sin 

Computes a sine value.

Syntax 

     #include <math.h>
     double sin (double x);

Parameters 

x             A real number measured in radians.

Return Value 

n             The sine of x measured in radians.

0             Indicates a complete loss of significance for large values
              of x.  A TLOSS error message is printed on the standard
              error output; errno is set to ERANGE.

Description 

The sin function loses accuracy when its argument is far from zero.  For
arguments causing partial loss of significance, a PLOSS error is
generated but no message is printed and errno is set to ERANGE.

Error-handling can be changed by a user-written matherr function.
