    Hiya,

    Could use some help. I'm looking to buy a graphical calculator (I'm studying A level and would like something better than my fx-83ES) and it's gonna be one of these three models (or any other suggestions :-P) (oh and it can't have CAS!):

    http://www.amazon.co.uk/Texas-Instru...3858186&sr=8-1 (£40)

    http://www.amazon.co.uk/Texas-Instru...pd_cp_office_1 (£75)

    http://www.amazon.co.uk/Ryman-FX-975...sr=8-3-catcorr (£49)

    Which one do you think is the superior model. Would it be better to stick to a cheap TI model because of their world-wide use (and if so - which TI model the 82 or 83 plus) or use the Casio model which has the advantages of USB hookup.

    Any help is appreciated

    I've come to the conclusion that graphical calculators are a waste of money. They're unnecessary and provide no advantage at A level, and if you do Maths at University you certainly won't be able to use it (if you're even allowed to use a calculator at all... at my University even the simplest calculators were prohibited in all exams).

    Even if you get to an advanced enough level where you want generated graphs, you'll use mathematical software (such as Maple or Mathematica) to do it, so your calculator will be redundant.

    So my suggestion would be to use your money for something worthwhile!

    I agree, but they're still cool and useful at times. I've got te fx-9750ga plus (bought it off eBay us new for £20 incl delivery). I just love watching it sketch polar equations. I know that's sounds nerdy but it gives u something to do in a borring maths lesson.

    I'm very happy with my calculator. If the one quotes above is similar I would recommend it.

    I've got a TI-84. It's pretty rad. Being able to check numerical integrations, differentiations, and check graph sketches is really a useful thing. TI-84 has USB hookup, plus you can get lots of games for it if Tetris in maths lessons is your thing (just remember to wipe programs before exams). It's pretty much the same as the 83 except for USB + more RAM, so go for the TI_83 if you are stumped for cash. Don't know much about Casio calcs. though (other than the classic fx-83).

    Hmm...The Casio one is similar - I might have to consider it.

    Hmm...Then again these two are TI fans. I looked and the TI84 is only £3 more than the TI83 plus so I may go for that...

    Hmm... It's between the Casio or the TI84 :-P

    Thanks for the help so far! It's been useful although any other comments are appreciated.

    My friend has a Texas instrument (dunno which one) and it's really messy to use. The screen clarity isn't good at all.

    I love my calculator even more now as just realised it can do complex numbers too. My screen is also very clear.

    sorry to dissapoint u but my casio can do the same apart from tetris. I can connect to the computer too. My one can also do complex numbers, matricies…

    And the best thing about it is, I got it for £20 new in box.

    Well mine can do these also: I suspect they have pretty much the same feature set. But there's more support/programs written for TI stuff, which is why I went for that. Just my preference.

    Hmm...for me I wonder if the extra support cancels out the £30 extra :-S

    I'd go for the cheapest option. The ones listed will each be able to do all the necessary things you need and there is no point buying a super-calc if you don't know how to use half the functions.

    It doesn't. I went for a TI mainly because I knew that they were a classically reliable type thing, whereas my past (though cheaper) Casio calcs tend to last a year or so before conking out. But that's kinda my prejudice: go for the cheaper one probably.

    I have a TI-83 calculator and I agree it's very useful. If price is an issue keep looking on eBay and the like because I got mine for £30 and it was practically mint condition. Came with a hookup cable and everything so yeh it's a real bargain if that's what you are looking towards.

    I would still use the FX-83ES just for the natural display input methods, unless you can do that on the TI-83 (Not sure because I just got mine recently).

    I second those who say you are better off saving your money. You can find free software which is both more useful and more powerful than any graphical calculator.

    I have the last one, which is pretty good. I mainly just use my non-graphical Casio natural display calculator though <3.
