comment Expansion of Expression
I get the fully expanded result with ExpandAll: ExpandAll[TrigToExp[Exp[-l H] Sinh[l (H - h)] Sinh[l x]]] gives: -(1/4) E^(-h l - l x) + 1/4 E^(h l - 2 H l - l x) + 1/4 E^(-h l + l x) - 1/4 E^(h l - 2 H l + l x)

comment Expansion of Expression
Thanks, that did answer the question I asked. But when I tried: Simplify[TrigToExp[Exp[-l H] Sinh[l (H - h)] Sinh[l x]]], I get: 1/4 E^(l (h - 2 H - x)) (-1 + E^(2 (-h + H) l)) (-1 + E^(2 l x)). Is there a way to have this completely expanded out?

Thanks to you and @Jens for clearing up my confusion on declarations.

Thanks, I thought that the declaration of the variables as Reals would be automatically incorporated in subsequent calculations, but I understand from your response that it should be formulated as Assumptions and have calculations specifically invoke the Assumptions. I hope there is a way to have substitutions made so that the numerator is recognized as the first element of the vector rhatV and the denominator as rhat^3.
