What is the value of \sin^2 \theta \cos^2 \theta(\sec^2 \theta+\csc^2 \theta) equal to?

Explanation

Simplify the bracket: \sec^2 \theta + \csc^2 \theta = \frac{1}{\cos^2 \theta} + \frac{1}{\sin^2 \theta} = \frac{\sin^2 \theta + \cos^2 \theta}{\sin^2 \theta \cos^2 \theta} = \frac{1}{\sin^2 \theta \cos^2 \theta}. Multiplying this by the outside term \sin^2 \theta \cos^2 \theta gives 1.
