Find the reference number of t = 3.3?
------------------------
Reference number is the shortest arc length from Pt to the x-axis.
-----
Your angle is stated in radians which are hard to imagine.
----
Change to degree measure to SEE a way to the answer::
3.3(180/pi) = 189.07 degrees
-----
In degrees the reference angle is 189.07-180 = 9.07 degrees
------
Writing that in radians you would get (3.3-pi) radians
