This may be off base, but id really love to track you down with a 30 rack and talk to you about a few things. I think I know how your feeling.
I use a Casio fx-991ES Plus. Mostly because it was designed to meet (and take advantage of) the rules that my A-Level exam board set. Its cheap and does what it needs to for my needs. I don't think I have seen a single TI calculator throughout my education, everyone seems to use Casio's and some people used Sharp's (). Although the calculator is hilariously bad for anyone with pretty much any type of colour blindness. they used all of the colours that you should not use and put them on a semi metallic background making them hard to see in bad lighting even for people with full colour vision such as myself. I also have a fx-83es. Which is pretty much what everyone used before the newer model of it came out, I moved to a higher end model to get some useful extra stuff such as numeric integration (algebraic was not allowed). Still works great, use it as a backup calculator. I guess I have also used OmniSolve on Windows CE 3.0 on an HP Jornada. It is pretty ok, it also does date calculations and financial stuff. The help documentation has a fun little comment at the bottom of its FAQ But calculators are not an area of expertise for me, although I have better understanding of the more advanced functions than most.
My school uses Casio FX-9860GII calculators for its math class. Really helps when you have to find stuff like compounding periods, rates of interest, present value, future value, so on...
Well lah-dee-http://media.beamng.com/UAZIXZqBMdDv62Ek-dah Mr. Rockefeller! You want one of those fancy participation awards since you require gratification every single moment in your life? Let me guess, now you're gonna feign mental disorders again so you can get more attention.
Yeah, well, I have TWO TI 83+s. The first is a really old model that broke then fixed itself right after I bought a new one.. The only button that would work was the on button, then about a month later when I tried it again it was working fine. --- Post updated --- Geez.
Some of you seem to still be in geometry based on your calculators... Calc 3 would be Hell without a proper graphing calculator.
I am a second year games computing (computer science with one module a semester swapped for games programming) university student and I have yet to see a graphing calculator in person. While they are (probably) very useful they are also expensive, more importantly for A-Level maths they are not needed. Not a single person at my sixth form (last 2 years of school before uni) had a graphing calculator including higher maths students. Maybe its just a UK thing but they don't seem to be all that popular over here.
He made a normal statement, and look at you. Just pissed at him talking about a calculator he has.. You sound like you want attention yourself.
I didn't realise it was possible for a (I assume) functioning human being to be so triggered by a calculator.
\ I also have the fx-991ES Plus. Just like my Prism, I love it. I never really noticed what you mentioned about the colours before until now, and it doesn't really bother me. As for graphing calculators, it seems that in North America almost everyone have TI's. TI's seem to be very outdated compared to other calculators, eh? Sure they can do a lot, but not more than most graphing calculators (at the TI-83/84ish level) from what I know at least. I also find that TI's are rather annoying to work with... I'm not biased at all... Also, the Prism has a built in periodic table with a bunch of information about elements which is useful for me. It's also for playing Gravity Duck, Pong (2 player), Battleship, etc. I even have a program to overclock it. Anyway, that's just what I know/my opinions...
There was a deal struck between ti and an education board in the states hence widespread adoption. Then teachers only knew how to operate ti devices and so no change from them was made. Graphing calculators were banned from British exam halls. Yes calc 3 is easier with one, you're not allowed though. I knew one guy that had one for a level maths and he could only use it to confirm answers.
I don't use it for calculus now, but for engineering dynamics and physics. We were not allowed to use one during the calculus tests
That's part of what makes Calc 3 so hard, is that you start messing with 3 dimensions instead of just your normal x-y plane. Graphing 3D, even on a graphing calculator, is difficult to read to find the information you need. There are several colleges (UW-Madison comes to mind) where the professors don't allow you to use a calculator at all.
