- Det(A) = det(A^T) determinant of transpose equals determinant of the original matrix
This is the question. The following is the solutions I found:
I understand that the first line was derived by setting one vertex on origin and taking the transpose of the matrix. However, I cannot understand where the extra row and column came from in the second line. Can anyone explain how the formula is derived?
Thank you!
