Class 12 Maths · Matrices · Conceptual Answer #83
Write the 2×2 real matrix that is both symmetric and skew-symmetric.
✅ Step-by-Step Solution
Final Answer: \(\begin{bmatrix}0 & 0\\0 & 0\end{bmatrix}\)
- The conditions Aᵀ=A and Aᵀ=−A give A=−A, so every entry is zero.
- \(\begin{bmatrix}0 & 0\\0 & 0\end{bmatrix}\)
