\sin \theta+\operatorname{cosec} \theta=2

, then

\sin ^n \theta+\operatorname{cosec}^n \theta

is equal to

View answer and explanation

Correct option: A

Option A (2) is correct because if sin(theta) + cosec(theta) = 2, then sin(theta) = 1, and therefore sin^n(theta) + cosec^n(theta) = 1 + 1 = 2.
