Revealing mistake

I love when equations in movies, comics or adverts actually make sense. All too often they are nonsense and reveal that whoever drew them did not even look into an ordinary textbook. Here is an advert where things are almost right (found via scaryideas.com) that I find pretty amusing. (click to magnify)

The equations on the nail are correct, but written in LaTeX. The advertising agency did check in some textbook, but actually wrote out the typesetting language rather than the equations as they would look in print. While I can imagine someone using the caret instead of superscript to fit a formula on a line, nobody writes "\cos x". Unless of course the exam the nail is intended to cheat is an LaTeX exam.
