For what value of x is the matrix A=[(0,...

For what value of `x` is the matrix `A=[(0,1,-2),(1,0,3),(x,3,0)]` a skew-symmetric matrix?

Text Solution

Verified by Experts

Given that,
`A=[(0,1,-2),(1,0,3),(x,3,0)]`
`A` is skew symmetric matrix
`A^T=[(0,1,x),(1,0,3),(-2,3,0)]`
`A^T=-A`
`[(0,1,x),(1,0,3),(-2,3,0)]=-[(0,1,-2),(1,0,3),(x,3,0)]`
Equating both sides,
`x=-(-2)=2`
