I don't know how much of this work you can just do in your head.
00:04
But let me give you a synopsis of this.
00:07
That 7 pi over 6 is over here.
00:11
And it's not even that big of a deal if you know where it ends.
00:15
But we are going counterclockwise, excuse me.
00:20
So if you want the negative co -terminal angle, they're basically asking for this.
00:25
Well, how do you get there? just imagine for a second you went counterclockwise.
00:28
Well, what kind of, it's a revolution, but by going clockwise, what you have to do is a full negative 2 pi revolution.
00:42
So imagine that you went counterclockwise, 7 pi, 5, or 6, and then subtract off 2 pi, and you'll get the right answer...
