Analyzing +4 | -1

\sin \alpha, \sin ^2 \alpha, 1, \sin ^4 \alpha

and

\sin ^5 \alpha

are A.P. where

-\pi<\alpha<\pi

, then

\alpha

lies in the interval

View answer and explanation

Correct option: D

None of these

Option D (None of these) is correct because the only value of

\alpha

that satisfies the given condition,

\alpha = \frac{{\pi}}{{2}}

, does not lie in any of the provided intervals.
