Found this new feature by Wolfram Alpha. It's really neat.

If you forget how to solve an equation, or get zeros, or probably anything math related, ask Wolfram Alpha. It now does this neat step-by-step thing. Quite cool.
Not that it is useful for robotics (we just want answers), but it could prove useful for getting that extra help for Math when there is no one to help (though you're in robotics so you're a) never alone and b) never surrounded by someone who doesn't know math).
