A square matrix `B` is said to be an orthogonal matrix of order `n` if `BB^(T)=I_(n)` if `n^(th)` order square matrix `A` is orthogonal, then |adj(adjA)| is

If nth-order square matrix A is a orthogonal, then |"adj (adj A)"| is

If A is order 3 square matrix such that |A|=2 , then |"adj (adj (adj A))"| is

If a square matrix A is orthogonal as well as symmetric, then

Let A be an orthogonal non-singular matrix of order n, then |A-I_n| is equal to :

If A is square matrix order 3, then |(A - A')^2015| is

If a square matrix A is involutory, then A^(2n+1) is equal to:

If A is a square matrix of order 3 such that |A|=5 , then |Adj(4A)|=

If A is a square matrix of order 3 such that |A|=2 , then |(adjA^(-1))^(-1)| is

A square matrix A is said to be orthogonal if A^T A=I If A is a square matrix of order n and k is a scalar, then |kA|=K^n |A| Also |A^T|=|A| and for any two square matrix A d B of same order \AB|=|A||B| On the basis of above information answer the following question: IF A is a 3xx3 orthogonal matrix such that |A|=1, then |A-I|= (A) 1 (B) -1 (C) 0 (D) none of these

If M and N are orthogonal matrices of order 3, then which of the following is (are) orthogonal matrix?
