i got a casio calculator fx 7400g plus calculator and i wanna add sum programs for maths on it. I am doing pure 3 now ( mei structured maths) and the first chapter is well hard. its all about simplifying equations. i was wondering if any of u guys know any programs i can add on my calculator to make it easier for myself. if u know any site or things that my benifit for my calculator let us hear.
cheers

No, it's an entirely separate program for your PC.

Incidentally, if you're doing MEI (as I am) you won't be able to use programs on your calculator in the exams to solve the equations, so why not avoid falling into the habit in the first place?

I haven't started P3 yet (I'm doing AS-Level).

I suspect there are, programs - but I wouldn't risk it. They're more strict at my school, i.e. checking calculators for programs which shouldn't be there at the start of exams.

i have that calculator... i have no idea how to work it *can do me sums + draw graphs, but gets kinda lost after that*

you can add programmes to it- my friend is a computing whizz and he has managed to put all the equations you needs for A level (cept P2 cos it not allowed) on his, all he has to do is put in a= , b = etc. it's not allowed, but they don't check.

I got it as well but I hardly use it. I would love to be able to draw these weird graphs you see on the box though. I saw some flower being drawn once.

Yes i got one and loved it till i got the model above which does far more, i dont like the 7400 as it doesnt do stuff like intercepts solving quadratic equations, numerical differenciation/integraction, recurrence relations, circles, but i liked it, i used it for my GCSEs but now i'm doin P3 i like sumthing more advanced, it makes life really simple, i find shortcuts in almost all modules. Unfortunatly it cannot do algebra, though my dad has a calculatro which can I think its a Texas Ti 89, that is really cool it does loadsa algebra + 3d graphs and tons more but i cant afford £100 yet.

Also, you cant program your calculator for an exam, that is cheating.

Also have you used mathematica or MathCAD or Maple, they all do hugley complex mathematical things on computer, they are really fun, like if u happen to want to know what 300! is. lol, or maybe its just me whose sad.

You are not allowed to use graphical calculators for P3 (or P1), for these exams there is a list of allowed calculators which contain most of the basic models but no programmable or graphics models. So you cant use them to help you out with graphs and things in these exams.

You can use graphical calcs for any other maths modules but must clear the memory, just like with any other calculator which means theres no point doing any programming.

BTW this is for edexcel - other boards may have different rules.

I think in OCR its only P1 where you cant use a graphic calculator.

IIRC, you are not allowed in any of the A-level maths modules or exam board a calculator which can perform symbolic algebra. Certain modules and boards allow graphical calculators, but I don't know of any which allow calculators with symbolic capability. The fx-7400G plus is the one usually recommended to A-level students as it doesn't have any symbolic capability, hence you will not be able to use it to do partial fractions or other such (non-numerical) operations.

I use a casio fx 9850 i find it better than the 7400, its about the most advanced before you get to symbolic ones, its really cool.
