What's the hyperbolic cosine of 'vice versa'?

Just thought I'd up the nerdity for a bit. :D

1. Dearheart, ZN...

It's vice versa, not vise versa :hi:

Vice is Latin in origin, and means "next to".

Versa is also Latin in origin, and means "to turn".



So in Pig Latin it's

Ice-vay Ersa-vay!

meaning, "When pigs fly!"





:rofl: :rofl: :rofl:

2. Shit! I knew that, I just wasn't paying attention.

Oh, well. :shrug:

3. Here is a way to approximate it. The cosh (hyperbolic cosine) is

defined as cosh x = (e^x + e^-x)/2.

Since we are doing vice versa, the other way around, we switch the signs to get (e^-x - e^x)/2. This is -sinh(x) by inspection.

Note that a person with vice is usually a zero. In this case cosh(vice) = cosh(0) = 1.
