In case you're wondering...

  $ gcc -o yanim yanim.c -lm
  yanim.c:1:1: warning: data definition has no type or storage class [enabled by default]
  yanim.c: In function ‘main’:
  yanim.c:5:24: warning: incompatible implicit declaration of built-in function ‘cos’ [enabled by default]
  yanim.c:5:33: warning: incompatible implicit declaration of built-in function ‘sin’ [enabled by default]
