Leo froze. His copied answer said: Multiply numerator and denominator by (1−cos x) . But he had no idea why.
Leo wasn’t bad at math, but he was lazy. When Mrs. Castillo handed out the worksheet titled “No Joking Around: Proving Trigonometric Identities,” Leo groaned. Sixteen proofs, all requiring (\sin^2\theta + \cos^2\theta = 1), quotient identities, and the rest.
Leo nodded, but his brain had already hatched a plan.

And he never joked around with trig identities again.
“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.”

The next morning, he turned it in, feeling smug.
Leo blinked. “Wait… I did?”
From that day on, he never searched for “answers” again. He became the kid who said, “Let me prove it.”
