C sin() function - Calculate Sine

Syntax:

The sin() function is used to calculate the sine of x, with x expressed in radians.

Parameters:

Return value from sin()

• This function returns sine of x.

Example: sin() function

The following example shows the usage of sin() function.

#include <math.h>
#include <stdio.h>
 
int main(void)
{
   double x, y; 
   x = 1;
   y = sin(x);   
   printf("sin( %lf ) = %lf\n", x, y);
   x = 0;
   y = sin(x);
   printf("\nsin( %lf ) = %lf\n", x, y);
}

Output:

sin( 1.000000 ) = 0.841471

sin( 0.000000 ) = 0.000000
