数学是研究数量关系与空间形式与数量关系的学科,“数”与“形”以及它们的互相联系与转化是数学的永恒主题.从初中开始数学就以数和形两个基本概念为主干,分化为代数和几何两个分支.然而,对于数和形的研究尤其是在具体的应用中从来就不是绝对分开的.可以用代数方法解决几何问题,也可以运用几何方法探讨代数问题.正如著名数学家华罗庚所说“数缺形时少直观,形少数时难入微”.“数”与“形”的这种本质存在的必然联系促使
Mathematics is to study the relationship between quantity and space forms and the number of disciplines, “Number ” and “Shape ” and their interrelation and transformation is the eternal theme of mathematics .Since junior high school mathematics on the number and form two basic Concept as the backbone, the division into the two branches of algebra and geometry.However, the number and shape of the study, especially in specific applications has never been absolutely separate.Algebraic methods can be used to solve the geometric problems, you can also use the geometric method to explore the algebra As the well-known mathematician Hua Luogeng said, “the lack of intuition is less intuitive when in its infancy, and the inevitable connection between the” number “and the” essence "is prompted by
