Eeeeee

it ends in deeedee so maybe this is dexter when his sister has used the mosquito-izer on him and he’s angrily yelling at her
WhiskyTangoFoxtrot@lemmy.world 5 months ago
And then he murders her while maintaining his secret identity as a forensic technician?

This is a fantastic metaphor for what tinnitus feels like.

For some reason in my head, “eeeeeeeeeeeee de eee de e” is the sounds a toddler makes when you take them to a play ground and they just start to run in wide arcs - unable to decide which piece of equipment to play on first.
So, of course, the integral of “eeeeeeeeeeeee de eee de e” would be the sound of them sleeping the car on the way home.

Is nobody going to complain this is a screenshot of a Tumblr post of a Reddit post

You may just have made me create pattern screamer and I think it’s not exactly happy at you.

I can’t even upvote this; it’s too hideous.

That’s why I upvoted it.

"e", or Euler's number, is a constant used in maths because it has useful properties in logarithms and some other things. Basically just like pi except for logarithms instead of circles. Like pi, it's an infinitely long series of non-repeating digits. The crime you have witnessed in the post is a shitload of mathematical operations applying e to e in various ways in order to get (very close to) pi. Like saying "I'm going to make 14 using only 2" and then saying (2^2^2)-2, except instead of 2 and 14 you've got e and pi

Formatting messed up (on my client at least.) It’s
2^2^2, but it looks like(2^2)2(without the parentheses, of course.)mogoh@lemmy.ml 5 months ago
So it is not really approximating pi and there is no circle hiding?

Donno if it’s part of the joke but there is a beautiful equation:
e^iπ^+1=0
So once you allow yourself to use i and log and stuff, you get a nice and simple equation

They’re also doing some shenanigans with the variable of integration. I bet it would look a lot more palatable if they were changed
dogsoahC@lemm.ee 5 months ago
Not an equation though.

What is it?
A_A@lemmy.world 5 months ago
Could be the right hand side or the left hand side of an equation* or of an inequation** whatever.
(*) equations have “=” in middle
(**) inequations have “=<” (or …) in middle.WhiskyTangoFoxtrot@lemmy.world 5 months ago
I’ve never seen one before - no one has - but I believe it’s a white hole.

Gonna need the code to decipher that one 🤣

Look, I tried to solve this with Wolfram alpha, desmos, and nunerical integration in Python, but what does a subscript e even mean?? None of the methods I tried even returned a solution, which is kinda unsurprising…how do you integrate with respect to e, when e isnt a variable??

Psst, remove the space between ] and (
zkfcfbzr@lemmy.world 5 months ago
Kind of intentionally obtuse since they used eₑ as a variable and eₑₑ as another variable, and used (e-e) as an exponent a few times, which is basically the equivalent of multiplying by 1 in a fancy way.
The same integral written in a saner form is:
integral from -e^e to e^e of (integral from -e^e to e^e of (e^x*e^(-y^2-x^2)*e^-x)dx) dy
xthexder@l.sw0.com 5 months ago
Wait… that’s not an approximation at all! That equals exactly pi. If I understand the math correctly, it’s effectively a formula for the area of a unit circle.
OrganicMustard@lemmy.world 5 months ago
That should be an approximation. To get exactly pi the range of both integrals should be from minus infinity to infinity like this. It’s the integral of the 2D Gaussian, which is fairly known.
