First Unit in Precalc-Trig - Jacob Evenson

I didn't really have a tough time with the first unit.  However, I did enjoy re-learning the Unit Circle, because I had completely forgotten what it was, how to use it, etc.  Perhaps the most difficult thing for me was remembering that co-secant was the inverse of sine, not cosine.  The same was true with secant, where I kept thinking it was the inverse of sine instead of cosine.  Eventually I started remembering it, then everything became incredibly simple.  The only thing I'm not sure on is the clock problem, because I got that wrong on the test.  (Still need to ask Jackson about that, marking it on my to-do list now...)
