    How do you find the average of angles. There is a hint in the question to use unit vectors but i'm not sure how. Could someone give an example to explain how. Btw you cannot just add them up and divide by the number of angles as averaging 359 and 1 gives 180 and not the expected 0. Thanks, Jon

    Well, if you don't know how to find the unit vector for an angle, you basically need to tell your teacher, because the question obviously assumes you do know.

    I will give hints about how to solve a question. I'm not going to be a substitute teacher for things you're supposed to already know. Not least because your teacher will (a) do a better job and (b) needs to know if you don't know something that you're supposed to.
