It's not that I don't love you guys... it's just hard to post (for some reason, my 6am brain wrote "poast" first... and I thought it was right - I must be hungry for some tost) these days.

For some reason it takes ~8 seconds to load pages on your rails app. I think you need to use FastCGI.

I'm on shared hosting (dreamhost), and I've tried to make sure that I've got it using FastCGI, but for some reason it occasionally acts like it's totally not... :\

Do you want the average absolute value of cos(theta), instead of just the average cos(theta)?

Yes, that's what I meant (or equally useful, the average of cos^2(theta)).

[mmcirvin]

Integrate cos^N theta times area of unit S^(N-2) from zero to pi, then divide by area of S^(N-1).

I think.

I used to know what the area of S^N was back when I was in Sidney Coleman's field theory class. Now I don't but I think you can look it up.

No, no, that can't be right.

That cos^N theta should be cos^2 theta * sin^(N-2) theta. Can't ever be negative.

Uh, maybe.
