I am wondering if moving to infosec.exchange may be called for.
I'm switching from a civil service #cybersecurity#policy position to an #ISO function implementing #NIS2 and related directives at a critical infrastructure company in a couple months. Got some new skills to learn, but would still get wound up about #Politics, #disability and #GLBT rights.
The usual name for inverse hyperbolic sine function is
arcsinh 𝑥
Now some Wikipedians have decided to start calling it
arsinh 𝑥
I've never seen this before and it makes me think "arse". I don't like it!
A more common alternative is
sinh⁻¹ 𝑥
Some computer scientists use
asinh 𝑥
Some pedants, claiming that hyperbolic trig functions aren't connected to arcs, argue for
argsinh 𝑥
Who came up with "arsinh" and why? Is it too late to kill off this notation? It seems like a case of Wikipedia editors run amok. It reminds me of how some of them made up their own very precise definition of "order of magnitude" - and now run around correcting people who say "to within an order of magnitude" if it doesn't match their made-up definition.
When I want to be understood I'll use "arcsinh". When I want to act mathematical I'll use "sinh⁻¹". If I wanted to save space I'd write "asinh". I might use "argsinh" if I were pretending to be a pirate. But I'd only use "arsinh" if I wanted to be an arse.
By the way, I don't like debates about notation. So I don't know why I'm talking about this when I have more interesting things to talk about. Just blowing off steam, I guess.
