借助数与形的相互转化来研究和解决问题的数学思想叫做“数形结合思想”.著名数学家华罗庚曾有过精辟的论述:“数缺形时少直观,形缺数时难入微.”数学中有许许多多的问题,通过数形结合来分析,可以快速直观地找到解决问题的思路,从而非常简单地得到答案.数学高考的宗旨之一是考查考生对基础知识、基本技能、 The mathematical idea of ​​studying and solving problems by means of the mutual transformation of numbers and forms is called “combination of ideas and figures”. The famous mathematician Hua Luogeng had an incisive argument: “The lack of intuition is less intuitive, ”There are so many problems in mathematics, through the combination of number-shape analysis, you can quickly and intuitively find the way to solve the problem, which is very simple to get the answer.Mathematics entrance exam, one of the purposes is to examine the candidates for basic knowledge, basic skills,
