| 摘 要： | 给出了二、三阶行列式恒等式．利用行列式的定义和数学归纳法两种方法给出证明．在一定条件应用恒等式去计算一些行列式和解线性方程组．一方面，从新的角度探讨了行列式自身的性质；另一方面，为快速计算带有字母的行列式（符号运算）提供了新的方法．其结果不能够包含在已有的经典方法中，补充了已有的结果．

| Abstract: | The second and third-order determinant identities is given in this paper,which is proved by the definition and mathematical induction method.The determinant identities can be applied to calculate identities determinant some reconciliation of linear equations in certain conditions.This paper discusses the nature of determinant from a new perspective,and provides a new approach to rapidly calculate of the determinant with the letter(symbol operator).The result unable to be included in the classic method,so it... |
