Compute the cofactor of the element a21 in the matrix [1 2; 3 4].a.2b.1c.-1d.-2
Question
Solution 1
The cofactor of an element in a matrix is calculated by removing the row and column of that element, finding the determinant of the resulting 1x1 matrix, and then multiplying by (-1)^(i+j), where i and j are the row and column numbers of the element.
