34 36 * Table look-up algorithm by K.C. Ng, November, 1989.
35 37 *
36 38 * kernel function:
37 39 * __k_sinl ... sin function on [-pi/4,pi/4]
38 40 * __k_cosl ... cos function on [-pi/4,pi/4]
39 41 * __rem_pio2l ... argument reduction routine
40 42 *
41 43 * Method.
42 44 * Let S and C denote the sin and cos respectively on [-PI/4, +PI/4].
43 45 * 1. Assume the argument x is reduced to y1+y2 = x-k*pi/2 in
44 46 * [-pi/2 , +pi/2], and let n = k mod 4.
45 47 * 2. Let S=S(y1+y2), C=C(y1+y2). Depending on n, we have
46 48 *
47 49 * n sin(x) cos(x) tan(x)
48 50 * ----------------------------------------------------------
49 51 * 0 S C S/C

55 57 * Special cases:
56 58 * Let trig be any of sin, cos, or tan.
57 59 * trig(+-INF) is NaN, with signals;
58 60 * trig(NaN) is that NaN;
59 61 *
60 62 * Accuracy:
61 63 * computer TRIG(x) returns trig(x) nearly rounded.
