Answer 2

\(A^T\) mean A transpose, when you have a matrix A with n row and m column, its transpose is a matrix with row becomes column and column becomes row, for example
\[A = \left[\begin{matrix}1&2&3&4\\0&3&6&5\end{matrix}\right]\]
\[A^T= \left[\begin{matrix}1&0\\2&3\\3&6\\4&5\end{matrix}\right]\]
you can see row1 of A becomes column1 of \(A^T\)
That's what "T above" means
