This is the helpful picture that Schlake drew. It's a little confusing, sorry. Email me with questions. If you want to print it out, there's a link at the bottom.

So I hand-wrote a review using previous quizzes and homework. For the graphing bit of ch7, I did not include any fitting sinusoidal curves so you're on your own for that. I would review your own notes and quizzes also, because I sort of chose random problems. If you can't read anything, you can maybe email me and I can clarify, but probably not. Also I have not made a key, so tough luck. Because I made this, I won't be making a list of helpful links, so if you want, you can look at the previous posts on here. If you want me to email the pictures to you for whatever reason, email me.
The most important thing to remember when presented with weird things that you have to find the sin/cos/tan etc. for is that YOU NEED TO RELATE IT BACK TO THE UNIT CIRCLE.
For example: if you need to find sin(22.5) think about how you can get it to the familiar numbers on the unit circle. 22.5x2=45 so you can use a half angle formula and solve for sin(45/2) If you want to review the unit circle click the unit circle link in the sidebar.
