SINCOS(3)	       FreeBSD Library Functions Manual		     SINCOS(3)

NAME
     sincos, sincosf, sincosl -- sine and cosine functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     void
     sincos(double x, double *s, double	*c);

     void
     sincosf(float x, float *s,	float *c);

     void
     sincosl(long double x, long double	*s, long double	*c);

DESCRIPTION
     The sincos(), sincosf(), and sincosl() functions compute the sine and
     cosine of x.  Using these functions allows	argument reduction to occur
     only once instead of twice	with individual	invocations of sin() and
     cos().  Like sin()	and cos(), a large magnitude argument may yield	a
     result with little	or no significance.

RETURN VALUES
     Upon returning from sincos(), sincosf(), and sincosl(), the memory
     pointed to	by *s and *c are assigned the values of	sine and cosine,
     respectively.

SEE ALSO
     cos(3), sin(3),

HISTORY
     These functions were added	to FreeBSD 9.0 to aid in writing various com-
     plex function contained in	ISO/IEC	9899:1999 (``ISO C99'').
