众所周知,平面向量具有“数”和“形”的双重身份.那么,在具体解题时,如何巧妙利用这个双重身份呢?本文结合2015年高考试题加以归类解析,以帮助读者提高解题技能.策略一:按“图”处理求解有关平面向量问题时,若能灵活利用平面向量加、减法法则的几何意义加以分析,则往往有利于问题的顺利获解.这种解题思路,我们不妨称之为按“图”处理.例1.(2015北京卷·理13)在△ABC中,点M,N满足AMMM=
As we all know, the plane vector has dual identities of “number” and “shape.” So, how to use this dual identity wisely when solving specific problems? In this paper, we classify the 2015 college entrance examination questions to help readers Improve the problem-solving skills.Policy one: Press “Figure ” to solve the problem of plane vector, if we can flexibly use the plane vector addition and subtraction method, the geometric meaning to be analyzed, it is often conducive to the smooth solution of the problem. Problem 1, we may wish to call the “Figure” treatment. Example 1. (2015 Beijing Volume · Li 13) △ ABC, the point M, N meet AMMM =
