We go over how to find the minors of a matrix and how to find the cofactors of a matrix. The minor of an entry aij is the determinant of the submatrix when row i and column j are deleted. The cofactor of an entry aij is the minor Mij multiplied by (1)^(i+j). We go over several examples of finding minors and cofactors of 2x2 matrices, we also find the minors and cofactors of a 3x3 matrix using the cofactor expansion of the determinant. #linearalgebra
