7. Rank of the diagonal matrix
1
2
3
4
8. Matrix, A =
orthogonal
non-singular
have A-1 exists
both (b) & (c)
9. The matrix B = AT, where A is any matrix is
skew symmetric
symmetric about the secondary diagonal
always symmetric
another general matrix
10. Eigen values of a real symmetric matrix are always
