My Definition: Numbers that have a magnitude and a direction.
CAH: cos= adjacent/ hypotenuse
TOA: tan= opposite/adjacent
Pythagorean theorem: a(squared) + b (squared) = c (squared)
- a unit
Displacement is described
- an angle
- reference direction
- direction to turn away from the reference direction
