What are the unit vectors along the negative x-direction, negative y-direction, and negative z-direction?

Text Solution

Verified by Experts

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`
