向量作为一种“工具”进入中学数学教材,占的比重虽然不大,但是其作用非常之大,为解决问题提供了全新的、重要的数学方法,有些复杂的问题利用向量来处理就会化繁为简。牛顿曾说过“对于数学,有时例子比定理更重要”。本文主要是通过一些例子说明向量垂直在解题中的几种应用,以供读者参考。 Vector as a “tool” to enter the high school mathematics textbooks, accounting for the proportion of small, but its role is very large, to solve the problem provides a new and important mathematical methods, some of the complex problems using vector to deal with Will be complicated. Newton once said “For mathematics, sometimes an example is more important than a theorem.” This article is mainly through some examples to illustrate the vector vertical in the solution of several applications, for readers reference.
