Solved Compute The Determinant Of The Matrix By Cofactor Chegg Question: compute the determinant of the matrix by cofactor expansion. 3 2 7) 2 5 2 a) 150 solve the problem. b) 20 c) 60 d) 20 21 4 4 8) determine if the columns of the matrix a = are linearly independent. 0 4 8 2 12 a) no b) yes 4 3 |, and b 9) let a1 | 5 2 = | 4 26 10 determine whether b can be written as a linear combination of a1 and a2. This last expression can be described as follows: to compute the determinant of a \(3 \times 3\) matrix \(a\), multiply each entry in row 1 by a sign times the determinant of the \(2 \times 2\) matrix obtained by deleting the row and column of that entry, and add the results. the signs alternate down row 1, starting with \( \). Step 1. choose the row or column with the most 0 elements. if there are no 0 elements choose any row or column compute the determinant of the matrix by cofactor expansion.

Let’s see and example of how to solve the determinant of a 3×3 matrix using cofactor expansion: first of all, we must choose a column or a row of the determinant. in this case, we choose to apply the cofactor expansion method to the first column, since it has a zero and therefore it will be easier to compute. so we have to multiply the.

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). A determinant is a property of a square matrix. the value of the determinant has many implications for the matrix. a determinant of 0 implies that the matrix is singular, and thus not invertible. a system of linear equations can be solved by creating a matrix out of the coefficients and taking the determinant; this method is called cramer's.
