Abstract

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

Sarrus规则扩展4x4和5x5行列式

在这项工作中，我们提出了一种机制，通过扩展著名的Sarrus规则，缩短了4 × 4和5 × 5矩阵的行列式的辅助因子方法的人工计算。随后，我们给出了每个案例的示例，并在最后给出了结论。数学学科分类:15A15、15A23、15A99
