[SOLVED] find d/dx of hyperbolic function 1. The problem statement, all variables and given/known data Find: http://www.mcp-server.com/~lush/shillmud/1.1A.Q.JPG 2. Relevant 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 3. The attempt at a solution http://www.mcp-server.com/~lush/shillmud/1.1A.A.JPG Can this be further simplified? When I run it in maple I get: http://www.mcp-server.com/~lush/shillmud/1.1A.C.JPG 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?
