By getting high enough grades, I got my mom to agree to buy me a calculator to upgrade from my TI-86. So what calculator should I buy? Currently I'm in math 252 (calculus 3rd semester), and I plan to continue studying calculus. I consider myself to be technologically proficient and I am willing to spend some time learning to use a good calculator.

I think my budget is about $200. 2.

It is a Casio CFX-9850GB Pluss and I would recomend it to anyone, especially someone in your situation of looking to delve deaply into the wonderfully deap and complex world of calculs. It can even approximate any number in Eulers Defribulation Series up to 10 decimal places! (You'll understand this when you get into 4th year probably.) It does take a little learning, I recomend a short course at your local college to get you up to speed with the basics. I think they retail for around$US125 but well worth the  for this baby ! Enjoy!

I like my TI-89.

My Ti-89 got me through high school calculus and helps serve as a check for the college courses I've taken.

Way better than the Ti-86 I had.

The TI-89 is probably the most obvious calculator, but can anyone elaborate on why I should choose it over similarly priced calculators made by different companies?
It would be great if someone who's used a few different calculators in advanced calculus would comment.

Well, you probably won't be allowed to use a hand calculator on a test anyway. For \$200 you can probably get a student copy of Mathematica for your PC.

i used a Ti-89 in highschool.. and now i'm using an HP49G+

the hp is quicker (it seems), has a much nicer screen and personally, i just like it better

i cannot comment on the functionality, since i dont have the TI to compare with now and i suppose it should be obvious, but i am now using the HP to do much more complicated things than the TI... so my opinion may be slightly skewed

it may be a bit out of your price range, but it is a good buy.. the only thing that i dont like about it is the keyboard, it can be a bit of a pain to get used to

I can't compare either, but my TI-89 is all I've ever needed.

The symbolic math functions are very powerful, entering matrices and other information is a snap, and I like that it keeps such a long buffer (30 problems).

If only I could teach it to make me coffee in the morning...
