trig functions as ratios of sides of a right triangle
trig functions as the coordinates of a point on the unit circle
what is a unit circle
how to use sohcahtoa
what are radians
how you can have a sin or cosine of an angle greater than 90°
what does a negative angle mean
what is a coterminal angle?
how do you find the coterminal angle within the range 0 to 2\pi?
how to convert from degrees to radians and from radians to degrees.

ive got this
i'm fuzzy
i am so confused
