SIN(3)                DragonFly Library Functions Manual                SIN(3)

NAME
     sin, sinf, sinl -- sine functions

SYNOPSIS
     #include <math.h>

     double
     sin(double x);

     float
     sinf(float x);

     long double
     sinl(long double x);

DESCRIPTION
     The sin() function computes the sine of x (measured in radians).  The
     sinf() function is a single precision version of sin().  The sinl()
     function is an extended precision version of sin().  A large magnitude
     argument may yield a result with little or no significance.

RETURN VALUES
     The sin(), sinf() and sinl() functions return the sine value.

SEE ALSO
     acos(3), asin(3), atan(3), atan2(3), cosh(3), sinh(3), tan(3), tanh(3)

STANDARDS
     The sin() function conforms to ANSI X3.159-1989 (``ANSI C89'').

HISTORY
     A sin() function first appeared in Version 1 AT&T UNIX.
