What is the physical relation between any two points inside the velocity vector-space?
Find a unit vector which points directly halfway between the directions of the two vectors A=5X - 3Y and B=4X -7Y +5Z .

1 速度向量空间中两点的物理联系是什么?
以这两点为端点的向量是这两个速度之差
2 找到一个单位向量其方向指向A=...和B=...中间
先找到A方向的单位向量a=(1/根号34)*(5X-3Y),根号34是A的长度.同理得到B方向单位向量b,a+b就是A和B方向的中间,再除以根号2即a+b的长度,就可以得到所求向量了
第一句:在速度向量空间中任意两点间的物理关系是什么?
第二句:找到一个单位矢量可以直接标示向量A和B的方向的一半
