Understood, I just thought I might ask about this continuity issue since you mentioned in the other thread that all I needed was continuity to prove the PT from this approach. It seems like a very simple proof to say that sin(A+B) = sinC is the PT - but perhaps this is just a restatement of the same and not really a proof.

I was hoping I had at least done an adequate proof. But I will move on to other things if this all is trivial.

Thanks for the reply.
