A) \[x=n\pi \pm \frac{\pi }{2}\]
B) \[x=n\pi \pm \frac{\pi }{4}\]
C) \[x=n\pi \pm \frac{3\pi }{2}\]
D) None of these
Correct Answer: B
Solution :
\[4+2{{\sin }^{2}}x=5\] \[\Rightarrow \] \[{{\sin }^{2}}x=\frac{1}{2}={{\sin }^{2}}\frac{\pi }{4}\Rightarrow x=n\pi \pm \frac{\pi }{4}\].You need to login to perform this action.
