Efficient Sine Computation

Efficient sine function computation approximation, 3*16 table can be reduced to 1*16 or 1*8 by cos/sin mutual transformations, and sample point region mirroring. The formula is the same as physics location change for speed and acceleration, ie, p=s+vt+½at^2, where s=location, v=speed, a=acceleration, t=delta-time.
