00:02
So we're looking for all of the angles that share a terminal side with pi 2.
00:09
So graph we have pi 2 here.
00:14
So this is our terminal side.
00:18
And if you want all the angles that share a quarter side with this, right, we make full rotation.
00:28
That's 360 or in terms of radiant, it will be 2 pi radiant.
00:35
That will get us the same terminal side as pi over 2 or we could do counterclockwise.
00:41
So we can start here and move the opposite direction and that's still 2 pi but negative 2 pi.
00:52
So you can create a table.
00:59
You can work with non -negative ends.
01:04
So we start with 0, start with then 1, then 2, and then 3.
01:11
So here, if i don't rotate, i remain at pi over two...
