[Maxima] demoivre and hyperbolic functions

[Raoul]

Hi all,


This works fine:

(%i10) exponentialize(cos(x));
(%o10) (%e^(%i*x)+%e^-(%i*x))/2

(%i11) demoivre(%);
(%o11) cos(x)

but this does not:

(%i12) exponentialize(cosh(x));
(%o12) (%e^x+%e^-x)/2

(%i13) demoivre(%);
(%o13) (%e^x+%e^-x)/2

Is there a function that can do what demoivre does
for trigonometric function?
