• Word problem strategies with right triangles and trig
• The definitions of trig functions anywhere in the plane

• I don’t think the topic ordering from the textbook makes the most sense. We’ll be jumping around a little bit in this unit. You probably will need to look back over these handouts several times to pull all the ideas together. (You may also want to read the book from the “Read It” links on WebAssign.)
• Here are a couple harder problem setups we can’t cover in class.
