(b) answer the foll. Questions: (i) express the matrix A=[[3,2,3],[4,5,3],[2,4,5]] as the sum of a symmetric matrix and a skew -symmetric matrix.

Express the matrix B=[(2,-2,-4),(-1,3,4),(1,-2,-3)] as the sum of a symmetric and a skew symmetric matrix.

Express [[4,3,7],[6,5,-8],[1,2,6]] as the sum of a symmetric matrix and a skew symmetric matrix .

If matrix A=[(0,1,-1),(4,-3,4),(3,-3,4)]=B+C , where B is symmetric matrix and C is skew-symmetric matrix, then find matrices B and C.

If the matrix A is both symmetric and skew symmetric then

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