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

Fill in the blanks: If a square matrix is both symmetric and skew symmetric then it is a ………. Matrix.

A square matrix A is called orthogonal if.

If a matrix A is symmetric as well as anti-symmetric, then which one of the following is correct ?

If the matrix A is both symmetric and skew symmetric, then (A) A is a diagonal matrix (B) A is a zero matrix (C) A is a square matrix (D) None of these

If the matrix A is both symmetric and skew symmetric, then A is a diagonal matrix A is a Zero matrix Ai is a Square matrix None of these

If the matrix A is both symmetric and skew symmetric, then: A)A is a diagonal matrix B)A is a zero matrix. C) A is a square matrix D)None of these.

If square matrix a is orthogonal, then prove that its inverse is also orthogonal.

If square matrix a is orthogonal, then prove that its inverse is also orthogonal.
