  1. Jun 16, 2005 #1
    This one, prove it please, I have 5 problems in linear algebra class as an assignment which I have to hand in next week's Monday and I don't know how to solve this problem, the last one;
    [tex]A^-=\frac{(A_j_k)^T}{det(A)}=\frac{(A_j_k)}{det(A)}[/tex]

    Thank you

    I don't know about everyone else, but your notation is not clear to me. Is this a matrix equation? Are you talking about an element of a matrix? Did you lose a 1 on the left hand side? Did you mix up the indices somewhere?
