How about just using
Cosh(x)=(1/2)(e^x+e^(-x))
And solve for e^x and then for x?
Just a thought

Good afternoon,
I've got a problem calculating "acosh". I have to calculate cosh^(-1) of
a very large complex number (-7.2718e+15 + 1.3382e+15i). If I try to
calculate the value of acosh on the command line of octave, the result
is "Inf". If I've got the same in a script, the script apparently uses
this "result" for further
calculations and I'm very suspicious about the output from this
script. Is
there a limit for the value that one can use when evaluating acosh???
Thanks,
Hana.
