向量知识是高中阶段的一个重要知识点,是代数与几何相结合的产物,解决几何问题时更具有代数的特点.尽管向量方法在解决解析几何问题时写起来依然比较繁琐,但是它的解题思路与传统方法比较显得更直接,所以有利于学生掌握.下面就解析几何中比较常见的长度比值问题的向量方法与传统方法做比较并进行探讨.
Vector knowledge is an important knowledge point in high school, is a product of combining algebra and geometry, and has the characteristics of algebra when solving geometric problems.Although vector method is still cumbersome when it comes to resolving geometric problems, its solution Compared with the traditional method of thinking is more direct, it is conducive to students to master the following analysis of the geometric length of the more common problem of the ratio of the traditional method of comparison and to explore.
