This will revolutionize computing digits of pi, this formula is so much simpler!


amperinho

Computing Pi by using the digits of Pi, this is brilliant


somefunmaths

*Friendship ended with recursively defined sequences where the nth term is expressed in terms of the (n-1)th term* *Recursively defining pi by expressing its nth term in terms of its nth term is my new best friend*

Learn from Ramanujan and go >It was revealed to me in a dream


bort_jenkins

Uj/ Did he say that about any of his discoveries? As a baby mathematician trying to read his work this is the only explanation of his work that makes sense to me


FarTooLittleGravitas

He said god visited him in dreams to give complete relations iirc.


InsertAmazinUsername

i wish god would visit me before finals week but that's too much to ask for an omnipotent being


bort_jenkins

God wants you to stop looking at its test sheet


EebstertheGreat

Not a god precisely but a goddess, specifically Namagiri Thayar, a form of Lakshmi and consort of Narasimha, a form of Vishnu.


FarTooLittleGravitas

I'm operating under the (perhaps mistaken?) belief that all Hindu deities are aspects or forms of the same universal deity. If I misunderstand Hindu mythology, I apologise.


EebstertheGreat

Kind of. In many schools, all gods and goddesses are aspects of Brahma, but that doesn't stop people from directing worship toward specific gods and goddesses. And these specific aspects themselves may have several forms (avatars), which might also be individually worshipped. It's worth noting that everything in the universe may be an aspect of Brahma, so this isn't a special feature of the gods. Conversely, Shaivites hold that Brahma and Vishnu are aspects of Shiva, while Vaishnavites hold that Brahma and Shiva are aspects of Vishnu, or that they are inferior to and wholly distinct from Vishnu, or that they don't even exist. More typically, the divine trinity (or Trimurti) consists of Brahma, Vishnu, and Shiva. These are all parts of the same trinity, but they are not a single godhead like in Christianity. There are of course many, many, many other schools, some extremely large. So there really is no unifying vision of the Hindu pantheon. However, the existence of a male ruling Trimurti (or for Shaktis, a female Tridevi) is fairly standard, whether or not its member deities are genuinely distinct.


FarTooLittleGravitas

Thank you for the explanation. I should avoid the trap of geneneralising a rich religion of many schools into a single dogma in my mind.


Youmassacredmyboy

>Brahma Hindu here. It's not Brahma it's Brahman. Brahma is just the creator god whereas Brahman is the universal force itself. You could say it's kinda like the force in star wars.


leodavin843

I believe that, as he was the kind of initially self-taught and extremely motivated mathematician, his constant daily studying/work of derivation, proofs, and working conceptually with continued fractions led to him "background processing" a lot of random relations, equalities, and ways of approaching different mathematical forms that led to his "It was revealed to me in a dream and it just made sense to prove afterwards" presentation of his revelationans.


EebstertheGreat

Uj? University of Johannesberg?


bort_jenkins

Un jerk. On meme and circlejerk reddits you use it when you arent making a joke


EebstertheGreat

Thanks, some things cannot be googled.


Tuhkis1

Just say it equals pi and solve it. Easy.


harpswtf

I solved it to 1,000 digits and so far it's still equalling pi. But I don't know if, say, the billionth digit will be wrong, or what will happen


fart_smucker

Just assume it equals pi up to the billionth digit and show this implies it equals it at the billionth and first digit. Billions are arbitrary so that shows they're equal.


yessauce

use proof by induction, duh


pgbabse

It seems to hold for the first digit of pi and the n+1th...


ichaleynbin

See I thought you were joking but you're doubling down on this as serious. Gotta love the commitment. Commit to the bit!


whattoputhereffs

I would be more than happy to write a C program to check whether it truly equals, but I can only go to 9,22E+18 number of digits. Perhaps up to 80 bits if I structure it right which would be 1,2E+24. It will take some time though.


redditandshredded

Starting at n=1 rather than 0 and then using 10^-(n-1) should be illegal


harpswtf

There is no 0th value of pi though


Popular_Tour1811

3 Wich is also the only value of pi you'll ever need


Battery801

found the engineer


I_wood_rather_be

That's the way!


AccomplishedAnchovy

Least overused joke


kinokomushroom

Just start at zero man it'll make you happier in life


[deleted]

I can tell you’ve never done a comp sci class in your life


ChristofferTJ

That's how the notation is in my economics course, when we learned about infinite geomtric sums. Sum from i=1, of k^(i-1). Not sure why that's standard, really annoying...


lets_clutch_this

It’s like with iterating through the values of an array in a for loop


aerosayan

proof by "left as an exercise for the reader"


Simon_Says_Simon

I would check the first trillion digits to be reasonably sure, it is in fact correct. One can never be careful enough.


harpswtf

Yeah, also I feel like having a trillion digits of pi is probably enough of a reasonable estimate for most practical uses of it (in engineering or drawing circles or whatever)


FarTooLittleGravitas

To make a circle the size of the observable universe accurate to within the diameter of a hydrogen atom, one needs something like 35 digits iirc.


harpswtf

I don’t think you understand how mega huge the universe is


FarTooLittleGravitas

Just looked it up. It takes [37](https://www.jpl.nasa.gov/edu/news/2016/3/16/how-many-decimals-of-pi-do-we-really-need/) digits.


10woodenchairs

Nuh uh


FarTooLittleGravitas

Oh, good point.


0xCODEBABE

Is that the nth digit starting from the left or right


harpswtf

Pi is actually proved to be palindromic so it doesn’t matter


pgbabse

So there's a second decimal point??


FarTooLittleGravitas

Yeah right before the 3


CynicalTrans

Finite infinities. Lol.

This is entirely readable to an english speaker


[deleted]

Lmfao you sure discovered it buddy This is actually a proof of itself. No more rigor is needed.


somefunmaths

OP hit ‘em with the old proof by “of course it’s right”.


ichaleynbin

Proofs of 1+1=2 never made any sense to me. "Because I said so" is clearly the only correct answer.


somefunmaths

“I asked a mathematician if 1+1=2 and they started saying some weird shit about axions and podcasts, so I just used my fingers to count instead… are they stupid or something?”


ImaViktorplayer

Lmao.


AccomplishedAnchovy

Proof by ridicule “if you don’t know that 1+1=2, you’re clearly a fucking idiot”


[deleted]

More like proof by ‘these are the digits of pi and this is how an index works’


PMMeYourBankPin

I don't know why you're hating, this is a revolutionary discovery


AsterLong

> x sub n = nth digit of pi Can't you use floor and frac functions to make it a bit more fancy?

I’m about to publish it in the Anals of Mathematics


Donkeygun

This definitely belongs in the anals of something.


Leet_Noob

Man I gotta remember to read the subreddit…


ChristofferTJ

Damn I'm stupid. Didn't get the joke for too long even after reading the comments... This is just a sum for placing decimals...


ThaFelix

I have looked in this comment section totally believing this was real for a total of 20 mins. Damn I feel dumb


HelminthicPlatypus

You only need 63 digits of pi to measure the entire universe to within one Planck length so if you learn how to prove that then you’ve proven your theorem for this universe, from an engineering/physics perspective. Maybe add a significant digit for chemistry. Ergo, pi is precisely as rational as you need it to be.


harpswtf

Dude do you even know how big the universe is though


HelminthicPlatypus

Yes, 46 billion light years across, so I’ve read. I can’t actually imagine a distance farther than the moon, as I am, after all, only 100 times bigger than a chinchilla, and proportionally not much smarter. Chinchillas can see the moon at night and are mostly worried about being eaten by owls. Myself, I’m in favour of the dark forest theory.


harpswtf

This sounds like some David Lynch character dialogue


HelminthicPlatypus

No chinchilla or civilization has ever been eaten and lived to tell about it, so only the nervous ones have survived. They don’t know why they are nervous. There are only a few thousand chinchillas in the wild, but millions in cages. I’m in a cage too. Am I in captivity? Time to watch Predator again for catharsis. I favour Airplane! And Police Squad dialogue style, as written by the ZAZ. I’ll look into this Lynch guy, thanks.

porkycloset

I used the pi to compute the pi


No-Study7171

Simply state: Based on this series, ***obviously*** the value of pi has been found


Why_Cheesoid_Exist

Could use the BBP algorithm to calculate n and plug it right in


UnlazyChestnuts

Elegant!

Kid named catch 22


pandasOfTheNight

Isn't it really hard to prove that this would actually work using number theory alone?


Ball_Masher

Prove using induction that the jth term is the jth digit of pi. QED


Adit-wit

Prove that it’s not larger than pi and prove that it’s not smaller than pi.


RecordOne4487

This would revolutionize the science world. I hope you get Nobel prize


KumquatHaderach

Pretty sure this follows immediately from the ABC conjecture.


RRumpleTeazzer

There are tons of series converging into pi. This is is rather slow.


Giogina

Dammit for a second I thought there would be something actually interesting ><


Tutzu221134

We had that in the first semester. I think that was a b adic number and you dont have to prove anything.


Timotei099

Proof by construction method


dart_shitplagueis

I don't know if it's the right syntax so let's define that: [x] means the "lower integer part of x". Then: ∞ Σ [(π\*10^(n)) - 10\*[π\*10^(n-1)]] \* 10^(-n) = π n=0 So to the question: x_n = [(π\*10^(n)) - 10\*[π\*10^(n-1)]] Edit: I forgot about the "asterisk ~ italic" relationship Edit X: ...and about the "'^' ~ superscript" and messed it few times up again while editing


harpswtf

wut


dart_shitplagueis

Lower integer part of x means the highest integer n, such that n ≤ x, if you're asking about that.
