向量的优势在于它可以把逻辑推理问题变成简单的纯计算问题,解题方法直观并且容易理解。在解析立体几何、平面几何、三角函数中,向量起着很大的作用,它为我们提供了一种新的解题思路,简化了我们以往做题所需的烦琐步骤,但在解题过程中经常会出现一些审题或解题失误,本文举例加以分析。 The advantage of a vector is that it can turn logical reasoning into a simple pure computational problem. The problem solving method is intuitive and easy to understand. In the analysis of solid geometry, plane geometry, and trigonometric functions, the vector plays a large role. It provides us with a new solution to the problem and simplifies the cumbersome steps we used to make questions in the past, but in the process of solving problems. Some trial questions or problem-solving mistakes often appear in this article.
