Symmetric and skew symmetric matrices | Matrices | Grade 12 | Math | Khan Academy

In this video, we talk about symmetric and skew symmetric matrices. We first look at examples of each and then understand the constraints on the elements. We then verify 2 results that work for sum and difference of a matrix and its transpose. We finally derive these results using properties of transpose of a matrix.
