Description: Value of the named sinh function. Here we show the simple conversion to the conventional form used in set.mm, using the definition given by df-sinh 47264. See sinhval 16041 for a theorem to convert this further. See sinh-conventional 47270 for a justification that our definition is the same as the conventional definition of sinh used in other sources.
