sin(), sinf()

Calculate the sine of an angle

Synopsis:

#include <math.h>

double sin( double x );

float sinf( float x );

Library:

libm

Description:

The sin() and sinf() functions compute the sine (specified in radians) of x. An argument with a large magnitude may yield a result with little or no significance.

Returns:

The sine value.

Examples:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>

int main( void )
  {
    printf( "%f\n", sin(.5) );

    return( EXIT_SUCCESS );
  }

produces the output:

0.479426
