e^(i*Pi) = 0 is cooler

0.9• = 1

might be missing a +1

yesh sry

Well e^iπ=cosπ+isinπ=-1 but an error of 1 isn’t so bad so it’s close enough

debatable
Andonno@lemmy.world 7 months ago
Not really.
1/3 = 0.3•
1/3 + 1/3 + 1/3 = 0.3• + 0.3• + 0.3•
3/3 = 0.9•
1 = 0.9•
And that’s only one proof, there are others.
lseif@sopuli.xyz 7 months ago
can 0.3• + 0.3• + 0.3• be really be added to equal 0.9• the same way that 0.3 + 0.3 + 0.3 = 0.9 though? and if so, is it proven or assumed? im not saying ur wrong btw, just asking. and does 0.000…001 equal 0?
Karyoplasma@discuss.tchncs.de 7 months ago
0.3• has infinte decimals, 0.0000…001 does not. No matter how many zeroes you put before the one, it will never be infinite, so it’s not equal to 0.
You simply cannot have “Infinity + 1” decimals, since infinity + 1 = infinity.

I’m not a math person at all, so I’m not really debating your proof, but it seems to me that if 0.9• = 1, then what does 0.1• equal? It “fits” perfectly into the “space” between 0.9• and 1, but if 0.9•=1 then 0.1• should equal 0, right? Except it doesn’t, because 0.1<0.1• and 0.1 definitely isn’t 0.
I definitely understand why some religious people think numbers are a tool of Satan.

It’s infinite ones - as you expand it, the illusion offered by the single digit disappears. 0.999 + 0.111 is 1.11, so 0.999… + 0.111… is 1.111…

That only works if you have enough nines.
Andonno@lemmy.world 7 months ago
That’s literally what the dot means. Infinite nines.

Do we have that many?

There is actually a global scarcity of 9’s but about 80 percent of the world’s 9’s are stockpiled in Nevada
