- Co-terminal angles will always end up at the same place (exact same terminal angle), only one runs cw and the other ccw
-S=Theta(r)--------(S=arc length, Theta=inside angle, r=radius)
- Unit Circle implies the radius at any point along that circle is 1 unit long
- sides x and y on the unit circle are easily calculated using simple grade 11 trig or Pythagorean theorem
- cos=x, sin=y (x,y)
- The hardest part is just understanding that the circle isn't just something to be memorized, it is actually to the contrary very logical and can be be thought of as just fractions
