This is like:
What breed is the dog owned by the owner of the dog who is a Pekinese?
It reads:
The angle whose Sin is the Sin(-7pi/6)
It remains to show that

Now going radians more, I get a positive
The Sin of this is positive, so I guess you can say it's the same
as an angle of . I sort of question it, but maybe it's
OK. Why isn't a better answer?
