数学是研究现实世界的空间形式和数量关系的科学,数和形是数学中两大研究对象,也是整个数学发展进程中的两大柱石。在平面引入笛卡儿坐标系后,就出现了以数论形、精确深刻的解析法和以形论数、直观简洁的几何法。因此,数形结合法是数学中最重要的数学思想方法,在高考中颇受重视,也具有广泛的应用。下面笔者谈谈数形结合法几个方面的应用。 Mathematics is the science that studies the relationship between the spatial form and the quantity in the real world. The number and form are the two major research subjects in mathematics and the two pillars in the development of mathematics. After the Cartesian coordinate system was introduced into the plane, there appeared the geometric method of number theory, precise and profound analysis, and the number of theory, which was intuitive and concise. Therefore, the number-shape combination method is the most important maths mathematical method in mathematics, attaches great importance to the college entrance examination, but also has a wide range of applications. The following author talk about the combination of several forms of several applications.
