Behold, the trigonometric dad joke that makes calculus professors giggle uncontrollably during office hours! The punchline works because sin(θ)/cos(θ) = tan(θ) in trigonometry. It's the mathematical equivalent of finding that one student actually did the reading—pure, unexpected joy. Next time you're struggling with trig identities, just remember: they're not just formulas, they're ammunition for the nerdiest pickup lines in history.
