Wolfram Alpha

Wolfram Alpha claims to be a computation engine, so it can tell us things about maths, apparently.

I heard it could 'compute' things, based on a huge database it had, so I needed to know the probability of something occuring, I thought I'd try out Wolfram Alpha. Needless to say, it returned nothing. I wasn't really supprised.

I though, ok, thats perhaps a bit obscure, perhaps I'll try a few maths-y terms from computer graphics and see how we go.
spherical harmonics, returned nothing. OK,.. perhaps a bit too obscure? (But Spherical Harmonics are described on their own website..)

How about the bitangent vector.. again, nothing. Wierd, again, there is information on the bitangent vector on the Wolfram website!

Clearly I'm asking for too much, so I tried the simple cross product. OK, I'm pretty sure this was covered in high school..

Exactly how stupid do your questions have to be before Wolfram Alpha gives you some information? dot product? No joy. vector at last! It knows something about maths... .. .

I'm sure it won't be long know before it achieves singularity.
