3.2 Cofactor Expansion. DEF (→ p. 152) Let A = [aij] be an n × n matrix. • Mij denotes the (n − 1)×(n − 1) matrix of A obtained by deleting its i-th row ...
Cofactor expansions are most useful when computing the determinant of a matrix that has a row or column with several zero entries. Indeed, if the ( i , j ) ...
This method to calculate the determinant of a 3×3 matrix is called the cofactor expansion method. Remember that to find the determinant of a 2×2 matrix, you have to multiply the elements on the main diagonal and subtract the product of the elements on the secondary diagonal. Example of the determinant of a 3×3 matrix
