There is a worked example / explanation on the worksheet, as well as a unit circle. The worksheet is in two slightly different formats: each has the same questions but with different unit circle diagrams. I have also included 6 different diagrams of the unit circle. I made a few, as I couldn't decide which liked best.
This is a no nonsense, straightforward neatly presents worksheet that can be used as an in – classroom exercise, practice for a test or even as a test itself.
