You can put this solution on YOUR website!
You know that
is a full circle and brings you back
to the zero angle
------------------
Knowing also that
This becomes
So, is the smallest positive
angle that is co-terminal with
=============================
You had to go in a negative ( CW ) direction
to get this angle. You know that:
Is a fill circle. You just went in a negative
direction to get there.
---------------------------
Likewise,
This becomes
----------------------------
Now you just have to convert this to a positive
angle. If you went and then backed up that would be the same angle, so
I can say:
So, no I can say:
