trig(3M) trig(3M) NAME sin, cos, tan, asin, acos, atan, atan2 - trigonometric functions SYNOPSIS iinclude double sin (x) double Xi double cos (x) double Xi double tan (x) double Xi double asin (x) double Xi double acos (x) double Xi double atan(x) double Xi double atan2 (y, x) double x, Yi DESCRIPTION sin, cos, and tan return, respectively, the sine, cosine, and tangent of their argument, which is in radians. asin returns the arcsine of x, in the range -1t/2 to x{l. acos returns the arccosine of x, in the range 0 to 1t. atan returns the arctangent of x, in the range -x/2 to x{l. atan2 returns the arctangent of ylx, in the range -1t to 1t, using the signs of both arguments to determine the quadrant of the return value. RETURN VALUE sin, cos, and tan lose accuracy when their argument is far from zero. For arguments sufficiently large, these functions return o when there would otherwise be a complete loss of significance. In this case a message indicating TLOSS error is printed on the standard error output For less extreme arguments, a PLOSS error is generated but no message is printed. In both cases, errno is set to ERANGE. 1 February, 1990 RevisionC
trig(3M) trig(3M) H the magnitude of the argument of asin or acos is greater than one, or if both arguments of atan2 are zero, zero is returned and errno is set to EDaM. In addition, a message indicating DOMAIN error is printed on the standard error output. These error-handling procedures may be changed with the function matherr(3M). SEE ALSO matherr(3M).
