I took a bunch of comments I got on my previous post and used them as a hatchet on my trig lesson. Pared it way down - less angles, took out tangent, made the problems easier, didn't give away the store. I suspect it's going to work much better next year. I wish I could teach it again, now. But unfortunately we have to fix the plane while we are flying it. (Maybe I can talk one of my colleagues into letting me take over their class for a day...hm.)
Here is the important part (links to download complete docs at the end):

Thanks again, all my collaborators. You're the best around.
