    Why Do the Determinants of a Matrix and Its Transpose Equal?

    Can Laplace's Expansion be used either across a row or down a column? I thought by definition it needed to be used across a row?

    Why Do the Determinants of a Matrix and Its Transpose Equal?

    How do you go about proving that the determinant of a nxn matrix A is equal to the determinant of the transpose of said matrix A using Laplace's expansion? How can you use Det(AB) =Det A x det B to help with this?

    Proving transpose(AB)=transpose(B)*tranpose(A) Help Needed

    How do you go about proving that the determinant of a nxn matrix A is equal to the determinant of the transpose of said matrix A using Laplace's expansion? How can you use Det(AB) =Det A x det B to help with this?
