Pierre Frédéric Sarrus was a French mathematician known for his contributions to differential equations and mathematical physics. He is best remembered for the Sarrus rule, a technique for calculating the determinant of a 3x3 matrix. The Sarrus rule offers a simple way to find the determinant using a visual method that involves the diagonals of the matrix.
