So does this make our calculator be able to do simbolic algebra?

I fx 570 allowed ? It does integration.

How about CFX-9850 GC plus graphic calculator?

Is that allowed at Alevel exams?

No, the fx991ES does NOT do symbolic algebra, integration or differentiation. If it could do symbolic, it would be banned.

It's all numerical.

The fx570 is basically the 991ES without a solar panel, so yes it's allowed.

I have a 991ES but I still wish I could do this to my 83ES version B just for the fun of it. >.<

My Ti89 does symbolic, but it wasn't banned. I used it in my C2 exam last week.

:O

You big cheater.

I checked, and there's no AQA calculator restrictions. There were some tricky integration questions that took me seconds :smile:

. I could have done it by hand, but didn't want to waste time and the best thing is, that because it's symbolic I wrote down the stages to get the working marks.

There are AQA calculator restrictions.

All exam boards comply to the JCQ regulations.

Pfft, you big big big cheater.

Surely all exam boards comply with the JCQ (Joint Council of Qualifications) regulations?

Hey,

Would this mod work on a fx-82AU or a fx-500ES?

Thanks

Is the FX-991 ES not allowed for A-level exams? That's including Further Maths.

Yes, it's allowed for all A-level Maths exams as it does not do symbolic differentiation, integration or algebra. :smile:

you guys are lucky, for us symbolic includes surds and answers in terms of pi :frown:

That means we get a cut down version of this calculator called the fx-82au, its terrible!

what? your invidulators are not letting you use the calculator for those reasons? that's RUBBISH!

arrgh tell your school to tell the invidulators that it's allowed and show them the reasons why. it's in the schools BEST INTEREST to let you use it cos it makes the school look when more ppl pass

the 991ES saved me in my FP2 exam big style

Heh, wow. Thanks for the tip, I didn't think it'd work at all, but lo and behold...

Now I just need to see if I can work out how to use all these new functions, I've never even used a matrix or anything before, but hey. :smile:
