Solved Find The Determinant Of The Given Matrix A Using Chegg For cofactor expansions, the starting point is the case of 1 × 1 matrices. the definition of determinant directly implies that. det (a) = a. to describe cofactor expansions, we need to introduce some notation. let a be an n × n matrix. th column. is defined in terms of the minor by cij = ( − 1)i j det (aij). For example, let a be the following 3×3 square matrix: the minor of 1 is the determinant of the matrix that we obtain by eliminating the row and the column where the 1 is. that is, removing the first row and the second column: on the other hand, the formula to find a cofactor of a matrix is as follows: the i, j cofactor of the matrix is. Cij equals (−1)i j times the determinant of the. n − 1 by n − 1 square matrix obtained by removing row i and column j. (cij is positive if i j is even and negative if i j is odd.) for n × n matrices, the cofactor formula is: det a = a11c11 a12c12 · · · a1nc1n. applying this to a 2 × 2 matrix gives us: a b = ad b(−c). Step 1. find the determinant of the matrix, expand by cofactors using the row or column that appears to make the computations easiest. ⎣⎡ 2 −2 6 0 9 0 1 4 −4 3 2 −5 1 0 7 −6 ⎦⎤ step 1 recall that the determinant of a square matrix is the sum of the entries in any row or column multiplied by their respective cofactors.

This is the first stage of the calculation, and we have succeeded in expressing the determinant of the \(4 \times 4\) matrix \(a\) in terms of the determinant of a \(3 \times 3\) matrix. the next stage involves this \(3 \times 3\) matrix. again, we can use any row or column for the cofactor expansion. the third column is preferred (with two. The matrix which you have posted is also known as the ‘cofactor matrix’. the transpose of this cofactor matrix is more commonly used, and is known as the adjoint or adjugate of the matrix, denoted by adj(a) adj ( a). it is a well known (and easily proven) property for an square matrix of order n n that. a adj(a) =|a|in, a adj ( a) = | a | i n,.
