NAME
       sin, sinf, sinl - sine function

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       double sin(double x);

       float sinf(float x);

       long double sinl(long double x);

DESCRIPTION
       These functions compute the sine of its argument x, measured in radians.

RETURN VALUES
       Upon successful completion, these functions return the sine of x.

       If x is NaN, a NaN is returned.

       If x is +-0, x is returned.

       If x is +-Inf, a domain error occurs and a NaN is returned.

ERRORS
       These functions will fail if:

       Domain Error    The x argument is +-Inf.

		       If  the	integer  expression  (math_errhandling & MATH_ERREXCEPT) is non-zero, then the invalid floating-point exception is
		       raised.

USAGE
       An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before  calling	these  functions.  On  return,	if
       fetestexcept(FE_INVALID	|  FE_DIVBYZERO  |  FE_OVERFLOW  |  FE_UNDERFLOW) is non-zero, an exception has been raised. An application should
       either examine the return value or check the floating point exception flags to detect exceptions.
