For an nxn matrix a, explain how to find each value. (a) the minor mij of the entry ajj take the determinant of the nxn matrix that is left after deleting the ith row and ſth column. take the determinant of the (n - 1) (n - 1) matrix that is left after deleting the jth row and jth column. take the determinant of the (n - 1) (n - 1) matrix that is left after deleting the ith row and jth column. take the determinant of the n xn matrix. take the determinant of the (n − 1) (n-1) matrix that is left after deleting the ith row and ith column. (b) the cofactor cij of the entry aj • cij = mij if i + j is negative, then cij = -m; j. if i + j is positive, then cij = mijo cij = -mij if i + j is odd, then cij = mij. if i + j is even, then cij = -mije if i +j is odd, then cij = -mj. if i + j is even, then cj = m; j. (c) the determinant of a. o a| = 211c12 + 212c11 + + 21nin o|a| = 211c11 + 212-12 + + aincin a| = 211c11 - 312c12 + - 21cin o|a| = 211c11 - 212c12 - - 21cin o|a| = 211c11 +222c22 + + ann con
