Prototype

double sin(double x);

long double sinl(long double x);

Description

Calculates sine.

sin computes the sine of the input value. Angles are specified in radians.

sinl is the long double version; it takes a long double argument and returns a long double result. Error handling for these functions can be modified through the functions _matherr and _matherrl.

Return Value

sin and sinl return the sine of the input value.

Example

#include <stdio.h>
#include <math.h>
int main(void)
{
   double result, x = 0.5;
   result = sin(x);
   printf("The sin of %lf is %lf\n", x, result);
   return 0;
}
