If you do, the unit vectors are called i prime and j prime, the components of the vector change.
如果这么做,单位矢量就是 i' 和 j',矢量的两个分量也会发生变化
Here is the unit vector i prime, that's unit vector j prime and here is this vector A.
这是单位矢量 i',那是单位矢量 j',以及这是矢量 A
i and j are unit vectors in the x and y directions.
和 j 分别是 x 和 y 方向上的单位矢量
i prime and j prime are now rotated unit vectors.
' 和 j' 是旋转后的单位矢量
