数形结合是数学中的一种最基本,最常用的方法,也是高考数学中的一个重要的、必考的解题思想方法。在中学数学课程中,有很多内容本身就是集“数”、“形”于一体的良好载体。如集合的交、并、补运算,向量,函数,解析几何等等。下面以函数为例,体会数形结合方法的简便和巧妙之处。函数是体现数形结合方法的良好载体,数形结合方法
Number-shape combination is one of the most basic mathematics, the most commonly used method, but also mathematics in college entrance examination an important, necessary test solution thinking method. In middle school mathematics curriculum, a lot of content itself is a set of “number ”, “form ” in one good carrier. Such as collection of pay, and, make up operations, vectors, functions, analytic geometry and so on. The following function, for example, experience the combination of digital form simple and clever. The function is a good carrier that embodies the method of number-shape combination, and the number-shape combination method
