With no division it is slower (?)

Very interesting. Looks like sin is faster for arguments less than pi/4 (~=0.7853981633974483):

Edit: "Intel's sin/cos implementation sucks golfballs through gardenhoses for arguments outside of [-pi/4,pi/4]": http://stackoverflow.com/questions/523531/fast-transcendent-...
