Question

Unit circle question:

Find two angles, in radians, that represent the given point. Will draw picture

Answer 1

@amistre64 can you maybe help?

Answer 2

How dud you know it was pi/4? Why not something like pi/6? Is there a way to tell?

Answer 3

@Loser66

Answer 4

So I don't have to eyeball it and guess, it's just always pi/4 if its shown like that?

Answer 5

You just assume its in the middle and not slightly off?

Answer 6

@Loser66 Im just going to assume yes. What about the -7pi/4 answer you got?

Answer 7

you have 2 ways to move: counterclock and clockwise. Both start and stop at the same points and their value as I stated above.

Answer 8

So one last question then. Can I make this assumption?
