A matrix is symmetric if it is equal to its transpose. Give an example of: 1. A non-zero 2 x 2 symmetric matrix. 2. A non-zero 3 x 3 symmetric matrix. A matrix is skew-symmetric or antisymmetric if it is equal to the negative of its transpose. Give an example of: 1. A non-zero 2 x 2 skew-symmetric matrix. 2. A non-zero 3 x 3 skew-symmetric matrix. What can be said about a matrix that is both symmetric and skew-symmetric?
