MCQ
यदि $A =\left[\begin{array}{cc}\sin ^2 \theta & \sec ^2 \theta \\ \operatorname{cosec}^2 \theta & \frac{1}{2}\end{array}\right]$ तथा $B=\left[\begin{array}{cc}\cos ^2 \theta & -\tan ^2 \theta \\ -\cot ^2 \theta & \frac{1}{2}\end{array}\right]$ हो, तो A + B का मान होगा-
- A$\left[\begin{array}{cc}1 & -1 \\ 1 & 1\end{array}\right]$
- B$\left[\begin{array}{ll}1 & 0 \\ 1 & 1\end{array}\right]$
- C$\left[\begin{array}{ll}1 & 0 \\ 0 & 1\end{array}\right]$
- ✓$\left[\begin{array}{ll}1 & 1 \\ 1 & 1\end{array}\right]$
