Wolfram?!

If you're like me and made it thus far in your mathematical career without finding out about this website.. well... you're welcome. Wolfram (You really should just bookmark this. Right now.)

Examples: Forgot what onto or one to one means? How old the oldest recorded lion is in captivity? The series expansion of e^x is?

Feel free to add any more awesome pages!!

__Tips on how to use Wolfram__: Remember you can do things like integrals, limits, derivatives (if you need it for Calc or Analysis) - just always try to add ", x, from 0 to infinity" separated by commas. Usually it's pretty good about that kind of thing. I kind of forgot how to do matrices, but you can input it in one line - experiment!

Also if you just have NO idea what something "looks like" - input the equation into Wolfram and usually they will try to give you some visual rendering as well as other really useful information about it.

Also they have good definitions for terms, if you don't "trust" Wikipedia (or the Wikipedia article goes WAY over your head. Until I became a math major, I didn't realize that could happen.)
