Theorem sinhval-named 42477
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 42474. See sinhval 14884 for a theorem to convert this further. See sinh-conventional 42480 for a justification that our definition is the same as the conventional definition of sinh used in other sources.
