摘要
利用图解法,根据二阶和三阶行列式的对角线法则,通过总结规律,推导出四阶行列式的对角线法则,提供一种四阶行列式展开的图解方法,使普通四阶行列式的计算更具有可操作性.
Based on the diagonal rule of two order determinant and three order determinant, the expansion law is summarized. Then the expansion method of four order determinant is provided by use of the graphical method. The computation of common four order determinant will be more practical.
