31 32 * sinl(x)
32 33 * Table look-up algorithm by K.C. Ng, November, 1989.
33 34 *
34 35 * kernel function:
35 36 * __k_sinl ... sin function on [-pi/4,pi/4]
36 37 * __k_cosl ... cos function on [-pi/4,pi/4]
37 38 * __rem_pio2l ... argument reduction routine
38 39 *
39 40 * Method.
40 41 * Let S and C denote the sin and cos respectively on [-PI/4, +PI/4].
41 42 * 1. Assume the argument x is reduced to y1+y2 = x-k*pi/2 in
42 43 * [-pi/2 , +pi/2], and let n = k mod 4.
43 44 * 2. Let S=S(y1+y2), C=C(y1+y2). Depending on n, we have
44 45 *
45 46 * n sin(x) cos(x) tan(x)
46 47 * ----------------------------------------------------------
47 48 * 0 S C S/C
48 49 * 1 C -S -C/S
49 50 * 2 -S -C S/C
50 51 * 3 -C S -C/S
51 52 * ----------------------------------------------------------
52 53 *
53 54 * Special cases:
54 55 * Let trig be any of sin, cos, or tan.
55 56 * trig(+-INF) is NaN, with signals;
56 57 * trig(NaN) is that NaN;
