NAME
     sin, sinf, sinl - sine function

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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.
