向量具有代数与几何形式的双重身份,故它是联系多项知识的媒介,成为中学数学知识的一个交汇点.数学高考重视能力立意,在知识网络的交汇点上设计试题,因此,解析几何与平 The vector has a dual identity of algebra and geometry, so it is a medium that connects multiple knowledge and becomes a meeting point for middle school mathematics knowledge. The mathematics college entrance examination attaches great importance to competence and design questions at the intersection of knowledge networks. Therefore, analytical geometry and level
