CAS Software?

[bucket]

Well, It appears I've left my calculator at school, and I have my first SAC on Monday  :buck2:
Does anybody know any programs which can work like a CAS calculator?

No, I think it would be quite hard to find an emulator for the CAS, so you're probably better off hoping that you already know how to use your calculator. If the topics aren't particularly CAS-intensive, just grab your scientific calculator for basic calculations, and revise the topics that your SAC is on.

What functions (of your CAS) do you need? It might be easier to find particular programs online, if you really need it.

Something that could find the exact value of something like .

[Collin Li]

Can't you just save that for the exam? I mean, you know how to plug that into your calculator right? Just try to simplify things as much as you can, I guess.

Mmm well I could, the problem is the answers are expressed as exact values at the back of the book, so I wouldn't really know if I were doing the questions properly.
Thanks for the help anyway coblin.

Well, what you could do is type in the exact value from the answer (into your scientific calculator), and compare it with what happens when you type in into your calculator. You should get the same number, even though you only get an answer in decimals.

Dan15 found something that works like TI-89 (yes, I'm a 1337 lurker/file retrieval system)
