Some more question about linear algebra: how do you know when to form a matrix
by inserting into the columns and when to form one by inserting into rows?

Can someone please explain how images, kernels, isomorphisms, and the dimension
theorem relate?

And what's diagonizability? I know the A-(lambda*I) thing, and then the
determinant of that is the "characteristic polynomial" of the matrix. But how
does that determine diagonizability?

Also, if det (A) = 0, then the matrix isn't invertible. This means NOTHING
times A can equal I, right?

I understand the use of A^(-1) in linear algebra. But what's the use of A
transpose?
