(Space)Time for a Giveaway!

"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."

We're back with more copies of SpaceTime 3.0 to give away! Just like the contest that was held in May, we have one all-platforms license and two platform-specific licenses up for grabs. And, as always, the rules are simple. We've adopted a back-to-school theme for this contest, so to be in the running, simply make a post in this thread telling us how you'd use SpaceTime in an educational setting (or a commercial setting, if you're not a student or academic), and also the answer to "cos (0 degrees)", because we know you love number crunching.

You have until 11:59am (GMT) on Monday, September 1, 2008 to get your entries in. Winners will be announced the following week. Good luck!
