You lost me at inverse hyperbolic cosine.

OK, I remember Complex Numbers from my Degree 12 years ago. But not much more...

Is this a maths, or a programming problem?

Take the math out of the code. I would but I'm on my bb and I'm to lazy to not copy n paste.

Complex numbers is not a coding reference just numbers with decimals and exponents imo

From what I gather..
http://www.wolframalpha.com/input/?i=Re(-arcsin(z)%2Bpi/2)*i%2BIm(arcsin(z))
Later on that page says it's equal to
i*arccos(z)

Graphing that
http://www.wolframalpha.com/input/?i=i*arccos(z)
versus
http://www.wolframalpha.com/input/?i=arccosh(z)

You can see the real is just flipped above one.

They clearly aren't equal.
http://www.wolframalpha.com/input/?i=arccosh(z)%3Di*arccos(z)

So I can't put any reasoning behind it, but I guess your formula's just wrong; I figured I'd post what I entered anyway.
