《高中数学》新教材第五章《平面向量》中的概念、性质、公式繁多,并且一些知识与平面几何的知识类似,学生在学习的过程中,较容易犯一些错误;本文试图剖析这些例子,避免同学们再犯同样的错误。一、对定义、概念理解不够定义是数学的基本细胞,用数学定义解题则是解数学题最基本、最有效的方法和途径,如果对它们掌握不牢固,理解不透彻,就会直接影响解题思路或解题结果的正确性。
There are many concepts, natures, and formulas in “The Plane Vector” of the new textbook “High School Mathematics”, and some knowledge is similar to plane geometry. Students are more likely to make mistakes in the process of learning; this article attempts to analyze these examples. To prevent students from making the same mistake again. First, the definition of concepts, not enough understanding of the concept is the basic cell of mathematics. Solving problems with mathematics definition is the most basic and effective method and approach to solve math problems. If they are not firmly grasped and not thoroughly understood, they will have a direct impact. The correctness of the problem-solving ideas or problem-solving results.
