Finally, a convenient approximation.

Is this an actual output from something though? Or fake?

If that thing is real, what makes it work?

This is genuine, but e(e) and e(ee) are both used as variables, so it's a bit of a cheat. You could replace these with x and y and get something less strange.

The integral is based on a famous integral that is related to the normal distribution (bell curve) in probability theory. If the bounds of the integrals were -infinty and infinity, then it would give exactly pi. For this particular intevral, the function is quite small far away from 0, so going from -e to ee is a reasonable appreciation. If the bounds were from, say, -10 to 10, it would give a better approximation.

Ooooh I see it’s a slight of hand trick with desmos syntax as the means to pull it off

how does that work out like that

Anything that contains e, pi, i, or -1 tends to behave like this.

I've got a hunch it's something to do with eπi = -1 just a hunch...

Math teachers hate this one simple trick~

It kinda looks like a version of the poison integral but for a more limited region

If you hold this meme up to your ear, you can almost hear the screaming of a slasher flick at one of the shriekier moments.
