Sarrus rule extension for 4x4 and 5x5 determinants
In this work we propose a mechanism that shortens the manual calculation of the cofactors method for the case of the determinants of the 4 × 4 and 5 × 5 matrices by means of an extension of the wellknown Sarrus’ rule. Later we give an illustrative example of the method for each case and at the end we present conclusions. Mathematics Subject Classification: 15A15,15A23,15A99
期刊介绍:
The International Journal of Algebra and Computation publishes high quality original research papers in combinatorial, algorithmic and computational aspects of algebra (including combinatorial and geometric group theory and semigroup theory, algorithmic aspects of universal algebra, computational and algorithmic commutative algebra, probabilistic models related to algebraic structures, random algebraic structures), and gives a preference to papers in the areas of mathematics represented by the editorial board.
