Class 12 Maths · Matrices · Conceptual Answer #49
If \(\begin{bmatrix}0 & a & 3\\2 & b & -1\\c & 1 & 0\end{bmatrix}\) is skew-symmetric, find a,b,c.
✅ Step-by-Step Solution
Final Answer: a=−2,b=0,c=−3
- Skew-symmetry forces a=−2, c=−3 and the diagonal relation b=−b, hence b=0.
- a=−2,b=0,c=−3
📋 CBSE Stepwise Marking Scheme
- [0.5 marks] Skew-symmetry forces a=−2, c=−3 and the diagonal relation b=−b, hence b=0.
- [0.5 marks] a=−2,b=0,c=−3
