Best Graphing Calculator

Another reason why I want the TI89..

I have a TI-83+ and I havn't found anything that it cannot do.

I'm only in Trig, but it has met my every need. What it didnt offer initially, I either A. found a program on the internet to do it for me or B. wrote one myself, I mean, its only BASIC after all :P

I bet when you get to the harder math the TI-89 makes it much easier, but for what I do the 83+ is fine.

(BTW, I love putting science notes in my calculator for test referencing )

^^ LMAO at youre awesome sig! i have a TI graphing calculator (forget which model, but its the one of the popular ones at most stores for $100) and it got the job done for me. now im ready to put it away and hope i never use it again.

I've gone through a TI-81, two TI-82's, two TI-83's, and a TI-92.

Basically, the only thing the 83 has over the 82 is that it can do imaginary numbers (if i remember correctly). But I'd get the 83. It does everything you need for HS and early college math. Once you get to some higher math classes (like Calc II and higher) then you may consider a more powerful calculator. In higher math classes, its nice to have a calculator that can do complex integrals and stuff because it saves time for more complicated problems. It's also a good homework checker because you can type in like 5th degree intergrals and it spits out the answer in a second

Well it's been a long while since I've even touched one of these things. The TI series were pretty popular when I was in high school. I ended up with a Casio(don't remember the model#, it was top of the line back then). It did what I needed it to. I did get a chance to play with a TI series and the functionality was not much different. I think the TI was a bit easier to use overall. Both had enough power to do some complex things. I wrote a small program to play blackjack on my casio. My friend made a Mortal Combat game(more like a very short movie) on his TI. About the biggest differences I found was that the TI was more flexible with multiple curves on one graph where you could plot several equations on the same graph and move between them. The Casio did one plot at a time, but could overlay on top of another graph. The disadvantage here was that you could not go back to the previous graphs to trace the curves. The Casio also used watch batteries which are expensive. And to top that off, it used them very quickly. The TI's used standard sized batteries and seemed to last much longer from what I remember.

if you plan on taking classes where a 92 would be needed, go with the 92 right off. No sense in buying a lower grade calc. and then needing to upgrade later on.

I know once you go to college, well at least a Georgia Tech and NCSU and NCCU. Ok I'm a huge dork and have taken math classes at all of these schools. Well anyways what I was saying is that the professor tell you that you cannot use a TI-89. However they dont say it that explictly. They say you cannot use a calculator that can do intagrals or derivits (obviously I prefer math) however they do not know anything about calculators and therefor they assume that only the keyboard style calculators have the abbility to do that. So if you are honest then you would not be allowed to use a TI-89 any more however I never had a problem using them for my classes between calc 1-3, Diff. Equation and statistics (the 89 also a lot of useful functions for statistics).

Sorry those schools are North Carolina State University, and North Carolina Central University.

I was also in Calculas the first year the ti-89 came out so I cannot vouch for the inteligance of profs any more.
