数学高考命题注重知识的整体性和综合性 ,重视知识的交互渗透 ,由于向量具有代数与几何形式的双重身份 ,使它成为中学数学知识的一个交汇点 ,成为联系多项知识的媒介 .因此 ,解析几何与向量的交汇是新课程高考命题的必然趋势 .以下举几例说明 ,希望能够引起重视 .例 1　 ( 2 0 The mathematics college entrance examination proposition focuses on the integrity and comprehensiveness of knowledge, and emphasizes the interactive penetration of knowledge. Because vectors have the dual identity of algebra and geometry, it becomes a meeting point for middle school mathematics knowledge and becomes a medium for associating multiple knowledges. Therefore, The intersection of analytic geometry and vector is the inevitable trend of the new college entrance examination proposition. The following gives a few examples and hopes to attract attention. Example 1 (2 0
