Show that the matrix `A = [(1,2,1),(3,2,3),(1,1,2)]` is non-singular and find `A^(-1)`.

Show that the matrix [{:(3,1,4),(2,0,-1),(5,2,1):}] is non-singular and reduce it to the identiy matrix by elementary row transformations.

The matrix A=[(2,lamda,-4),(-1,3,4),(1,-2,-3)] is a non-singular, if

For what value of x the matrix A = [(1,-2,3),(1,2,1),(x,2,-3)] is singular.

The matrix [(2,lambda,-4),(-1,3,4),(1,-2,-3)] is non singular , if :

The matrix [(2,lambda,-4),(-1,3,4),(1,-2,-3)] is non-singular if -

The matrix [(2,lambda,-4),(-1,3,4),(1,-2,-3)] is non singular , if :

Show that the matrix A = (1)/(3)[(1,2,2),(2,1,-2),(-2,2,-1)] is orthogonal, Hence, find A^(-1) .
