Syntax

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

Parameters

x

(IN) Specifies the argument whose sine is to be computed.

Return Values

The sin function returns the sine value.

Remarks

The sin function computes the sine of x (measured in radians). A large magnitude argument can yield a result with little or no significance.
