向量本身是一个几何概念,具有代数形式和几何形式两种表示方法,易于数形结合,而且向量问题在进行数形结合时具有新形式、新特点,因此可称为高中数学的一个交汇点。它一般通过概念的移植、转化,将坐标与向量结合起来,从而使一些难题在思路上获得新的突破。一、向量基本知识的运用以平面向量内部知识的小综合性试题在高考试卷中屡见不鲜,这类问题主要是突出向量的加减运算、模、夹角等问题,题 The vector itself is a geometric concept with both algebraic and geometric forms of representation, easy to form a combination of numbers, and vector problems in the form of a combination of new forms and new features, it can be called a high school mathematics intersection. It is generally through the concept of transplantation, transformation, the coordinates and vectors together, so that some of the challenges in the idea of ​​a new breakthrough. First, the use of vector basic knowledge of planar vectors Small comprehensive test papers in the college entrance examination papers are common, these problems mainly highlight the addition and subtraction vector, mode, angle and other issues, questions
