高中数学新教材增加的向量知识 ,有利于沟通几何与代数之间的联系 ,为解决和处理中学数学中的问题 ,增添了新的方法 .可将几何问题中的逻辑推理转化为向量的代数运算 ,使问题的解决显得更简洁和清晰 .然而 ,一方面 ,高中新教材没有摆脱老教材的阴影 ,很多问题用向量研究更简单 The added knowledge of vector in the new textbook for high school mathematics is conducive to the connection between communication geometry and algebra. It adds a new method to solve and deal with the problems in middle school mathematics. It can transform the logical reasoning of geometric problems into algebraic operations of vectors. , make the solution to the problem appear more concise and clear. However, on the one hand, the new high school textbooks do not get rid of the shadow of old textbooks, and many problems are easier to study with vectors.
