平面向量兼备代数与几何双重形式,数形一体,是解决数学问题的重要工具.为了体现平面向量的工具性,向量与诸多数学内容的广泛联系,错综交汇的特点,形成了高考命题的关注点.针对这种情况,重视平面向量自身知识点复习的同时,突出与其它数学知识交汇处的特征的复习,复习时应注意以下几个方面:一、平面向量的运算由于向量有几何法和坐标法两种表示,它的运算和向量问题的解决也就有两种途径,即基于几何表示的几何法和基于坐标表
Plane vector is an important tool to solve mathematical problems, which combines both the form of algebra and geometry, and the form of number and form.In order to embody the features of plane vector, the extensive connection between vector and many mathematical contents and the features of intricate intersection, the formation of the focus of college entrance examination proposition In view of this situation, pay attention to the knowledge of the plane vector review points at the same time, highlighting the characteristics of the intersection with other mathematical knowledge review, review should pay attention to the following aspects: First, the calculation of vector plane Because the vector has geometry and coordinates The two methods, said that its operation and vector problems also have two ways to solve, that is based on geometric representation of the geometric method and based on the coordinate table
