Normalize: g = ( -3, 4, -1)T
| g | =(9 + 16 + 1 ) =
26 gu = ( -3, 4, -1)T / (
26)
The following represents a unit vector oriented at 45o:
(1, 1)T / (2).
The length is ( 12/2 + 12/2 ) = 1.
The angle is arctan(1/1) = 45o.
How would you make a unit vector that is pointed in the opposite direction?
Negate each component:
-( 1, 1)T / (2) = ( -1, -1)T / (
2).
