Here’s the story, as you requested: No Joking Around chalk in hand

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). Answers For No Joking Around Trigonometric Identities

From that day on, he never searched for “answers” again. He became the kid who said, “Let me prove it.”

Leo blinked. “Wait… I did?”
