(Some) Matrices and Determinants
... The second representation of the determinant matrix is just to show where the math comes from. Procedure: 1. Repeat the first two columns (after red dashed line) 2. Multiply diagonals. From left to right is a positive contribution, from right to left is a negative contribution (note that signs m ...
