Show that the matrix B'AB is symmetric or skew symmetric according as A is symmetric or skew symmetric.

If the matrix A is both symmetric and skew symmetric, then

If a matrix A is both symmetric and skew symmetric, then

Define a skew-symmetric matrix.

If A is symmetric as well as skew-symmetric matrix, then A is

Mention the most symmetrical and most unsymmetrical crystal system

For any square matrix A with real numbers, prove that A + A' is a symmetric and A - A' is a skew symmetric.

If the matrix [(2,3),(5,-1)]=A +B , where A is symmetric and B is skew symmetric, then B=

Define a symmetric relation.
