A alternative "short cut" for calculating 3x3 determinants (Rule of Sarrus)Watch the next lesson: ...

Here we explain what the Rule of Sarrus is and how to find the determinant of a 3×3 matrix using the Rule of Sarrus. In addition, we will discuss whether the Rule of Sarrus can also be used to compute a 4×4 determinant or not. And, finally, you will see solved exercises of 3×3 determinants applying this method.

Here is one result suggested by Gerhard Paseman's comments. The False Sarrus Rule is correct on all matrices of rank 1 and 4×4 and 5×5 matrices of rank 2.

In linear algebra, the Rule of Sarrus is a mnemonic device for computing the determinant of a matrix named after the French mathematician Pierre Frédéric Sarrus. Consider a matrix then its determinant can be computed by the following scheme.

Theorem 1 (Sarrus' rule) . The determinant of a square matrix A of order 3 is given by the sum of the prductso of the elements in the main diagonals minus the sum of the prductso of the elements in the anti-diagonals. In formula detA = (a 11a 22a 33 +a 12a 23a 31 +a 13a 21a 32) | {z } sum of ductspro along main diagonals (|a 13a 22a 31 +a 11a {z23a 32 +a 12a 21a 33})

Notes on Sarrus' rule Carlo Maria Scandolo Like for square matrices of order 2, for square matrices of order 3 there is a mechanical rule to calculate the determinant that does not make use of the cofactor expansion, and sometimes this can be more convenient. This is called Sarrus' rule . Suppose we want to calculate the determinant of a

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 linear algebra, the Rule of Sarrus is a mnemonic device for computing the determinant of a 3 × 3 {\displaystyle 3\times 3} matrix named after the French mathematician Pierre Frédéric Sarrus .

The Rule of Sarrus Is used to calculate the result of 3 × 3 determinants. These are used to solve linear equations And know if they are compatible.

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 matrix!):

Sarrus Rule: write down three rows of the △ and rewrite the first two rows. The three diagonals sloping down to the right given the three positive terms ...

The Rule of Sarrus is essentially a quick way of memorizing this little technique. You write the two columns again, you say, ok, this product plus this product plus this product, minus this product minus this product minus that product. Let's actually do it with the 3 by 3 matrix to make it clear that the Rule of Sarrus can be useful.
