Question

# For a given matrix A = which of the following statement holds good:

- A = A
^{–1} R
- A is symmetric, for θ = (2n +1), n I
- A is orthogonal matrix for θ R
- A is skew symmetric, for θ = n, n I

^{–1}R## The correct answer is: A is orthogonal matrix for θ R

### For θ = (2n +1)

A=which is not symmetric for θ = n

A = which is not skew symmetric

A^{2} = ≠ I so A ≠ A^{–1}
