A) \[\theta =n\pi \]
B) \[\theta =2n\pi \pm \frac{\pi }{2}\]
C) \[\theta =n\pi \pm {{(-1)}^{n}}\frac{\pi }{4}\]
D) \[\theta =2n\pi \pm \frac{\pi }{4}\]
Correct Answer: B
Solution :
After solving the determinant \[2\cos \theta =0\] Þ \[\theta =2n\pi \pm \frac{\pi }{2}\].You need to login to perform this action.
