Hello. I am given various take-home tests throughout the semester in my Trigonometry class. I'm usually pretty good at remembering new material, but I'm having a lot of trouble remembering how to do the older problems from earlier in the year.

If someone could please refresh my memory and help me understand how to solve these questions, I would be very grateful. There are quite a few questions, so I apologize. The ones I am in need of assistance on are boxed. The last page is all questions that I don't really know where to start with. Thank you in advance!
