606 * kernel sin function on [-pi/4, pi/4], pi/4 ~ 0.7854
612 * 1. Since sin(-x) = -sin(x), we need only to consider positive x.
614 * 3. sin(x) is approximated by a polynomial of degree 13 on
617 * sin(x) ~ x + S1*x + ... + S6*x
620 * |sin(x) 2 4 6 8 10 12 | -58
624 * 4. sin(x+y) = sin(x) + sin'(x')*y
625 * ~ sin(x) + (1-x*x/2)*y
630 * sin(x) = x + (S1*x + (x *(r-y/2)+y))
689 * since cos(x+y) ~ cos(x) - sin(x)*y
890 * Let S,C and T denote the sin, cos and tan respectively on
895 * n sin(x) cos(x) tan(x)
904 * Let trig be any of sin, cos, or tan.
