That night, instead of working, he searched online: Answers for No Joking Around Trigonometric Identities . He found a blurry image from two years ago—same worksheet, different school. He copied every line.

“Due Friday,” she said. “No joking around.” Answers For No Joking Around Trigonometric Identities

“You didn’t memorize steps. You reasoned .” She handed back his paper. “Next time, trust your own brain instead of someone else’s answer key.”

He stood at the board, chalk in hand, sweating. He wrote (\frac{\sin x}{1+\cos x} \cdot \frac{1-\cos x}{1-\cos x}). Then (\frac{\sin x(1-\cos x)}{1-\cos^2 x}). Then (\frac{\sin x(1-\cos x)}{\sin^2 x}). Then (\frac{1-\cos x}{\sin x}). Then (\frac{1}{\sin x} - \frac{\cos x}{\sin x} = \csc x - \cot x).
