Mathematics

This is about recognizing that two expressions are really the same thing in disguise—a classic identity verification. The key insight is to multiply the two fractions together and see what happens: if their product equals 1, they're reciprocals of each other, which proves they're equal. Alternatively, you can cross-multiply and use the Pythagorean identity $\sin^2\theta + \cos^2\theta = 1$ to show both sides lead to the same true statement.
