Explain how I can solve these trigonometric equations?
Ok so I'm used to solving these with a usual triangle... not by themselves. Can someone please explain to me how I can solve these?
1. Sin(5Pi/4)
2. Cosin(4Pi/3)
3. Tan(7Pi/3)
4. Csc(300 degrees)
Okay so I just looked at the problems again and it said that I have to use the unit circle to solve this. How do I do that?

There is nothing to solve here. Write down the exact statement of the question.
Update:
-Well, it's still a little unclear. Are you supposed to find the real number values of each of these? I don't know if you're allowed to use a calculator, but if not, are you supposed to use a protractor and stuff to measure lengths and angles on the paper?
-Anyways, I need to sleep. Here's a little sketch using all the info you provided. I'm not sure what they're asking you to do, but hope it helps.

on your calculator...
1) do 5 Pi divided by 4
2) do 4 Pi divided by 3
3) do 7 Pi divided by 3
4) type in cosine -1 ( do the inverse of cosine) 300
