I remember studying that equation in Freshman calc. As I remember, it's called "the yule log".
We don't use that term in the UK, in the UK secondary school starts at age 11ish, but I see freshman seems to be aged 14-15ish?
In that case I guess this has been around for a while, I just assumed it was something someone created a couple of years or so ago and that it then went viral.
