it is widely used (especially in high school calculus / statistic classes), and it can be found for pretty cheap on ebay.
depends on what you need it for. i use a TI-83 plus but TI-84's are almost the same thing just faster and more memory. most people i know in calculus use an 83 or 84. never used an 89, those are for pretty advanced math. if you're in highschool i'd say an 83 or 84. they have the same functions and abilities but if you have the money go for the 84.
I'm surprised teachers are letting algebra classes use graphing calculators. Most would only let me use a scientific. I even had one that would only let us use calculators on logs, nothing else.
TI-89 is a godsend in engineering school:)dgbiker1
I agree.
Even outside of engineering courses it can do just about anything but it ends up being restricted sometimes due to the amount of things it can do. But if all else fails go with an 83 or 84.

The only time it's been "restricted" was when I took my GREs (no calculators allowed) and when I took the Engineer Licensing exam (No graphing calculators allowed). I had an 86 in my SAT days, so I dunno about that case.
the Ti-83 plus but if you need to get one, do not get the Ti-89, get the Ti-84 plus silver edition, its the most user friendly graphing calculator out there. the Ti-89s are too hard to learn.
Ti-89 Titatnium. I love it since I can just let it any solve equations for me. It turned out to be pretty useful back in Algebra II, Calc, physics, and when I took the SATs.
I use a TI-83+Silver Edition. I wish symbolic would be updated so it could integrate though. Then I really wouldn't even want an 89. Nvm, I would. I just wish it wasn't outlawed in my Calculus class.
I'm in university and have not even been allowed to use a calculator in any class so far (CSE 191, MTH 142, MTH 309). I have the TI-89 Titanium but I don't need it anymore.
I just have an average scientific calculator TI-30X II S. I am only a freshman in High School and I only really need it for my Cosine, Sine, and Tangent ratios.
