SIN(3)                 FreeBSD Library Functions Manual                 SIN(3)

NAME
     sin, sinf, sinl - sine functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <math.h>

     double
     sin(double x);

     float
     sinf(float x);

     long double
     sinl(long double x);

DESCRIPTION
     The sin(), sinf(), and sinl() functions compute the sine of x (measured
     in radians).  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.
