Hi

I have a question about the integration formula of cosecant which leaves me puzzled.

I usually find it written as " = ln |csc x - cot x| + C" in most manuals, but sometimes it is written as "= - ln |csc x + cot x| + C" or "= - ln (csc x + cot x) + C".

Why is that? Can they all be used?

Thanks a lot
