摘要
通过引入体积坐标证明了行列式和多面体体积的关系,使得每一个行列式都有了它的几何解释,有助于形象地理解行列式的概念,并利用行列式的几何意义计算空间多面体的体积.
By introducing volume coordinates,the relationship between determinant and volume of polyhedron is established.Each determinant has its geometric significance,which is helpful to understand the concept of determinant vividly,and the volume of spatial polyhedron can be calculated by using determinant.
