In this video I will tell you 2 tricks on how to construct examples of matrices which are symmetric and skew symmetric. The two tricks are: 1) by refeclting along diagonal line. 2) Add the given matrix with its transpose. We will see some examples to understand these tricks. At the end we will see the proof on why diagonal entries of skew symmetric matrix are zero.
