WebJul 8, 2024 · The determinant can be calculated by using the proper method for this but on the other hand, if the resultant matrix is expanded for calculation, the result will be a1 3 + a2 3 + a3 3 – 3*a1*a2*a3. Hence, instead of calculating determinants by proper expansion use the above-generated formula. Therefore, the Determinant of the above Matrix ... WebLet's actually do it with the 3 by 3 matrix to make it clear that the Rule of Sarrus can be useful. So let's say we have the matrix, we want the determinant of the matrix, 1, 2, 4, 2, minus 1, 3, and then we have 4, 0, minus 1. We want to find that determinant. So by the Rule of Sarrus, we can rewrite these first two columns.
