Half in jest  and therefore half seriously. Of course I can easily
form cosh, sinh etc out of exp but it would be nice to have them
builtin. It would be good to check elaborate 'trigonometric'
simplifications (does 'trigonometric' apply to hyperbolic functions?) at
general values of variables rather than values specially chosen to ease
the calculations.
