Matrices

Consider the set A of all matrices of order 3 xx 3 with entries 0 or 1 only. Let B be the subset of A consisting of all matrices whose determinant is 1. Let C be the subset of A consisting of all matrices whose determinant is -1. Then which one of the following is correct ?

Osmotic potential and Matric potential

Find adjoint of the matrice in [(1, 2),( 3, 4)]

If matric A is skew-symmetric matric of odd order, then show that tr. A = det. A.

if a matric has 10 elements , write all possible order of the matrix.
