"SpaceTime 3.0 by SpaceTime Mathematics is a revolution in mathematics software with 2D, 3D, and time graphing with MobileCAS® for algebra and calculus. With features only available in Mathematica and MATLAB, SpaceTime is the most powerful cross-platform mathematics software ever developed for computers and mobile devices."
I have been using this for years on my Pocket PC devices and now it is here for Smartphones. The graphing and plotting capabilities are worth the price of admission and there is a 30 day trial available. I have been using it on my Q 9h and really appreciate what Spacetime can do.
