Holy Crap, I had solved all the Negative Sign TRIG Functions, dealing with the negative angles, and didn't mention the TRIG Negative Formula Rule, where, for every Trig Function but Cosine and Sec, you can just solve for the Postive Sign and then Flig the sign on your solution... basically f(-x)=-f(x). the Cosine and Sec are an easier EVEN f(-x)= f(x)
