Yup, our final is coming up and our teacher told us that one of the four identities she gave us would be on it, so I want to make sure I have these right.
I think it's right, and it checks...so yay?
I can't seem to get it any farther without it not checking out. I cancelled out the sine's, leaving me with (1-sinx)/(cosxsinx) But it didnt check in my calculator...oh, and those are supposed to be theta signs, even though half of them don't look like it. Heh.
