1. If I'm being perfectly honest, I did not do much studying. I forgot to do the vocab and did no outside of school work. The only real way I studied was by scanning the material 10 minutes before class.
2. I don't think there's anything I'd do differently. The only thing I would do differently is I'd remember to do the vocab.
3. It was not difficult. I got a 92, and that wasn't too hard, as evidenced by my clear lack of preparation.
17. Arctan -1 = 7pi/4
18. tan(Arcsin 1/2) = tan pi/6 = (square root of 3)/3
25. sinB = y/r tanB = y/x
x=r at 0 and pi
sin 0 or tan 0= 0 + 360k where k is an integer
