学数学的目的一方面是为了提高自己的想象能力,另一方面就是为了应用。马克思曾说过:“一门科学只有成功地运用数学时,才算达到了完善的地步”。可以认为数学在各门科学中被应用的水平,也就标志着这门科学发展的水平。为此,数学的应用已越来越受到人们的重视。在新教材里,我们可以发现,几乎每一章节的开头都是通过实际问题引入数学知识的。本文通过建立与实际生活问题对应的数学模型,化实际问题为数学问题,从而达到用中学数学知识和思想方法求解出实际问题的目的。
The purpose of learning mathematics is to improve one’s imagination ability on the one hand, and on the other hand to apply. Marx once said: “A science can only reach its perfect point if it is successfully applied to mathematics.” It can be considered that the level of application of mathematics in various sciences also marks the level of scientific development. Therefore, the application of mathematics has drawn more and more attention. In the new textbook we can see that almost every chapter begins with the introduction of mathematical knowledge through practical questions. In this paper, by establishing a mathematical model corresponding to the actual life problem, the actual problem is a mathematical problem, so as to achieve the purpose of solving practical problems by using the mathematical knowledge and thinking method of middle school.
