Hey folks! I've just learned about Hyperbolic functions, and I've got a question type here that I haven't seen done before if anyone could lend me a hint.
I must be having a bad math day, it seems like it should be easy, but I just can't figure out where to start. If I set , I'm not too sure where to go from there to see what is equal to short of solving for which looks like a mess. I had a friend tell me to use trigonometric relationships (like that between cosine and sine), but I'm not so sure that this relationship works in the same way, does it?If , find the value of the other hyperbolic functions at .
