All Cofactor Expansions of a 2x2 Matrix | Linear Algebra Exercises
We do two examples of finding all cofactor expansions of a 2x2 matrix. That is, we find the cofactor expansions along each row, and the cofactor expansions along each column. As we'll see, the cofactor expansions is the same no matter which row or column we choose, and this is the determinant of the matrix. #linearalgebra Cofactor Definition of ...
