My HP-15C that I keep in the drawer between this keyboard and monitor
does have arccosh. I used to keep XACT on my packet computer, it
emulates an HP11, I think. Runs in DOS. The scientific mode calculator
that came with Fedora Core 3 gets the same answer of 158.0349 ohms Zo
for 1/2" conductors, with 1" center to center spacing.
Google's calculator doesn't seem to know arccosh. Too esoteric, I guess.
I just checked, according to the doc for x11.exe it will do inverse
hyperbolic cosine and seems to have a windoze icon in the package so
maybe it even runs in windoze. The complete XACT directory is about 1/2
MB on my dos packet back up disk. It should shrink if compressed. It seems to
be available on line, google xactcalc.
