b.o.b muddiest point- identities

My muddiest point for this unit was verifying identities. Simplifying was very easy and finding the exact value in radians was fairly simple, but the verifying I found difficult. Mainly the ones having to do with tangent though. Those really through me off, I don't know when my exact moment of clarity with that was, maybe when I was doing the review but I still found that the hardest part throughout this unit.
