Well, it might be good to think of, maybe, the position vector, and maybe its variation.
这还是比较容易想到的,假如这是位置矢量,这是它的变化量。
Or, maybe I should insteadthink of it in terms of a position vector if it helps you.
也许我应该用位置矢量来考虑,如果你们觉得有帮助的话。
So, we want to decompose the position vector into a sum of simpler vectors.
故我们是把位置向量,分解为简单向量的和。
That turns out to be a very nice way to produce vectors, given one vector, the position vector.
这或许是一个得到矢量的很不错的方法,给你一个位置矢量
The most important vector is the position vector that tells you where the object is.
最重要的矢量是位置矢量,用来表示物体的位置
That's the analog of the position vector.
那是和位矢相似的情况
