I love nerdy humor... there are some more jokes at the website, but this one's my favorite.

I like the Riemann sum one.....hehhehheeh....oh the joys of math....

I'm a sucker for these things.

lol, thats great, thanks for sharing

I don't know enough math to understand them all, but some of those are awesome :o).

Since distance equals velocity times time, let's let velocity or time
approach infinity, because I want to go all the way with you

This is gold I tell you.

actually number 8 is wrong. just because an equation is concave up doesn't mean it is increasing. concavity is the 2nd derivative and whether its increasing or not is the first derivative. wow that sounded really nerdy.
