How to find the reference number for each value of t.?
How can I find the reference number for each value of t in the context of the unit circle? Specifically, for the following values: a) t = 3, b) t = 6, c) t = -3, and d) t = -6. I would appreciate an explanation of how to approach this problem since it does not involve pi. Thank you!

If t is in radians, since 3 is > π/2 but < π, it is in quadrant 2 so subtract it from π: π - 3
6 is between 3π/2 and 2π so it's Q4 so subtract from 2π: 2π - 6
-3 would be the other way around so in Q3; add it to π: π - 3
and -6 is the other way around too so in Q1; add to 2π: 2π - 6
Maybe anyway, see what you think
