I understand that it depends on the compound angle formulas - I think the base of my difficulty starts with the fact that I don't know the compound angle formula for hyperbolics; I'm sure this would have an effect on what I'm looking to find.

Does anyone have a resource with the fornulas or could help describe it to me?

Thanks for your help :]
