Hey, I have been absent from my math class for about 3 days and i have only a little idea what is going on. I have a test tomorrow and need to learn how to do this.

Can someone help me solve 1 example of every kind of problem and from then on i can study?

For example,

when given-need to find quadrant,reference angle,and EXACT value (no dec.)

sin 30---

cos 135---

sin3pi/4

cos5pi/3

csc4pi/3
