\frac{3 \pi}{4} < a < \pi

, then

\sqrt{\operatorname{cosec}^2 \alpha+2 \cot \alpha}=

View answer and explanation

Correct option: C

-1-\cot \alpha

Option C (

-1-\cot \alpha

) is correct because within the given range for

\alpha

1 + \cot \alpha

is negative, so the square root evaluates to the negative of that expression.
