If

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

, the value of

\sin ^{10} \theta+\operatorname{cosec}^{10} \theta

is

View answer and explanation

Correct option: A

2

Option A (2) is correct because if

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

, then

\sin \theta = 1

, and thus

\sin^{10} \theta + \operatorname{cosec}^{10} \theta = 1^{10} + 1^{10} = 2

.
