平面向量作为高中数学的新增内容,有独特的地位,因为平面向量是可以用坐标表示的有向线段,对既可以进行代数运算又可以进行几何运算,这就为代数与几何之间的切换提供了一条新途径.下面举例加以说明.
The plane vector, as a new addition to high school mathematics, has a unique position because the plane vector is a directed line segment that can be expressed in coordinates. It can perform both algebraic operations and geometric operations. This is the switch between algebra and geometry. Provides a new way. Here is an example to illustrate.
