k_tan.c	18 * Input k indicates whether ieee_tan (if k = 1) or -1/tan (if k = -1) is returned. 21 * 1. Since ieee_tan(-x) = -ieee_tan(x), we need only to consider positive x. 23 * 3. ieee_tan(x) is approximated by a odd polynomial of degree 27 on 29 * |ieee_tan(x) 2 4 26 | -59.2 33 * Note: ieee_tan(x+y) = ieee_tan(x) + tan'(x)*y 34 * ~ ieee_tan(x) + (1+x*x)*y 35 * Therefore, for better accuracy in computing ieee_tan(x+y), let 43 * tan(x) = ieee_tan(pi/4-y) = (1-ieee_tan(y))/(1+ieee_tan(y)     [all...]
