[crystal delta]

How could Fläppers know of such a beautiful thing like Mitternachtsformel ❤

Callum I'm lazy c:

I have what I want O.O

[sudden panther]

Ban Catto and Casca. 😦

[crystal delta]

:c

ban me then 😭

[ocean robin]

NO

[fair iron]

I'll leave voluntarily if 🐱 may stay.

[crystal delta]

Holy shit no way

you stay Casca ❤

[valid ice]

no casca stays he knows some scots

[crystal delta]

yo Callum I wanna see some mspain skillz ❤

[ocean robin]

❤

[crystal delta]

not mspaint c:

[valid ice]

mspain? 🤔 what do you wish for me to engrave into myself?

[crystal delta]

make a tattoo in mspaint and do it?

[fair iron]

My neighbours were Scottisch when I lived in England, Callum! ^^

[ocean robin]

Now I must do errm who gave me algebra to do

Seriously doing algebra at midnight is great

[valid ice]

eh flappers get arrem to teach you calculus

it's fun

[ocean robin]

Calculus?

[valid ice]

🇭🇲 cattoo i'm planning on getting a few tattoos, but can't say they'll be designed in mspaint

[ocean robin]

wat is tis

[valid ice]

like calcul différential and intégral

[crystal delta]

meh^^

😮

Ja Ableitung und Integralrechnung! ❤

[opal sequoia]

Maths chat is ❤

[valid ice]

also base i think i decided on doing maths at uni

so you can love me again

but still not 100% sure

[opal sequoia]

Aww.

Do what you love.

[valid ice]

that's the issue 😛

i love both equally

[opal sequoia]

But if you don't love maths, we're done.

[ocean robin]

Yeah.

[opal sequoia]

Alle Leute müssen Mathematik studieren.

[crystal delta]

but who will take care of me when I'm in hospital?

[fair iron]

I would.

[opal sequoia]

The doctors who are also.mathematicians. 👌

[crystal delta]

lol 😹

[ocean robin]

uwu

[crystal delta]

most mathematicians I know would do more harm to me than good as a doctor :3

[ocean robin]

I will be a doctor so yah

[opal sequoia]

A maths doctor.

You can fix up the broken equations.

[sudden panther]

So. Flappy. Where's our solution?

[ocean robin]

wait

[sudden panther]

We can't wait much longer. 😦

What if there was a bomb and the only way to defuse it was to solve the equation written on it? 😦

[valid ice]

that's a really silly way to commit terror attacks

wolfram alpha exists

either way, it appears flappy has killed us D:

[fair iron]

She'll save us in time, have faith.

[pine ginkgo]

i think flappy died

[fair iron]

Have faith, Solet. ^^

[sudden panther]

Flappy. We all die at 1 am if you don't solve it by then. 😦

[fair iron]

I told you Flappy could do it!

[sudden panther]

Great job. But you used x for multiplication so the world blew up anyway.

[fair iron]

The English do that too.

[crystal delta]

LOL Arrem

[fair iron]

Last I checked, the smartest man alive was English. ^^

[ocean robin]

LOL

[sudden panther]

I think everyone does, but you shouldn't in this context.

And nah, I'm actually Austrian.

[fair iron]

😄

[ocean robin]

Goddamit, Arrem, I still use × in middle school.

[fair iron]

Anyway, before I end up staying longer than I intended. Great job once again, Flappy. Night everyone. ❤

[sudden panther]

Also to really nitpick, in x1 and x2 the 1 and 2 should be subscripts.

[ocean robin]

Good night Casca. Thankies.

[crystal delta]

❤ Casca ❤

[sudden panther]

You could always replace the x with a dot.

[ocean robin]

This was so fun!

[fair iron]

[sudden panther]

Do you Frenchlads use the dot? 🤔

[ocean robin]

Not yet.

Lemme check.

[sudden panther]

http://i.imgur.com/xwAkQ6T.png

That being 2 * 3.

[ocean robin]

Nah, it's * for us.

[sudden panther]

Of course @hot cloak's stupid exam would interpret that to be 2,3. 🤢

[ocean robin]

🤔

2,3 what

[sudden panther]

2.3

His exam writes the decimals like that. With a dot in the middle.

[ocean robin]

Oh yeah, you use dots. I use commas.

For decimals.

[sudden panther]

English uses dots haha. German uses commas as well. 😉

[opal sequoia]

We use dots for mulplication and decimals here.

But i don't think I've ever seen them confused. 🤔

[sudden panther]

Yeah, the exam Daniel linked put the decimal dot in the middle. Like in that image I posted above.

I'm not sure if that's convention or a typography fail though.

[opal sequoia]

Wow, that's weird then.

[sudden panther]

Also uh, did you ever go to sleep?

[opal sequoia]

I tried.

But no.

And I'm late for class. 😞

Because this train is so slow.

[sudden panther]

Bad Base, go get some sleep. BADDEST BASE, GO TO CLASS. OUTRUN THE TRAIN.

[tacit jay]

@sudden panther I've heard that decimal is written like that in some parts of the UK

Kind of outdated now, but still in use by some journals I think?

[hot cloak]

No, that's actually the standard in the UK/USA

[lavish saddle]

@tacit jay Imma move over here so it's not so in the way, but as Asylum, would he face any extreme difficulties? Would they help him get into college too?

He'd love to study afterall and if he can use the ''I'm an atheist'' to get out, then that'd be nice

[tacit jay]

Hm, good question, I'm not an expert in refugee law tbh, that was just an idea

If he gets accepted, he should be able to apply for college here in germany: https://www.studieren-in-deutschland.org/als-fluechtling-studieren/

Though depending on his education, he might first need to retake highschool or at least complete the highschool exams

[lavish saddle]

Yeah, I'm sure he'd have to do the Abi or so

[tacit jay]

Trying to find information if atheists from egypt qualify for refugee status here right now

[lavish saddle]

Thank you!! I appreciate it

[tacit jay]

If he's willing to, he could just try to get to germany and apply to refugee status and then see if it passes, but that of course carries the risk that he gets denied

[lavish saddle]

Yeah, I don't think he wants to go that risky 😦

His dad is just willing to pay the flight and nothing more

[tacit jay]

Well at least his family is helping him get out

What languages does he speak?

[lavish saddle]

Fluent English and Arabic

[tacit jay]

Hm, studying is no option then I guess, unless he already has a bachelors degree

[lavish saddle]

He does not

🤔 we will definitely look into the refugee thingy then

He seems interested in it

[tacit jay]

Hm

Is there actual political pressure against atheists in egypt?

[lavish saddle]

I think so

[tacit jay]

Also important if he decides to go the refugee route: He needs to enter europe in the country in which he wants to apply for refugee status

[lavish saddle]

They're really rude and all of his family is absolutely disgusted with him

Threats are real against atheists and everything...

[tacit jay]

Yeah, problem is that officially you only get refugee status if you are politically persecuted. Societal pressure does not necessarily qualify

[crystal delta]

ow man 😦 Good luck to him

religious pressure should work too right?

[tacit jay]

Still looking ...

Inofficially, there are people who get asylum who probably wouldn't qualify officially. There's been recent pressure to be stricter in that regard though, so who knows

[lavish saddle]

It should....I'm pretty sure it works for Austria and he might try for here since we're here and all

[tacit jay]

How old is he?

[lavish saddle]

22 or 23

I can't remember

[crystal delta]

Nur wenn eine Verfolgung aufgrund der persönlichen Merkmale erfolgt, die in der Flüchtlingsdefinition genannt sind, kann eine Anerkennung erfolgen. Zielgerichtet ist eine politische Verfolgung, wenn eine Person aufgrund ihrer Rasse, Religion, Nationalität, politischen Überzeugung oder der Zugehörigkeit zu einer bestimmten sozialen Gruppe verfolgt wird. Häufig wird die Anerkennung von Flüchtlingen abgelehnt, weil nach Auffassung des Bundesamtes eine Verfolgung zwar stattfand, aber nicht “zielgerichtet” war.

😐

dann ists eh schon vorbei

[lavish saddle]

Hm..

I mean...it's still ''worth a shot''...he's willing to try

[tacit jay]

Then the only other option is probably moving here for au-pair or apprenticeship, but again, I'm not sure hw qualifies

[lavish saddle]

ick, aupair x-x

[tacit jay]

@lavish saddle He need to pick the country where he wants to apply carefully, if he gets rejected he probably won't be able to apply in another country from what I've read

[lavish saddle]

😦 yikes

I really want to see him enjoy his life...

._.'' he asked me to take pictures of the outside once

of the outside since he has never seen grass before

[tacit jay]

For studying, that's a) probably too expensive, and b) requires good german knowledge and abitur-equivalent for a bachelor or good english knowledge and a bachelor for a master

[lavish saddle]

🤔 well that's crap

Once you get rejected once, you're completely rejected from all of them..

I mean, I understand it

but it still sucks x-x

He hasn't even started q-q

[tacit jay]

https://dejure.org/gesetze/AufenthG/17.html says he can apply for apperenticeship

[lavish saddle]

He had given up hope

[tacit jay]

But he needs to find a firm that will take him first

[lavish saddle]

Yeah, that'd be really hard to find

He has no german

[tacit jay]

and apprenticeship slots are already too few I think

yeah

[lavish saddle]

and germans would be taken over him in a heartbeat

[tacit jay]

Well, in that case I guess his best shot is really going through university

[lavish saddle]

He's willing to go anywhere

but he kinda wanted to be closer to us

[tacit jay]

Or French Foreign Legion

@cloud current Cool, what do you do?

[lavish saddle]

Yeah, that's true

I mean..Canada has them too

That's nice (:

[tacit jay]

ah, nice

[lavish saddle]

Maybe sweden?

I've looked a little and they have one of the highest acceptance rates for asylum

🤔 That seems terrifying

I can imagine that that's not fun...

Sigh 😦

Maybe in the future we can help him quite a bit more

but right now, we don't even have the apartment space to help him out q-q

I think it'd be much more managable if we could help him out

[tacit jay]

@lavish saddle Check this out, maybe: https://www.atheistalliance.org/activities/atheist-asylum.html

Try to contact them for help maybe

[lavish saddle]

😮 Thank you

[hot cloak]

What bank would you guys recommend I open?

I'll be landing in Frankfurt, but also would need something that would be available in Schmalkalden

I've been recommended DeutscheBank and Sparkassen

sparkassen***

why do you say that?

(i know nothing about them)

wow

that's deutschebank?

i've been recommended deutschebank because they're available in the US as well

not sure how that really helps me but

Sparkassen is what the school, (in schmalkalden), recommended me

because there's a sparkassen that's open there

but anything else you guys would recommend

🤔 ?

what does sparkasse kreis mean?

ah

so if i open a sparkasse in frankfurt, I may not be able to use that account in schmalkalden?

that's a problem...

[cold vessel]

I haven't been to my bank in ages. Is online banking not common in Germany?

[twilit garden]

you can get online banking as an extra

that's not how it works in my bank 👀

wow

thanks progress

i am at a volksbank and several friends of mine just have online banking on the side

idk, what criteria would be good tbh

i am there, i use it

it's harder to get a cash machine in Cologne with the Volksbank one

schebab

of course that exists

[fair iron]

Hast du das nicht mal verlinkt, Nemo?

[twilit garden]

nicht dass ich wüsste

[fair iron]

Ne, war doch Riot. 😄

Ich werde mir es egal wie oft sie es verlinkt anhören.

[twilit garden]

we look alike a lot

[fair iron]

^^

[twilit garden]

fuck i don't know about word placement in that one

we look a lot alike

no

[fair iron]

Beides geht.

[twilit garden]

hm

[fair iron]

Das Letztere ist aber besser.

[opal sequoia]

"We look alike a lot" sounds more like "We look alike often", that's all.

[fair iron]

^

[twilit garden]

huh, now that you say that

we same huga huga

[grave adder]

🤔

Potato.

Potato potato potato.

Potato.

What is potato?

It sounds like a bunch of meaningless connected syllables.

[arctic helm]

💩

[lunar urchin]

compared to what?

[arctic helm]

....

seems a bit out of nowhere

this convo

we did have a convo about open office

but that was yesterday

maybe it wasn't yesterday

but definitely not today

not here

[ocean robin]

Base, I need help for maths

Come here

[opal sequoia]

Hi!

What kind of maths is it?

[ocean robin]

[opal sequoia]

[ocean robin]

Wait, I'll show you the problem

[arctic helm]

[ocean robin]

So you must find the red part with knowing that half of the diameter of the circle is = 10m, and that all the circles don't have any space next to them

[thick charm]

Hey Flappy! Good luck

[ocean robin]

I alrready calculated the circle but no idea for that square thingy

Thankies Chuck! And hai!

[arctic helm]

radius is 10m

[ocean robin]

Yes

[arctic helm]

and you need to find the area in between the circles

no?

[ocean robin]

So I did 10^2 × pi

No

There aren't space between the circles

I just need to find the circle + the square thing

[arctic helm]

?

[ocean robin]

And nah, Professor Layton there.

[arctic helm]

what square thing?

the one in the middle, no?

[ocean robin]

Yeah.

[arctic helm]

which is in between the circles

that's what I meant

[ocean robin]

Yup.

Oh okay.

What if we consider this as a square? And we put the 4 circles in that square?

[opal sequoia]

Try to draw a square that uses the centre of each circle as the corners.

[pine ginkgo]

hehe

i remember this

[arctic helm]

ahhhh

yes

now I get it

[ocean robin]

Like that?

[arctic helm]

yeah, that's how you calculate it

yep

[ocean robin]

🤔

[opal sequoia]

Yeah, Flappy.

Now...

[arctic helm]

there are pizzas

err

[opal sequoia]

How much of each circle is in that square?

[arctic helm]

cones?

[pine ginkgo]

that form looks really suspicious 🤔

[ocean robin]

1/4?

[opal sequoia]

Yeah.

[ocean robin]

OH

[arctic helm]

which is practically one circle

[opal sequoia]

No, not practically. Exactly.

[ocean robin]

SO I NEED TO KNOW 1/4 OF THE AREA OF EACH CIRCLE

and then uh

[opal sequoia]

Well, 4 quarters = 1 whole circle.

And then you need the area of the big square.

[ocean robin]

🤔

oh yeah

The blank between the circles

[opal sequoia]

I mean, the square you drew. You need that area.

[ocean robin]

So wait that I see because I calculated that the area of a circle is 314m2

[arctic helm]

area of the square - area of one circle = area in the middle

[ocean robin]

So 314÷4?

[arctic helm]

no need to divide by four

you have the circle's area already

[ocean robin]

oh yeah true

[arctic helm]

now just the area of the square

of which one side is 2 x radius

[ocean robin]

And it's 20m right?

Oki dokie

So 20 × 20 = area of the square

[arctic helm]

then use my formula up there

need to use your imagination a bit to come up with the answer

[ocean robin]

Ok so area of square = 400m2

[arctic helm]

hence why base made the wonderful suggestion to use the middle of all circles

[ocean robin]

And area of circle = 314m2

[sudden panther]

Are we making flapper do math again?

[ocean robin]

Look, Arrem is here.

[arctic helm]

I was a bit thrown off because of the yellow lining though

[ocean robin]

We are resolving a puzzle of Professor Layton.

A big one.

[arctic helm]

made me thought that the circles weren't aligning correctly

[ocean robin]

They are though

[tacit jay]

Wait

Do the circles have a radius or a diameter of 10m?

[arctic helm]

radius

[ocean robin]

A radius yup

[arctic helm]

the line is difficult to see

[tacit jay]

ah ok

[arctic helm]

but it's until the middle

[ocean robin]

So how do we do now?

[arctic helm]

?

[ocean robin]

400 - 314?

[arctic helm]

just substract

yes

what else to do with it?

[opal sequoia]

Yep, good work.

The reason is... if you have a big space, and you know one portion of that space, then you can always calculate the remaining part by getting the "difference" between them.

[ocean robin]

Ok, it's correct wooo!

[opal sequoia]

Like... y = a + b since they have to add up altogether to the same amount.

[ocean robin]

🎉

[opal sequoia]

Good work though.

[ocean robin]

Thanks to you all too.

Now I can play to Professor Layton lol

[opal sequoia]

Enjoy.

[sudden panther]

Who the fok is that?

[arctic helm]

Is that the hot professor in Pokemon?

[opal sequoia]

Yes.

[arctic helm]

:ohmy:, Flappy

[ocean robin]

No, it's not that at all.

This is Professor Layton.

I know you know it.

[full falcon]

I found area of the middle square 85,84

am I wrong?

[opal sequoia]

How did you calculate it?

[fair iron]

Ooh, maths! What's the question? ^^

[opal sequoia]

Scroll up, Casca.

[full falcon]

I drew a square whose corners are the centers of each circle

[opal sequoia]

That's right though.

[full falcon]

Therefore side=20,area=400

[opal sequoia]

Although the question makes it easier because it includes the area of a circle.

[full falcon]

and in each corner there's a quarter of circle, so an area of a full circle is to be removed from it

400 - pi*10^2 = 85,84

[opal sequoia]

Yeah.

10^2

[full falcon]

oh yep

oops

[opal sequoia]

But yeah, it's roughly that.

[full falcon]

Good, I'm not that rusted^^

[opal sequoia]

It's fun too. 😄

[full falcon]

I actually enjoyed it :p

I'd play Prof Layton but don't wanna pay the console nor games... needa try to be a pirate

[hot cloak]

Only knew the one till level 2...

[cold vessel]

Whoah, Galton boards are awesome

[full falcon]

good luck with the n rows 😂

[valid ice]

hehe, haven't seen galton boards before

[hot cloak]

That meme is so good

Dank af

[opal sequoia]

😄

The galton board thing made me laugh.

[crystal delta]

@ocean robin

[crystal delta]

do et 😛

[fair iron]

^

We believe in you. ❤

[sudden panther]

^

Can confirm. Source: We discussed it and came to the conclusion that we believe in you.

[fair iron]

And that (w + 4)^2 = 900 is easier to solve than P vs NP. :/

[sudden panther]

We start with the easy stuff Casca.

[fair iron]

^^

[full falcon]

Got it

8D

goes back to piano

[fair iron]

Please be sure to use [#Spoiler](Answer here). | Edit: Arrem made me tell you that this doesn't (yet) work.

[sudden panther]

Casca pls. 😛

[fair iron]

Sorry. 😃

[full falcon]

Ok I don't brag around then ;;

[ocean robin]

Yes. Math.

[fair iron]

Have you solved it yet, Flappy? 😃

[ocean robin]

No, I just finished eating lol

Gonna do it now

And w us like x or is it a set number?

[fair iron]

Like x.

Use whichever letter you wish.

[ocean robin]

Oki dokie.

[fair iron]

Huh?

[ocean robin]

How do I do next?

[full falcon]

That's one way to go

[sudden panther]

That's one way to do it.

3 fast 5 me 😦

[full falcon]

:P

[fair iron]

You're not wrong.

[ocean robin]

but how do I know x now

[sudden panther]

You use the fancy formula that Cassie taught youlast night.:P

[ocean robin]

OH

OH YES

[full falcon]

Then I'm afraid you can't continue if you didn't learn delta

[fair iron]

You don't even have to use that.

[sudden panther]

There's a simpler way, but we can discuss that one later. 😂

[ocean robin]

Arrem.

[fair iron]

Too slow again. ^^

[ocean robin]

If there is a simpler way

[full falcon]

You'll look for it afterwards!

[sudden panther]

|latex x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

[ocean robin]

then I do my way then

Thanks btw

[crystal delta]

Arrem was faster :3

[ocean robin]

That's what I needed

[crystal delta]

do you know what a b and c are?

then it's simple c:

[ocean robin]

b = 8 c = 884

a = 1

[crystal delta]

sweet

[full falcon]

careful

with c

[ocean robin]

🤔

[crystal delta]

well

you need = 0

[sudden panther]

More precisely, careful with which side the c is on.

[crystal delta]

so it's negativ

[fair iron]

^

[crystal delta]

😛

[full falcon]

You need to present it on the form ax²+bx+c = 0 so c changes sign

Too slow this time

[sudden panther]

2017
writing formulas by hand

[sudden panther]

mmmmmmm

[fair iron]

👌

[ocean robin]

uh oh

[full falcon]

told you I haven't learnt latex yet :(

[sudden panther]

Haha, fiine.

[crystal delta]

this one is easy to write though 😄

[sudden panther]

Do you get the reasoning behind that, Flipperflopper?

[full falcon]

Well there's no special sign at all needed is there?

[ocean robin]

And this is exactly like the previous formula?

[fair iron]

Yes.

[crystal delta]

just ^ + =

[fair iron]

^

[full falcon]

oh yep

[ocean robin]

what is x here?

Oh silly me

OH I SEE

SO 1X^2 OKAY

[crystal delta]

yep

[ocean robin]

bx

[sudden panther]

|latex &\textcolor{red}{a}x^2+&\textcolor{green}{b}x+&\textcolor{blue}{c}&=0\
&\textcolor{red}{1}x^2+&\textcolor{8}{b}x+&\textcolor{blue}{(-884)}&=0

[brave steeple]

Rendering Latex failed. See help if you think this is a mistake.

[ocean robin]

OH 8X

[sudden panther]

fok

[ocean robin]

AND C IS 884

[full falcon]

much enthusiasm :p

-884

[ocean robin]

wait

THIS IS EXACTLY THE ALGEBRA YOU GAVE

WHY IS IT A FORMULA

OH

[ocean robin]

AND IT GIVES 0

[sudden panther]

There we go.

[ocean robin]

AAAAH

[full falcon]

much dedication

[ocean robin]

i don't like those kind of algebra lol

[full falcon]

Sounds doable, I'm gonna have fun learning some LaTeX next week

[ocean robin]

And ax^2 + bx + c = always 0?

[full falcon]

yeah you need to put everything on one side

[ocean robin]

okay i must note this in my head

[full falcon]

But it's just to determine what a,b,c are ^^

[ocean robin]

easy that

[full falcon]

Then you can directly apply the former formula

(Tu réalises qu'on apprend ça en 1ère S? ^^)

[ocean robin]

Another algebra Arrem plzz

WHAT

[sudden panther]

What?

[ocean robin]

EN 1ERE S

[full falcon]

xD

[ocean robin]

WHAT

[sudden panther]

LESS FRENCH MORE MATH THANKS

[hot cloak]

This should be renamed to #math

[ocean robin]

OK ARREM

[crystal delta]

is it your turn then @fair iron ? 😄

[ocean robin]

BUT EXCUSE ME I LEARNT THAT WE LEARN THIS AT 11TH GRADE

WHAT

[full falcon]

Ok, maybe ES as well but I'm not sure

[ocean robin]

Still

WHAT

[full falcon]

They're noobs, maybe they do it in 12th

[sudden panther]

WHAT GRADE ARE YOU IN NOW YOU MEME

[full falcon]

🤣

[crystal delta]

^^

[ocean robin]

I DON'T KNOW ARREM

[sudden panther]

HOW CAN YOU NOT KNOW?

[ocean robin]

wait

i must search

[fair iron]

I guess it is, 🐱!

[full falcon]

I don't know the corresponding between french and american years

[sudden panther]

How can you not know your own grade? 🤔

[ocean robin]

ok can I say I am 3e then lol

Are you satisfied?

[fair iron]

Flappy:

2. x! is the number of seconds in 6 weeks.

[sudden panther]

Casca.

[fair iron]

Arrem.

[crystal delta]

xD

[sudden panther]

We didn't get an answer to the last thing yet. 😛

[fair iron]

In that case, what were you trying to say, 🐱? ^^

[full falcon]

apparently 3° is 9th grade

in the us

[ocean robin]

^

[crystal delta]

lol I thought she needed another one already 😓 but keep it in mind Flappy 😄

[ocean robin]

I am 9th grade.

[sudden panther]

So, back to math.

[crystal delta]

^

[fair iron]

Agreed.

[ocean robin]

it's coming boi

[ocean robin]

LOO

[fair iron]

Get ready, Arrem and 🐱!

Flappy says the answer's coming. ^^

[crystal delta]

🥁

[sudden panther]

Where did she say she was ready? 🤔

Silly Casca. 😛

[ocean robin]

brah

wait

little mistake

forgot the - at 884

shiet

[fair iron]

💯

Correct. 😃

[full falcon]

Good job^^

[ocean robin]

oh yay

[sudden panther]

Also pls switch to dot for multiplication. 😛

[fair iron]

^

[ocean robin]

NO

WELL I TRY

[sudden panther]

Using x is how you make miskates.

[ocean robin]

BUT YOU SEE HOW I WRITE X AND ×

[crystal delta]

as soon as you start working with x everywhere, you will understand

[ocean robin]

AH

[full falcon]

miskates?

[ocean robin]

[sudden panther]

mikstaes*

[ocean robin]

LOL

Anyway Casca

You gave me something

[fair iron]

Yep. ^^

[ocean robin]

Don't say I am doing 11th math work

[sudden panther]

So. Want a hint how to do it in a simpler way? 😛

[full falcon]

So that was the long way to do it :p

[ocean robin]

NO I HAVEN'T READ IT YET

So x! = 6 weeks?

[fair iron]

Arrem means the previous question, Flappy.

[sudden panther]

x! seconds = 6 weeks

[fair iron]

^

[full falcon]

Oh that sounds interesting

[ocean robin]

So I know that for example 7! = 7 x 6 x 5 x 4 [...] x 1.

[fair iron]

Yep.

[sudden panther]

Correcto.

Except dot. 😛

[ocean robin]

but whaaaa never did a problem like that

ARREM

[sudden panther]

kek, some spacing wouldn't have been bad

[fair iron]

😄

[ocean robin]

I don't want to do like "ok so one week is [...] seconds so we just do x6"

[minor heart]

Woah

[fair iron]

It just looks like you're multiplying a lot.

[sudden panther]

Also, there's no "real" way to solve a problem like that.

Apart from just converting 6 weeks to seconds and seeing what number could fit.

[ocean robin]

Roots can't work there

wat can I use

[sudden panther]

Hm.

Here's an idea.

Start writing it out.

[ocean robin]

1 hour is 3600 secs right?

[sudden panther]

If I wanted to convert a year to seconds, I'd start by writing
1 (year) * 365 (days/year) * 24 (hours/day) and so on. Can you do the same for 6 weeks?

And yes, but don't take that shortcut. 😛

[full falcon]

:^)

nvm can't read

[fair iron]

Working with the solar day I see, Arrem.

Sidereal > Solar.

Not that a sidereal day helps here at all.

:(

[sudden panther]

365.25

happy? 😛

[full falcon]

xD

[fair iron]

*365.24, actually.

:]

The .24 is why we have a leap year on every new century divisible by 400, or every non-century divisible by 4. ^^

[sudden panther]

Huh, that's pretty cool.

So quick update: Depending on how you view things, converting 1h to 3600secs might work even better. 👌

[fair iron]

^

[sudden panther]

If she's even alive. 🤔

[ocean robin]

i am coming boi

[sudden panther]

So. Try doing what I said above, but you can 'cheat' a bit by converting hours to seconds directly.

Now how do you know that 3628800 is 10!? 😄

[ocean robin]

well

I tried 9! and it was almost that

So tried 10!

[sudden panther]

Well, let's expand the terms to see how you could do it without plugging in random numbers. 😄

[ocean robin]

.w.

[fair iron]

For starters, we have 6 and 7.

6 weeks, and 7 days in a week.

[full falcon]

solve('factorial(x) = 6724*3600',x)

muahahah

[fair iron]

So: 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10.

8 numbers left to cover.

[ocean robin]

okay.

so then, 1 day right?

Wait Casca, you putted 5 twice

[fair iron]

We can get rid of three more numbers as follows:

Oops, thanks. Fixed it. ^^

There are 60 minutes in 1 hour.

60 = 2 * 3 * 10.

(You could also do this with seconds in a minute)

[ocean robin]

[fair iron]

Currently: 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10.

[ocean robin]

60 mins...

[ocean robin]

WHAT

[fair iron]

That's easier to read.

[ocean robin]

oh gotta go for 20/30 mins guys

[fair iron]

The underlined numbers have already been used.

[ocean robin]

[fair iron]

😮

Take care!

[crystal delta]

Lator Fläppers

[sudden panther]

I love >latex

[fair iron]

I've sent her the Numberphile video on 10!, that should explain the rest. ^^

[crystal delta]

well if it would work...

[sudden panther]

We should have added it ages ago.

[crystal delta]

yesh^^

[sudden panther]

Also im pretty sure botto just has to install latex on his server and it'll work

[ocean robin]

I am back

[sudden panther]

So, is the bot's explanation clear? 😛

[ocean robin]

Oh, yes. Thanks Arrem.

[sudden panther]

Goodies. Now, wanna solve that equation we had earlier in a much simpler way? 😛

[ocean robin]

Oh ye.

[sudden panther]

Righto. So we started off with

[sudden panther]

What happens if you take the square root of both sides?

[ocean robin]

If I take it?

[fair iron]

Yay, you're back! 🎉

[ocean robin]

[fair iron]

Too slow, Arrem.

I explained that half an hour ago, sorry. ^^

[sudden panther]

Too slow? 🤔

[fair iron]

She already knows.

[sudden panther]

Oh. Why didn't you say so, silly Flapper. 😛

[ocean robin]

brah brah

[sudden panther]

Also yes, you take a square root.

[ocean robin]

Take = delete it?

[sudden panther]

Nah. Taking the square root of x is

[ocean robin]

OH YES SILLY ME

[fair iron]

Very silly. ^^

[ocean robin]

😅

[sudden panther]

Mmm. It's gonna take me at least a week to get bored of >latex. ❤

[ocean robin]

👀

WHAT THE HECK IS THAT

[fair iron]

A triple integral and some other fun stuff.

[ocean robin]

oh there is the area of a sphere in this

[fair iron]

The volume of a sphere is at the end.

[ocean robin]

Volume, mistake.

[fair iron]

Ah, you were faster.

^^

[ocean robin]

I said area though. ^^

[fair iron]

True. ^^

[ocean robin]

How can you know the area of a sphere though? If so, it's the area of a circle right?

[fair iron]

Yes.

You could work out the surface area of a sphere, though.

Which is 4πr2.

[ocean robin]

I did not know that.

Now I thought 🐱 wanted to make me resolving algebra. Oh well. I love those math evenings.

[sudden panther]

That lovely triple integral is how you get the formula for the volume of the sphere. 😅

[ocean robin]

👀

WHAT

THAT LONG

[fair iron]

"That long" is subjective.

[sudden panther]

^

[fair iron]

Some things are worse.

Actually, lots of things are worse.

[sudden panther]

^

[cold vessel]

The greeks managed without triple integrals. Checkmate, Newton

[ocean robin]

Well, that long, for me Casca

[sudden panther]

Especially since that's just expression = result.

Actually solving it step by step would be even longer. 😛

[ocean robin]

You can't see formulas like that in 9th grade

so yes long lol

And maybe because there is signs I don't know yet too

[sudden panther]

Integration is just summing up a bunch of tiny rectangles. In most cases.

[fair iron]

Or the volume of a shape when rotated around an axis.

But that's not important right now.

[ocean robin]

An axis?

[fair iron]

Axes.

[ocean robin]

Oooooh.

[uncut copper]

maann

[ocean robin]

So I know thosw already noice

[uncut copper]

yeah i have to refresh my memory

[ocean robin]

I am now thinking why I have only 15 in maths...

🤔

[fair iron]

In Germany, 15 points is the highest grade achieveable. ^^

[ocean robin]

In France, it's 20.

15 out of 20.

[fair iron]

75% is still great.

[ocean robin]

Yeah, I think so, I made huge progress all this year.

[cold vessel]

Wow, that's a lot more possible grades than we have

We have 1-6 in HS and A-F in uni

[sudden panther]

What are you doing in school?

[ocean robin]

Began at 12, finishes at 15,5.

Well uh

powers are still triggering me

[sudden panther]

Quick what's

[sudden panther]

No, not you, people who aren't in highschool.

[cold vessel]

Arrow notation, please

[ocean robin]

NO WHAT

ARREM WHAT

(2 × 2) × 2 × 2?

🤔

[fair iron]

Arrow notation is a little advanced, I think. Let's not combine too much at once.

You start at the very top, Flappy.

2 * 2 = 4.

Then you still have 2^4 left.

[sudden panther]

op delivers

[ocean robin]

🤔

[fair iron]

Two arrows? Arrem, what.

[ocean robin]

What is that arrow first?

[cold vessel]

@fair iron Looks correct to me?

[sudden panther]

Yes. Double arrows represent repeated exponentiation.

[fair iron]

^

[ocean robin]

Expowhat

[sudden panther]

Except the padding looks weird. I hate that. 😦

[fair iron]

Padding looks fine. ❤

An exponent is a power, Flappy.

In 2^3, the exponent is 3.

[ocean robin]

exponentiation what is this

oh okay

[sudden panther]

Nah, there's a tiny bit more spacing after the 2 than before the 3. 😅

[ocean robin]

I just do not know the English names for those then

[fair iron]

Wouldn't 2^2^2 actually be:

[fair iron]

I'm tired. 😄

Sorry, carry on as you were. ^^

[ocean robin]

🤔

[cold vessel]

Single arrow is just exponentation

[sudden panther]

So. Flipperflopper.

[sudden panther]

GG I added a question mark. Ignore that.

[ocean robin]

LOL

[sudden panther]

(Don't ignore the whole question, though, just the question mark. :P)

[ocean robin]

Oki dokie.

[simple vortex]

There is not only 8

There's a few hundred

there's kinda three types:
ones that end in -e but are masculine (like the ones you listed)
ones that have latin/greek endings (der Elefant -> den Elefanten)
other ones that are mostly people or titles (der Mensch -> den Menschen)

[lilac dew]

there's also das Herz

which is just weird

[opal sequoia]

It's just listing examples.

[gilded kraken]

Pretty sure der Herr is irregular too, so I wouldn't say that that's an exhaustive list, Eine.

[opal sequoia]

It might only be 8 if you're talking about those specific set of endings, I'm not sure.

But don't be surprised if you come across more.

[gilded kraken]

Ah, ok

[opal sequoia]

No, der Herr does have an irregular form.

It just doesn't take the genitive -ns ending.

[opal sequoia]

What do you mean by wrong?

Well, they're all weak masculine nouns (except for das Herz, of course), but der Herr has a different form in singular vs plural, which makes it a unique exception.

[opal sequoia]

That's good.

[grave adder]

@sudden panther No fair, where are my math questions? >:C

[opal sequoia]

In your exam!

[grave adder]

Finished today, 2 hours ago!

I want MOAR.

[opal sequoia]

Hehe. 😄

[sudden panther]

Base can give you one.

[opal sequoia]

Oh, sure.

Hmmmm.

I don't know what level of maths you're at.

But if you tell me, I'll give you a challenge.

[sudden panther]

Oooh. A challenge! Sounds challenging.

[grave adder]

Do it! >:D

Challenges rarely sound challenging.

And the level I'm at...

Well, I know basic trigonometry, I guess? Simultaneous equations? Dividing algebra mathy equations with algebra mathy equations? And how to add 9 and 10 together?

...okay, I'll admit. I don't know much. What the heck is an exponential.

[pine ginkgo]

nice

time to do some rotations in n-dimensional space

[grave adder]

Nonononono

That sounds scary

[opal sequoia]

Ohh, cool. So no integration then?

[grave adder]

Nope D:

Oh, wait. Is exponential a fancy name for "the nth power of something"?

[opal sequoia]

Yeah.

So let's just go with... y = x^3 - 5x^2 + x + 10

What are the coordinates for all the axis intercepts?

[sudden panther]

BASE

2017

[opal sequoia]

Oh, actually, for people who are into maths, maths club at uni likes to put out weekly puzzles for people, so if you're interested here's the one from last week: A perfect number is a number that is equal to the sum of its divisors excluding itself. If p is an integer such that (2^p) - 1 is prime, prove that (2^(p-1)) * ((2^p) - 1) is a perfect number.

[opal sequoia]

Ty Arrem.

2017, I don't have to write the latex myself; Arrem will do it for me.

[sudden panther]

And he'll mess it up.

[opal sequoia]

Uh oh.

[opal sequoia]

@grave adder ^^^^

[thick charm]

🤔

Guys I think you broke the internet

[grave adder]

O-okay, that looks scary (the second math problem)...

And as for the first..

I... actually don't know how to solve that...

[sudden panther]

Replace the y with 0 and the internet should be back to its normal state.

[opal sequoia]

Well, do you know how to find an axis intercept in general, Sas?

Like let's say... y = 2x + 3

Where does it cross x and y?

[grave adder]

Wait, lemme try that.

[sudden panther]

Or 2x-4 if you want prettier numbers. 😛

[opal sequoia]

True.

[grave adder]

Yes please

[sudden panther]

By which I mean not fractions. They're not that bad.

[grave adder]

But I hate fractions D:

[sudden panther]

Good. Then do the one Base posted. 😈

[opal sequoia]

Do both. 😄

[sudden panther]

Oooh, even better.

[thick charm]

I think I get the concept

[grave adder]

Well, for the first one, I've only learned to solve problems like ax^3 + bx^2 + cx + d = 0, but since it's y in this case...

And nope (to the axis intercept thingy), I'm ashamed to say that I've forgotten a lot about how graphs work

[sudden panther]

Well then this is a perfect time to cover the intuition behind what the solution to those problems represents, so that you can apply it in the wild and not just in "controlled" environments. 😄

[pine ginkgo]

nice thing about fractions is

you can just ignore them being fractions

[opal sequoia]

That's okay. It's fine to not know something. It's sort of like when you learn German. You might forget like 50 times how to write an adjective, but you practice until you remember.

[grave adder]

But being bad at maths is being bad at a lot of stuff D:
And then again, I can't Deutsch 😭

So, what would be the answers? And why?

[sudden panther]

2 and -4 because math said so

[opal sequoia]

Okay, so... when you find an intercept, you're basically finding when either x = 0 or y = 0.

Because if you look at a graph, you cross the lines at those points.

You cross the x axis when y = 0. If you draw the y = 0 line, it's literally the x axis.

[thick charm]

Hey I did it

[opal sequoia]

Oh?

[thick charm]

I think

maybe

I found the y intercept in that long one

It really is just 2?

[opal sequoia]

That's one of the intecepts, yes.

[thick charm]

then the other one

[opal sequoia]

x intercept, though.

[thick charm]

should be uh

[grave adder]

So, an intercept is where the line crosses the x axis or the y axis?

[opal sequoia]

Yeah, Sas.

[thick charm]

It's a low number

I can tell that much

[opal sequoia]

The long equation I gave has 3 x-intercepts and 1 y-intercept.

[vale magnet]

Ive shared a book to you guys. Its in resources channel

[opal sequoia]

The short one has one of each.

[grave adder]

Okay...

[opal sequoia]

So the way you solve it is to basically say... what does y = ? when x = 0? And vice versa.

[grave adder]

Ohh

Also, is the gradient of the line defined by the 2 infront of x in the shorter equation? Might not be related to this, but I think I remember learning these things once

[opal sequoia]

Yep, that's right.

[grave adder]

Oh wait, I remember

So, just substitute x with 0 since that's where it'll intercept? And then solve?

[opal sequoia]

Yep.

That's for the y intercept.

[pine ginkgo]

the x-intercept is kinda a joke questions ehehe

[grave adder]

So, for y = 2x + 3, it's (x, y) = (0, 3)?

[pine ginkgo]

wait, 0?

[grave adder]

The coordinates on the graph? Or did I mess up again?

[pine ginkgo]

btw

you should label your solutions properly

[opal sequoia]

Yes, that's right, Sas. But what about the other intercept now?

[grave adder]

(x, y) = (-3/2, 0)?

[opal sequoia]

Yep, perfect.

Fraction is better than decimal!

[pine ginkgo]

you don't really have to write is as coordinates tho

[grave adder]

Not agreed >:C

[pine ginkgo]

it is

decimals are slow

and stupid to work with

since it's harder to calculate with

[opal sequoia]

There's just too many situations where you can't actually write something as a decimal.

[pine ginkgo]

for example it's way easier to take the root or exponent of a fraction than of a decimal

[grave adder]

Fine ;;

Well, that's true...

[opal sequoia]

It's fine for this kind of thing though. It wouldn't be wrong.

But it won't be an effective format for you for much longer in your maths education.

[grave adder]

:c

[pine ginkgo]

well

[grave adder]

Well anyways, thanks!

[pine ginkgo]

in the long run

[sudden panther]

Yeah, at one point you have to make the switch to IEEE 754 floats.

[pine ginkgo]

you kinda stop thinking about them as numbers anyway

[grave adder]

Internet Extreme Elite Explorer v754?

[pine ginkgo]

it does not really matter if it's 1.5, 5/21, or 235362626

[grave adder]

Why, though, Solet?

[pine ginkgo]

well if you know how it works

you just have to input the numbers

and it's mostly the same all the time

if a formula tells you to multiply it by 5

it doesn't matter what the base value is

it will be than just base value multiplied by 5

and in the end

you can just substitute numbers or terms with variables

:P

it's more important to think in concepts

than in numbers

[opal sequoia]

Yeah, true.

[pine ginkgo]

while some decimals can look nicer

it doesn't matter if you never look at them anyway

:P

[opal sequoia]

The main reason why, at this level, fractions are better is because... decimals are an extra step that you don't need.

Totally not worth the time.

[pine ginkgo]

you can also look at it like this

don't look at 1/2 as a fraction

or 0.5

look at it as 1 divided by 2

that helped me in the begininng, when i needed to calculate more with fractions

and also liked pretty decimals

[opal sequoia]

I guess you're right actually, Luna. I never really thought about it, but I don't even see them as one number. It's just top number on bottom number.

[pine ginkgo]

yeah nowadays

but back then :D

it also helps when you are programming

since you also stop thinking about numbers

and just have inputs and outputs

(as an example)

when you make a little fancy function

it doesn't really matter what kind of integer you input

as long as it's an integer

(and you have done it well)

you look at the number though

if it errors

:(

[sudden panther]

addOne(2_147_483_647);

[grave adder]

Ahkay, thanks!

[opal sequoia]

Btw if anyone else wants to solve that first question, feel free. Aside from nerds who already know how to do it easily.

[grave adder]

"A perfect number is a number that is equal to the sum of its divisors excluding itself."
Example?

[opal sequoia]

Not that, the other intercepts one.

[grave adder]

Oh, okay

[opal sequoia]

But that, hmm... let me think of an example...

[sudden panther]

https://en.wikipedia.org/wiki/List_of_perfect_numbers

[opal sequoia]

So, let's say the number 28. All the possible factors are: 1, 28, 2, 14, 4, 7.

Leave out the 28.

1 + 2 + 4 + 7 + 14 = 28.

[grave adder]

So, a number that equals to the sum of its factors excluding itself?

[opal sequoia]

Yep.

[grave adder]

Wait, I just repeated the question...

[opal sequoia]

Hehe.

And if you can prove that, please feel free.

[grave adder]

Unfortunately, I do not feel free 😦

So, I think I got one intercept

x = 2?

[opal sequoia]

How did you find it?

[grave adder]

Well, substituting y as 0, I got 0 = x^3 - 5x^2 + x +10

Factorised it into (x-2)(x^2 - 3x - 5) = 0

[pine ginkgo]

uhm

[opal sequoia]

Good.

[sudden panther]

2 0 1 7

[grave adder]

And took (x-2) as 0 ?

Arrim pls

[pine ginkgo]

ehehe

[opal sequoia]

Yep, that's the right way to do it. There are 2 more intercepts though.

2 more x intercepts, I mean.

[grave adder]

Quadratic equations ;;
