SOMEONE ASKED 👇
How to find the reference number for each value of t.?
HERE THE ANSWERS 👇

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
