A matrix which is both symmetric and skew-symmetric is a

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 A is skew-symmetric matrix then A^(2) is a symmetric matrix.

It A is a symmetric matrix, write whether A^T is symmetric or skew - symmetric matrix.

If A is a non-singular symmetric matrix, write whether A^(-1) is symmetric or skew-symmetric.

If A is skew-symmetric matrix, then trace of A is

If A is a symmetric matrix and n in N , write whether A^n is symmetric or skew-symmetric or neither of these two.
