Why does it subtract 1, and why does it only work for values between [-1,1] ?
Furthermore why does cos take so much longer to calculate than sin when cos is just sin(x+pi/2)?

BECAUSE WHEN SIN IS SLOW COS IS FAST, AND WHEN COS IS SLOW SIN IS FAST.

IF YOU WANT TO CALC SIN AND COS USE FSINCOS INSTRUCTION OF THE MATEMATIC COPROCESSOR TO CALC BOTH AT COST OF ONE!

>>2
CALC BOTH AT COST OF ONE!
then why dowes sin or cos take like 37 cycles and fsincos like 50 cycles (overhead may apply)?
BUT, you are right, fsincos is faster than sin and cos individutally but SIN alone or COS alone is FASTER! NOT BOTH COST OF ONE!
