【摘要】 在平面与空间解析几何中,利用线性方程组理论确定两条直线之间的位置关系,并且利用齐次线性方程组的一个结论求出二元方程组的解,此外它还可以判别一元多次方程的重根,从而将大学所学的高等数学知识应用到初等数学中,为在初等数学中应用高等数学知识打下一个铺垫。更多还原

【Abstract】 In this paper,we give a number of examples to show that the theory of group of linear equations can be applied to teaching primary mathematics.We can confirm the ubiety about two beelines in the plane and space analytic geometry,obtain the solution of two variable equations according to a conclusion of homogeneous linear systems,and judge multioots of equation of higher degree with one unknown,and apply the knowledge of advanced mathematics studied in university into primary mathematics and make a preparation for applying the knowledge of advanced mathematics into primary mathematics.更多还原
