The first two links are notes with sample problems similar to what we did in class today.
Reference Angles Trig functions & Exact Values
These two videos are about the same thing. The presenter doesn't show the pattern we talked about in class to make memorization easier but he does give agood explanation of why it works. You will need to watch both videos: Exact Trig Values 1 Trig functions & Exact Values 2
We will have our first trig test on Thursday. You will be recreating the unit circle from scratch. You will need to be able to do today's material for Thursday's test. Also the requiz on logs and exponentials will on Friday.
