A) 4
B) 3
C) 2
D) 1
Correct Answer: D
Solution :
\[A+{{A}^{T}}=O\Rightarrow \,\left[ \begin{matrix} 2\,\sin \,\theta \\ 0 \\ \end{matrix}\,\,\begin{matrix} 0 \\ -2\,\sin \,\theta \\ \end{matrix} \right]=O\] \[\Rightarrow \,\sin \,\theta \,=0\,\Rightarrow \,\theta =\,n\pi ,\,\,n\,\in \,I\] \[\therefore \,\,\theta \,=\pi \,\in \,(0,6)\]You need to login to perform this action.
