The Sarrus Rule A Short Method For Computing 3x3 Matrix Determinant [UTME MATH] Education
Rule of Sarrus: The determinant of the three columns on the left is the sum of the products along the down-right diagonals minus the sum of the products along the up-right diagonals. In matrix theory, the Rule of Sarrus is a mnemonic device for computing the determinant of a matrix named after the French mathematician Pierre Frédéric Sarrus. [1]

12 years ago Probably should mention that the Rule of Sarus only applies to 3x3. You cannot use it for 4x4 or higher. • 1 comment ( 54 votes) Upvote Flag Norberto Galdini 10 years ago Actually, there seems to be a method to extend this to 4x4 and even higher matrices. I found this one article, where it is described:
How to calculate determinant of 3x3 matrix (Rule of Sarrus) easy way math YouTube
rule of Sarrus. with three rows, it is comfortable to use the rule of Sarrus (invented 1833 by the French mathematician P. F. Sarrus). The rule comprises that first one writes the two first columns of the determinant on the of the determinant (seeing thus a 3×5 3 × 5 matrix!): Here one sums the products on all lines parallel to the main.
SARRUS METHODE RAPIDE POUR CALCULER DES DETERMINANTS 3x3. Algèbre. YouTube
To find the determinant of a 3×3 matrix using the Rule of Sarrus, duplicate the first two columns of the matrix to the right of its third column. Then, add the products of the main diagonals going from top to bottom and subtract the products of the main diagonals going from bottom to top.
SARRUS RULE FOR DETERMINANT SARRUS RULE FOR 3×3 MATRIX DETERMINANT HINDI YouTube
This is our definition of the determinant of a 3 by 3 matrix. And the motivation is, because when you take the determinant of a 3 by 3 it turns out-- I haven't shown it to you yet-- that the property is the same. That if the determinant of this is 0, you will not be able to find an inverse.

Can Sarrus' method of finding the determinant be used for finding the determinant of matrices greater than $3\times3$, as I am unable to find any example of a matrix greater than $3\times3$ whose determinant is found by Sarrus' method?. I have tried many questions and Sarrus' method only works for $2\times2$ and $3\times3$ matrices. I have not read about Sarrus' method in any book but only.

For a 3x3 matrix the determinat can be calculated with the Sarrus rule. The Sarrus rule uses the diagonals for the calculation. The calculator shows the calculation steps. For illustration the elements of the main diagonals are colored in green and the elements of the secondary diagonals are colored in blue.

I know that the determinant of this matrix: $ \begin{bmatrix} 2-\lambda & -1 & 1\\1& 5-\lambda & -2 \\ 0 & 1 & 2-\lambda \end{bmatrix} $ is $(3-\lambda)^3$ by simply computing the determinant (using Sarrus method), but I want to know if I can compute this determinant faster, by doing some operations with the rows and columns.
