Calculator Graphing Calculators!

Recommended Posts

I was forced to buy a TI-84 Plus Silver but now I value it more than my Maths HL textbook (Although it is too complicated to use!)

To be honest, not having a GDC is surely a serious advantage.

Our school lends out TI-83's to all students from about Grade 9 upwards. You pay a $100 deposit and if you want to get your money back, you return it. If you need it for university, you can keep it. Works out pretty well, since $100 is cheaper than usual (my old one cost $110).

The TI's are also good value for money since they don't run out of battery very easily and also don't break. I have had mine for 2 years now, still haven't changed the battery and I'm forever dropping it on the floor. Not even a scratch.

What's the difference between the TI-84 and the TI-83? And does anyone know what is the most "sophisticated" calculator that you are allowed to use in exams, according to IB regulations? My friends in the French school have ones that include entire formulas and equations, I know that we aren't allowed to use them.

How exactly do you load programs (is it in the manual that I've never opened?) and where do you get the programs from? My teacher said she had one for quadratic equations, but since she's taking a year's leave now we can't get it from her.

Your calc should have come with some USB cable of sorts, which you can use to link it to your computer. Either that or some I/O to I/O cable which you can use to link two calculators together.

To send files, on the sender calculator go to (2nd function) Link -> Program -> (choose the program) -> send. On the recieving calculator go to Link -> receive. You have to put the receiving calculator on receiving mode before you send stuff on the other one, I think.

Thanks. Do you know where I can get the programs? Can I find them for free on the net, or do I need to know someone who already has them on their calculator?

You can just google: "[calculator type and edition like Ti-84, how to download free games". It's really simple.

I have a Ti-84 and we need one for IB regardless if we're taking SL/HL (we don't offer Math Studies anymore 'cause not enough people took it).

I don't think it's possible to pass Maths SL/HL without a graphing calculator. A lot of the questions in paper 2 can be easily solved with a GC, solving it by hand would be an immense waste of time (and possibly less accurate).

I have a TI-84 Plus.

LOL Without a graphing calculator.. you can not pass IB Maths..

hmm maybe you can pass studies without one, but i think you really should get one..

Im using the TI-83 Plus.. it's pretty good, at first I hated it but now I truly think it's one of the best calculators I've ever used.

mine doesnt, but they highly recommend it because it your in studies or methods, you are going to need it. So you are better off buying it unless you like doing graphing by hand

It is impossible to pass IB math (anything) without a GDC as some questions require you to specifically use GDC. Also even in Studies you would need it for stats etc. So buy one!

Keep in mind you shouldn't be too dependent on added on programs as you're not allowed to keep those in the exams but have to delete them. So just go with what your GDC gives you
