根据克莱姆法则以及行列式、混合积的几何意义,结合齐次线性方程组只有零解的几何解释,运用几何的方法得到克莱姆法则的几何意义.
According to Cramer's rule and geometric meaning of the determinant and mixed product of vectors,combined with homogeneous linear equations only geometric interpretation of zero solution,I use geometric methods to obtain geometric meaning of Cramer's rule.
