Syntax

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

sin calculates the sine of x, with x expressed in radians. If x is too large, a partial loss of significance in the result may occur.

sin returns the value of the sine of x.

This example computes y as the sine of pi/2.

#include <math.h>

int main(void)
{
   double pi,x,y;

   pi = 3.1415926535;
   x = pi/2;
   y = sin(x);
   printf("sin( %lf ) = %lf\n", x, y);
   return 0;
