《考试说明》指出:“综合性试题以知识网络的交汇点作为设计的起点、着力点,力图实现全面考察数学基础和数学素质的目标。”向量由于具有几何形式和代数形式的双重身份,能融数、形于一体,既有代数的运算性质,又有几何的图形特征,因而它成为中学数学知识的一个交汇点,成为联系多项学科内容的媒介。
The “Exam Description” states: “The comprehensive questions take the intersection of knowledge networks as the starting point of design, and tries hard to realize the goal of comprehensively examining maths and maths.” The vector has dual identities of geometric form and algebraic form , Can melt number, shape in one, both the nature of the operation of algebra, there are geometric features of graphics, so it becomes a meeting point of secondary school mathematics knowledge, become a medium to contact a number of subject content.
