" 4.For any square matrix A,show that AA' is symmetric."

For any square matrix A,prove that A+A' is symmetric.

State ‘True’ or ‘False’. For any square matrix A, A+A' is symmetric.

State'True'or'false':For any square matrix A, AA' is symmetric.

If A is any square matrix, show that 1/2(A + A') is symmetric and 1/2(A-A') is skew-symmetric.

State ‘True’ or ‘False’. For any square matrix A, A-A' is skew symmetric.

Solve the following:If A is a square matrix, show that A+A^T is symmetric

For any square matrix write whether AA^(T) is symmetric or skew-symmetric.

For any matrix a show that A+A^(T) is symmetric matrix

For any square matrix write whether A A^T is symmetric or skew-symmetric.

Which one of the following is wrong? 1.The elements on the main diagonal of a symmetric matrix are all zero 2. The elements on the main diagonal of a skew-symmetric matrix are all zero 3. For any square matrix A,(1)/(2)(A+A') is symmetric 4. For any square matrix A,(1)/(2)(A-A') is skew-symmetric
