做任何事情都要讲究方法策略,解答数学问题也不例外,以下对典型的平面向量问题的解题策略予以透视.1.策略1———“互译”策略平面向量问题,往往既有“数”的构成要件,也有“形”的背景,此时,要注意恰当选取翻译方式,实现快捷解题.例1已知平面上三点A,B,C满足AB=3,BC=4,CA=5,则 When doing anything, we must pay attention to method strategies and solve mathematics problems. The following is a perspective of the problem solving strategies for typical plane-vector problems. 1. Strategy 1—“Inter-translation” strategy Plane vector problems, often with “ The “number” component also has a background of “shape”. At this time, we must pay attention to the proper choice of translation methods to achieve quick solution. Example 1 Known three points A, B, and C on the plane satisfy AB=3, BC=4, CA=5, then
