MCQ
If $sin^{-1}\,\theta = sin^{-1}(sin\,5)$ then $\theta $ is
  • A
    $sin\, (5 -\pi )$
  • B
    $sin\, (2\pi  -5)$
  • $sin\, (5 -2\pi )$
  • D
    None

Answer

Correct option: C.
$sin\, (5 -2\pi )$
c
$ \sin ^{-1} \theta =\sin ^{-1}(\sin 5) $

$ \sin ^{-1} \theta =5-2 \pi $

$ \theta =\sin (5-2 \pi) $
