general

although if you could make one that is 0/1 for whole numbers but continous between them

that would be a little cool at least

as d -> infinity, this will look more and more like what you want

that looks like this with d=100000

but when you zoom in its clearly not exactly what you want

this demonstrates the dynamics of the problem though

so full marks

what do you mean by 0/1

do you mean 0 or 1,

something like

for every whole number besides 1 it's 0

feels like that would be possible

but it can be continous inbetween

so f(2) = f(3) = ... = 0

but f(1) =/= 0

well f(a) =/= 0, meant 1 as in one of the numbers

oh you are saying, for all integers except one integer a, f = 0

okay

uh

I am struggling to think of an example that would work for that. It cannot be a polynomial equation (except if you allow for an infinite polynomial)

for example

like, this would be zero for all positive integers greater than 1

I thought you made a penis there for a second

oh wait

i was asking about that because someone else I asked had come up with something

but turns out they cheated and used an infinite product

yes

that makes more sense

the graph of what I wrote is actually kind of ridiculous though

that is this

if you allow infinite sums instead of infinite products, and accept all integers being zero

taylor series for sinx but replace x with pi x

but I don't think there is a finite way to ensure it holds for all whole numbers

pirate why did this topic come up

there's a person in another server who asked me for 'ridiculous math problems'

the first one i gave was

actually the month/day/year thing from here

that one was fun

they ignored leap years so they were off by a bit

I ignored them too

interesting

leap years are a pain to code around

they said 26.9% of days would be unique

let me get my code

while yours was 29

iirc

oh you had that saved

still i wonder which one is the most accurate

I only ran it from year 1 to 2020

it depends what range they ran it to

Okay I ran it from 1 to 5000 and got 29.15

they also said they used doubles in java

so might have been floating point errors

the 1 to 2020 one was 29.12

anyway so they did that one

and asked for more

the second one i said was similar to this but

instead of checking if x = a, it's if x is within a given arbitrary range

I mean, if they want esoteric math problems

they can just do my rings assignment for me

there tell them to do this

alright

consider it done

you can pay them in loli's

is this a math major

all i know about their education is that they're failing every class apparently

but i'd assume so

lmao

based

they binged log horizon and asked me for random questions

instead of doing any studying or work

update I finished that question I posted

lol

the answer was <x-1>

Spooky, I know you talked about how stupid the "suicide" posts are, you can tell its midterm season because we just keep getting them https://old.reddit.com/r/uwaterloo/comments/lvtgtr/i_dont_think_i_can_do_this_anymore/
