MCQ
If $‘n’$ is an integer, the domain of the function $\sqrt {\sin 2x} $ is
  • A
    $\left[ {n\pi - \frac{\pi }{2},\;n\pi } \right]$
  • $\left[ {n\pi ,\;n\pi + \frac{\pi }{2}} \right]$
  • C
    $[(2n - 1)\pi ,\;2n\pi ]$
  • D
    $[2n\pi ,\;(2n + 1)\pi ]$

Answer

Correct option: B.
$\left[ {n\pi ,\;n\pi + \frac{\pi }{2}} \right]$
b
(b) According to question, as $\sqrt {\sin 2x} $ can’t be negative.

So the option $(b)$ is correct

Domain of function $\sqrt {\sin 2x} $ is $[n\pi ,\,n\pi + \pi /2]$.
