[Haskell-cafe] derivatives and integrals

Hi. The scope of this question is likely bigger that Haskell, but this seems like the right crowd to ask. I'm in Calc II right now, and I'm looking for a FOSS desktop application (I use Gnu/Linux) to replace the functionality of my TI-98 in finding derivatives and integrals. (It's very convenient for double checking my own solutions.) I've heard of some software like Octave, but the manuals are usually very large, and I'm not sure what is the best one to start with. I was wondering if there is anyone on this list who uses free software to do that sort of simpler Calc stuff, and what it is that they use. -- frigidcode.com
