I really do understand trig, I just have to take the initiative to study it all.
First:
sin= y/r csc=r/y
cos=x/r sec=r/x
tan=y/x cot=x/y
r=√x^2+y^2
*csc, sec, and cot are opposites of sin, cos, and tan.
*they are used to find θ, an angle measure. (unit circle)

Second:
Trig chart.
It is pretty self explanitory. MEMORIZING it is the hard part. Using it is pretty simple.

Third:
Reference angles.
1. find which quadrant the angle is in.
2. determine the sign in that quadrant
3. subtract 180° until the angle is between the absolute value of 0° and 90°

e.g. Find the reference angle for sin210°
1. lies in quadrant 3
2. sin is negative in quadrant 3
3. 210-180=30
sin210°= -sin30
you would then look to your trig chart and find a reference to sin 30 (π/6)
sin 210°=1/2

I pretty much understand everything. I just need to keep studying. If I have any questions, I'll be sure to ask on Monday.
