Question

Answer 1

Symmetric matrix

A square matrix A is said to be symmetric if

A(transpose) = A

Skew symmetric matrix

A square matrix A is said to be skew symmetric if A(transpose) = -A

Answer 2

Answer:

if the transpose of a matrix is equal to the negative of itself the matrix is said to be skew symmetric . this means that for a matrix to be skew symmetric ,A'=-A. also ,for the matrix ,a_(ji)= -a (ij) (for all the values of i and j) . the diagonal elements of a skew symmetric matrix are equal to zero
