数形结合思想包含“以形助数”和“以数助形”这两个互相联系的侧面,它是把问题的数量关系和空间形式结合起来考查的一种思想.这种思想借助于数的精确性和形的直观性研究问题,常常使得复杂问题简单化,抽象问题具体化,运用这种思想解题常可以独辟蹊径,出奇制胜.本文仅探讨数形结合思想在函数与不等式综合问题中的运用. The idea of ​​number and shape combination includes the two interrelated aspects of “helping number by form” and “helping by number”. It is an idea that combines the quantitative relationship and spatial form of the problem. This idea uses the number The accuracy and shape of the intuitive study of the problem, often making the complexity of the simplification of the specific problems of the abstract, the use of this ideology can often be unique ways to solve problems. This article only discusses the combination of number and shape in the function and inequalities synthesis problems use.
