Question : If $\theta$ is an acute angle and $\sin \theta+\operatorname{cosec} \theta=2$, then the value of $\sin ^5 \theta+\operatorname{cosec}^5 \theta$ is:
Option 1: 10
Option 2: 2
Option 3: 4
Option 4: 5
Correct Answer: 2
Solution : Given, $\sin \theta+\operatorname{cosec} \theta=2$ This is possible only when both $\sin \theta=\operatorname{cosec} \theta=1$ So, $\sin ^5 \theta+\operatorname{cosec}^5 \theta=1^5+1^5$ ⇒ $\sin \theta+\operatorname{cosec} \theta=1+1$ ⇒ $\sin \theta+\operatorname{cosec} \theta=2$ Hence, the correct answer is 2.
