## Main Question or Discussion Point

Hi, I am trying to understand solving boundary valued partial differential equations and it's relation to hyperbolic functions. In one of my problems, there is a PDE and the solution contains the hyperbolic function "cosh". I was just curious if anyone has any information for me to read up on this, I cannot find anything in any book that gives any relation of the cosh function to solution to PDEs. Thanks.
