I haven't written a proof in 8 years. Linear Algebra proofs are going to be the death of me. I honestly don't know where to begin. I read a sort of primer on proof writing, but I could use a human walk through or some help.(adsbygoogle = window.adsbygoogle || []).push({});

So far, I have:

there exists a B such that AB = BA = I.

then sometime later:

(A^T)B = B(A^T) = I

Beyond this I have no idea. I'm going to visit my prof tomorrow and see what he has to say. The trouble is, is that his english is fair to poor. A heads up or some honest help would be friendly,

Thanks.
