What are the unit vectors along the negative x-direction, negative y-d

1.	What are the unit vectors along the negative x-direction, negative y-direction, and negative z-direction?
Answer» Solution :The unit vectors along the negative DIRECTIONS can be shown as in the following figure. Then we have: The unit vector along the negative X DIRECTION `-=hati` The unit vector along the negative y direction `=-HATJ` The unit vector along the negative z direction `=-HATK`
