数形结合的思想在我们高中数学是非常重要的思想之一,简单来说就是数与形的有机的结合来解决问题,达到数与形的完美的结合,以数制型,以形得数。在高考试题中有相当一部分题目都用到该思想,它常用来研究方程的根,讨论函数的值域(最值)及求变量的取值范围等题目,对这类内容的选择题填空题,数形结合特别有效,故应引起我们的重视。我现在将它作为一条复习的轴线,看一下它与各章的知识点的联系,做一小结,现试举几例它在我们的各个章节试题,以便大家进一步的完善总结,以达到熟练的运用该思想起到抛砖引玉的效果。
Mathematical combination of ideas in our high school mathematics is one of the very important ideas, in simple terms is the combination of number and shape to solve the problem, to achieve the perfect combination of number and shape, with the number system, to form the number . There are quite a few topics in the entrance examination questions are used in this idea, it is often used to study the root of the equation, discuss the function of the range (value) and variable range of values and other topics, the choice of such content blank , Shape combination is particularly effective, it should arouse our attention. Now I will use it as a review of the axis, take a look at the knowledge of each chapter with the link, to make a brief summary, we give you a few examples of it in our chapters questions, so that we can further improve the summary in order to achieve proficiency Use this idea to start the effect.
