Texas Instrument Calculator

I need help in choosing which TI model calculator to buy. I will be using it for algebra, statistics, pre-calc, & calc. I need it to be scientific & graphing. Anyone know which one will be useful for all the math classes listed.

Thanks
 
i was thinking of getting either the 86 or 89. If I get either of these does it have the same features + more if I get the newer models or does each model do everything seperate.
 
you don't even need a garphing calculator for those classes....but if you really insist you need one, the ti-83 plus should be more than what you need.
 
At the high school level, teachers are scared shitless of anything other than the 83+.

Calc teachers swear by the TI-89, but won't let you use it on the tests more often than not because, quite frankly, it can do everything for you.

Then again, if you know what you're doing, you can make the 83+ do almost all the work in Calc on there too.

yes....86 is wate of money though....if you get teh 86, you might as well spend the extra dough to get an 89.
 
I remember when I took algebra 1 (7th grade), my calc broke the night before the final so I had to use my sister's and it was some graphing problem that was really huge and I only had 7 minutes left, and I figured out how to work it and poof, I got the problem fully right.

So if you're in high school, and the teacher doesn't know what the 89 is, go for it.
 
regular old scientific calc should do the trick for those classes, our faculty standard calc is the Casio FX-991 and it's more than enough for exam-type stuff. For homework, you'll probably want something like Maple and Matlab for more flexibility and a bigger screen
 
I got an 89 when it was released five and a half years ago. I still have it, and I'm a third year engineering major.
 
I'd say look around for an 89 in the clearance aisles at local office supplies stores. They released a new one recently and are phasing the old one out. There might be a thread in hot deals here about it. I had an 86 all throughout my undergrad and I often wish I had an 89. On some tests and homeworks, I borrowed my roommates' 89 to help out. It has more features than an 86 and can do some really amazing things with calculus.
 
I used ti-83 plain from high school through college, and I didn't even take advantage of its full feature. I wonder what can a ti-89 do. too bad all my classmate used the 83 also so I never get to know the difference.
 
well, some teachers really don't like it if the whole class uses different calculators, so i would just go for whatever is most popular, because it's just like puting a windows user behind the wheels of a linux computer, or rather the keyboard of, because the calculators are so different.
 
I don't think most teachers would let you use 89's on tests (at least the ones I've experienced). I have an 86 and it's served me well. An 83 would be good also.

Yeah..Id ge tthe 83+ or 84, whatver..but beware if you get the 89..you most likely wont be allowed to ever use it on tests.
 
Check to see what you're allowed to use, most instructors will allow up to a TI-83/4 or equivalent. While a TI89 would be nice, you may be stuck without it on a test. I own a TI-84+ SE, I keep it in a leather case and I have coverings for the keys. 🙂
 
Ti-83+ would be fine, however its being superceded by the 84+, so its either pay a little more for a very good 84+ or get a good discount on an 83+.

Ti-89 would be great if your instructor allows computer-algebra calculators.
