平面向量是高中数学必修部分的重要内容,也是高考必考内容之一.该模块知识在数学、物理等学科中有着广泛的应用.它具有几何形式和代数形式的双重身份,是数形结合的重要载体.因此,平面向量成为中学数学知识的一个交汇点.平面向量涉及的数学方法较多,本文介绍几种常见的方法:基底法,坐标法,参数法,几何法,平方法,供大家参考.1.基底法:选择不共线的两个向量作为一组基底,用它们表示平面内其它的向量,从而进行运
Plane vector is a compulsory part of high school mathematics is an important part of the content is one of the college entrance examination will be the module knowledge in mathematics, physics and other disciplines has a wide range of applications. It has a geometric form and algebra form of dual identity is a combination of number Therefore, plane vector has become a meeting point of middle school mathematics knowledge.Plane vectors involve more mathematical methods, this article introduces several common methods: base method, coordinate method, parametric method, geometric method, flat method for everyone Reference .1. Base method: Choose two non-collinear vectors as a group of bases, use them to represent other vectors in the plane,
