向量作为一种既有大小又有方向的量,兼具数与形的特征,是联系数与形的重要工具,在解题中具有独特的功能,其应用极其广泛.那么,在解题中如何想到利用向量呢?本文介绍几种联想途径,并拟例说明,供读者参考.一、相似联想所谓相似联想,就是对两个对象的外形进行观察、分析,由某一事物或现象想到与之相似的其他事物或现象,进而产生某种新设想,其主要特征体现在对研究对象外形的观察与分析上.在解决某些数学问题时,可以通过观察分析题目的结
As a kind of both the size and the direction of the amount of both the number and shape of the characteristics of the number and shape of the link is an important tool in the problem has a unique function, its extremely wide range of applications. Then, in the problem-solving How to think of the use of vectors? This article describes several ways of associative and intended to illustrate, for readers reference.. Similar to the so-called similar associations Lenovo is the appearance of the two objects observed and analyzed by a thing or phenomenon Similar to other things or phenomena, and then produce some new ideas, the main characteristics of the object in the observation and analysis of the shape of the object in the settlement of some mathematical problems, you can analyze the problem by analyzing the end
