maths software

I need a good software which can sketch graph and more.
What do you use?

Two suggestions.

TableCurve 2D and TableCurve 3D at:
http://www.systat.com/products/

Origin at:
http://www.originlab.com/

I just got origin.

How to sketch modulus function? I did not read the manual. later if I have time. I just need to know to work for now.

Well, I'm afraid I can't help you as I don't use Origin myself. It's a colleague of mine who's using it at times and whom I've heard praise it. Unfortunately I can't ask her for she's currently on vacation.

I played around with it for awhile and found it.
If your data are in column A and you want, say, modulus 2, you go to Column/Set column values and type:

mod(col(A),2)

thx very much...

I ahve a modulus question, wanna try? :P

Perhaps I'll have a go at it.

Use MatLab. Great software for mathematical computations.:p
