Solve the following.
For what value of k the matrix [0 k; -6 0] is a skew symmetric matrix?
For what value of $k$ the matrix $\begin{bmatrix} 0 & k \\ -6 & 0 \end{bmatrix}$ is a skew symmetric matrix?
Answer
Answer
For a skew symmetric matrix $a_{ij} = -a_{ji}$, so $a_{12} = -a_{21}$.
$k = -(-6) = 6$
Hence $k = 6$.
Final answer: 6
