Free math “book”

Yesterday, I migrated my personal math reference to the new Wiki:

http://math.chaoticpattern.net/wiki/index

It is all in German and with my own clumsy comments. Those who read it, will notice that math is a useful tool for me, rather than some kind of art – although I agree you can look at it as art, if you got the time. That’s why I tried to compress it as much as possible ;)
