Is determinant of symmetric matrix is zero

WebA determinant is calculated for matrix “A” with where the subscripts indicate the row and column, respectively. A skew symetric matrix is a matrix in which its transpose is its own opposite. In other words, the diagonals must be negatives of themselves (so all 0), and each element must be opposite across the diagonal, or must equal .
