So I'm taking this college algebra class, and the lady says I need to buy a TI-83 Plus. Will the TI-89 do everything the 83 will, and more? I'd rather not spend $100 for the 83 and have to buy the 89 a year later.
Need help buying a calculator.

A TI-83 Plus will be fine.....I just finished Calculus 2 in college and the calculator has done great for me
You shouldn't need the TI-89. I have the TI-86 and TI-83 and they were more than enough for two years of college math. (That is -- when they let you use calculators).

The TI-89 can do everything that the others can, plus much much more. I have both the TI-86 and TI-89, and I now hate using anything other than an 89. If you spend a little time learning how to use it, you'll soon discover that it can even do all the work for you (great for checking your answers as well mulitple choice tests (SAT)). The pretty print is also a very nice feature, more so than you realize until you use it. Copy/Paste is pretty nifty as well.
All in all, the TI-89 saves you a whole lot of time in the long run once you get past the initial learning curve. I strongly recommend it.

89's are not banned on the sat's. Your thinking of the 92 which has the qwerty keyboard. I would go for the 89, especially since it has much better games and comes with the graph link included.

You do NOT need the TI-89 unless you're planning to become an engineer or of related fields. I have a TI-86 and a TI-89 and have no use for my 89.

NO WAY the 89 is the best ever , if your gonna do any more math ever get the 89 its awsome, guys will be jealous and girls will swoon. and you can use it on any standerized test
while the 89 is an absolutely banging calculator, I must offer a word of warning. If you have never done any calculus before, DO NOT get this. I had one, and let my roomie borrow it to help him with his homework. It became a crutch for him, and when he couldnt use it on the exams, he failed. Now, I'm not saying that you will use it as a crutch, or will fail any exams, but I'm just lettin' you know that it has happened.

<< Be aware that 89's are banned for most standardized tests, include SATs and APs. >>
Another example of misinformation on the internet.
THE TI-83, TI-85, TI-86, and TI-89 are all ALLOWED on the SATs, APs, and most standardized tests.
The TI-92 is not.
Does the ti-89 have the unit conversion tables?
That's saved me so many times in engineering classes, I love it.

Just this year, my EE teachers totally banned all graphing calculators on tests. They said it is not fair to use because not everyone has one. I do not know a single person without one. What's the point of taking a circuits test in which you half the time is wasted converting from Rectangular to polar and vice versa. :|

You in college Ameesh? Keep in mind, most math classes won't even let you have any type of calculators when taking midterms or finals. My TI-89 is slowly collecting dust and my TI-86 is just used for simple calculations. MOST people who buy the TI-89 don't even know how to really use it. Like I said before. It was designed for engineers, period.

I've found that Calculators, Inc. has some of the best prices for TI, Casio, Sharp, HP, and other calculators (both scientific, graphing, and business) than many other vendors. Check them out and compare prices. That's where I got my TI-89. I also recommend scouring TI's website as well as ticalc.org for product information.
wQuay, to answer your question, of course the 89 will do everything the 83 will, and a heck of a lot more. It depends on how much math in college you're planning to take. For College Algebra, I wouldn't recommend getting the 89, because you will become dependent on its symbolic manipulation features and will not be as likely to have the motivation to learn how to do the calculations by hand.
On the other hand, if you're:
1) planning on taking lots of college math (calculus and beyond) and/or engineering
2) have the motivation to ONLY use the 89 as a checking tool and not a cheat sheet or crutch
3) have extra cash
then by all means get the 89.
I took a Calc 1 class last summer, and even though I had an 89, I still had to become acquainted with the 83 series because it was the only calculator allowed on exams. My 89 was futile. Although it helped me on the SAT and on homework, I had to learn the material by hand.
That's really what the purposes of calculators and computers are for. They're tools, not sex toys--I mean crutches. They're made to help you visually learn and get a better grasp of the material.
If you do plan on getting the 83 series, get the 83+ (with upgradeable Flash ROM and more memory) or the 83 Silver Edition, which just came out. Has a faster processor and other features. Honestly, if I wasn't getting an 89 and had to choose between the TI-83 series and another TI series, I'd get the TI-86 for sure. The screen has a much higher resolution (instead of 15 or 16 characters, it holds like 24 or something) and it uses a faster Z80 CPU, plus more memory for apps and games.

I agree with xyion. I would not recommend using an 89 before Calculus, because when you get to Calculus and have to do something without a calculator (even something simple like finding a derivative), you will be screwed if you have relied to heavily on the 89's features.
The TI-83 will do just fine for that. I used one in a similar course and it did everything I wanted it to.
just get the 89... you can get it brand new for like 100$ off of ebay anyways and its the best possible Texas Instrument calculator you can get thats not banned on any standardized tests... now of course if you're willing to learn new interfaces.. such as Hewlett Packard and Casio.. they make better calculators at cheaper prices... its just re-learning all the functions and what not can be a b*!ch..
Well, 89 it is then. The 83 + would probably be adequate, but I'm hoping to eventually become an engineer. I rarely use even a regular calculator, so I should be able to avoid becoming dependent on the 89's advanced features.
Thanks!
Thanks!
I absolutely adore my 89...I got it when I was a junior in HS (doing calc), two and a half years ago, and it's my baby. I wouldn't recommend anything else to anyone who will be doing calculus.
But as the others have said, DO LEARN THE CALCULUS. It sucks to get dependent on your calculator and then not be allowed to use it. (IB doesn't let you use the 89. sigh.)

yep, I second this. Learn the concepts and don't rely on the calc too much. At an engineering school some of my friends go to, they actually are not allowed any calcualtors (not even 4 function ones) for tests in the intro engineering math classes(single var calc, multivar calc, linear algebra, diffEQ) or the three semesters of intro physics(mechanics, E&M, optics, waves, etc.)-- and they don't make the tests easy either.
