Allowed Calculator? Casio CFX-9850G for Exams

Hi,

I've searched through all the Edexcel and JCQ websites looking for officially allowed and banned calculator lists. Whilst Edexcel were useful in providing guidelines (no symbolic algebra and no stored programmes) the JCQ website felt more like a big comic book (typical of the Government!)

Anyway, I have a Casio CFX-9850G and have recently started using it for A-Level further maths. The graphical features are extremely useful and save much time. Therefore, I was wondering if anyone knew if I was allowed to take this into an official Edexcel exam. Apparently graphical calculators are allowed, but I just want to make sure this calculator doesn't have any other banned features. I wasn't aware of any symbolic algebra features but I have only just started using it and may have missed that button. Obviously the memories would need to be cleared of any stored programmes beforehand.

Thanks
IanR

surely your maths teacher... or the head of maths in your sixth form should be able to tell you..

and if they cant, i doubt the exam invigilators will have any clue... so i dont see that there would be a problem

I have it and have used it in exams before so I guess it's allowed. The entire class has one. It's not capable of symbolic algebra.

Yes it is allowed, and makes FP1 graph sketching ridiculously easy, along with a few other areas (generally its good for checking your answers, since you need to show all your working anyway)

Isn't C1 the only exam that specifies you cant used a calculator. I'm not sure, might be different on your board.

Besides it will say on the past paper, get one from your teacher.

thank you!

Hi, seeing how this is simlar i won't start a new thread.

Could anyone tell me the difference between these?

Casio FX9750G+
Casio FX-9750G PLUS
CFX9850GC+ Colour
CFX 9850GC PLUS

They all look so similar and and the names are so similar. What is the difference between the 'plus' and '+' ones?

Also for graphical calculators in general, can they plot polar co-ordinates?

My new calculator is called

CASIO Power Graphic fx-7400G PLUS

it said on the packing that it was 'Ideal for A-Levels and GCSE'
but one of the functions is 'Program' and another is 'Link' (Transmit/Recieve)

So it would seem to me that CASIO's packing was wrong? Or is this okay?

I have the same calculator as the OP (affectionately known as the black brick...the newer ones are the green/blue and white things). Yes they are allowed.
Apparently there are programs you can install to do symbolic algebra and stuff on them, but as you have to reset your calc in the exam hall before the exam, it doesn't really matter.
One of the functions on the CFX-9850G is Program and another is Link too, I just don't use them. (personally, I think it's a bit much for GCSE, very handy for A-levels though).

Yes mine can do polar co-ordinates. I've only figured out the basics so far, but I'm sure fancier stuff can be done. (the manual is beasty!)

And for the person who asked what else they can be used for - Stats. Lot of handy functions that I can't remember, but very useful. Also for iteration formulae you don't have to keep typing it in. Errrm, and on the "Table" you can whack in a formula and get all the answers you want - quicker than doing it manually on a scientific. It can also solve simultaneous equations as well as quadratic and cubic....
yea, it's kinda handy. especially as I *always* make mistakes adding...*looks embarrased*...

Yes, you can take that graphical calculator into an exam and use it without any problems. The only calculators you're not allow are ones which can do algebraic manipulation and algebraic differentiation/integration (basically those which have a CAS).

Basically, from that list you only have two Casio graphical calculators: the 9750G+ and the 9850GC+... There is, however, differences between these two calculators. You can find more on these two calculators at Casio's website here (9750G+) and here (9850GC+).

As for polar co-ordinates, I'm not sure about the Casio ones, although I know for certain that all currently available TI graphical calculators are able to, so I'd suspect the Casio ones can too.

This is fine, don't worry about it... Your calculator most certainly can be used in A-Level exams. The only thing is that you will be required to clear the memory of your calculator before you start the exam, that's providing you create/save any programs.

for the casio 9850G plus, how do u get grids on the graphs...and number the scales?
and when u draw up a table for a function can u program it so it can tell u where it meets the coordinate axis, instead of putting in ur own range of values?

Hello, I bought the Casio power graphic fx-7400G PLUS calculator because it was the only one i found whilst out looking.

I wanted one because it will allow me to check answers for definate integrals but it appears this one doesnt do that.
Is this correct? :frown:

very annoying
Thanks
