Okay, thank you all wrt the `-lm' flag!   :^D

I  have one more question... Why do you think the following program 
compiles,
links and runs fine, without using `-lm' on:

http://www.tutorialspoint.com/compile_c_online.php
____________________________________________________
#include <math.h>
#include <stdio.h>

int main()
{
    double v = cos(3.14);

    printf("v = %f\r\n", v);

    return 0;
}

I found this to be very strange because it works with:

gcc -o main *.c


However, this does not work on codepad:

Humm... I must be missing something again!
