yeah, I just thought there was a general name for the level of derivative regardless of what it was measuring

Not that I know of, there’s special names for the first, second, third, fourth, and fifth for position, and I assume other functions that come up a lot too.

As a number theorist this stuff didn’t come up much for me :)

Anyway, for Coronavirus you’ve got number of dead, then the first derivative of that is number of deaths per day, then the second is change in number of deaths per day per day, then the third would be change in the change in number of deaths per day per day per day.

So if a value is getting bigger then its derivative is positive, and if its getting smaller then its derivative is negative. Obviously the total number of dead can’t go down so the deaths/day is never going to be negative.

Finland had a -1 deaths day at one point just before Easter according to worldometer.

I mean that does sort of imply it's becoming the actual zombie apocalypse, but only in Finland and only very slowly

It's only the actual number of deaths (the "zeroth derivative") that can't go down, the first derivative (the number of people who die every day) obviously can

It just can't do below zero itself, sans zombies

Ah yeah I was confused briefly, it's true it can't be a negative number
