**[SOLVED] find d/dx of hyperbolic function**

## Homework Statement

Find:

## Homework Equations

d/dx f(x)*g(x) = f(x) * d/dx g(x) + g(x) * d/dx f(x)

d/dx f(g(x)) = d/dx f(g(x))* d/dx g(x)

d/dx sinh x = cosh x

d/dx cosh x = sinh x

Can this be further simplified? When I run it in maple I get:

I'm probably going to be posting here often so let me give you a little background. I am beginning calc II by correspondence. It is the last course of my undergrad and I haven't done any pure math courses in a while. I think things are going alright so far but without a prof or fellow students I sometimes become stuck or find it difficult to check an answer in a way that allows me to move on to the next question with confidence. I thought maple might help me check my answers but in this case it's left me more confused. Thanks for reading!

P.S. How do I use special math characters (like infinite etc.) in my post as have seen some people do?
