39 41 *
40 42 * Method.
41 43 * Let S and C denote the sin and cos respectively on [-PI/4, +PI/4].
42 44 * 1. Assume the argument x is reduced to y1+y2 = x-k*pi/2 in
43 45 * [-pi/2 , +pi/2], and let n = k mod 4.
44 46 * 2. Let S=S(y1+y2), C=C(y1+y2). Depending on n, we have
45 47 *
46 48 * n sin(x) cos(x) tan(x)

54 56 * Special cases:
55 57 * Let trig be any of sin, cos, or tan.
56 58 * trig(+-INF) is NaN, with signals;
57 59 * trig(NaN) is that NaN;
58 60 *
59 61 * Accuracy:
60 62 * computer TRIG(x) returns trig(x) nearly rounded.
