WebFor a 4 x 4 matrix, the checkerboard has the form and so on. Example 2: Compute the determinant of the following matrix: First, find the row or column with the most zeros. Here, it's the third row, which contains two zeros; the Laplace expansion by this row will contain only two nonzero terms. WebSep 16, 2024 · Theorems 3.2.1, 3.2.2 and 3.2.4 illustrate how row operations affect the determinant of a matrix. In this section, we look at two examples where row operations are used to find the determinant of a large matrix. Recall that when working with large matrices, Laplace Expansion is effective but timely, as there are many steps involved.

WebThese are the coefficients of the 3 by 3 determinants but with alternating signs, that is 1, -4, 2, -3. Each of these coefficients is multiplied by the 3 by 3 determinant obtained by removing the row and column of the 4 by 4 determinant that contains this coefficient. For example looking at the 2 in the first row of the 4 by 4 determinant, the ... WebSep 17, 2024 · Theorem 3.2. 1: Switching Rows. Let A be an n × n matrix and let B be a matrix which results from switching two rows of A. Then det ( B) = − det ( A).
