Determine for which value (s) of k will the matrix below be non-singular.
(9.1) A = 2−k −3
2 k+1
(9.2) A = 2 2 1
3 1 3
1 3 k
A matrix is said to be singular when the determinant of that matrix is 0
(9.1)
solving by this we did not get any real value if k , So we can say that for all values of k matrix will be non-singular matrix.
(9.2)
So , we can say except k= -1, for all values of k the matrix will be non-singular matrix.
