Vectors
Definition: Quantities that are fully described by both a magnitude and a direction
My Definition: Numbers that have a magnitude and a direction.
Formulas
SOH: sin= opposite/ hypotenuse
CAH: cos= adjacent/ hypotenuse
TOA: tan= opposite/adjacent
Pythagorean theorem: a(squared) + b (squared) = c (squared)
General Info
Described using:
- magnitude
- a unit
- direction
Displacement is described
- an angle
- reference direction
- direction to turn away from the reference direction
