@Arjun good book title 🤔

@CharlieShuffler here are two functions like max(x,0) following the description I gave you desmos.com/calculator/ehg9gfekvs

piecewise polynomial also does the job desmos.com/calculator/ihnnpxgr81

@CaptainBohemian get a lizard,frog,spiders...etc they are natural predators of ant

lord @CalvinKhor aka lord confused didn't u sleep?

i did, but you dont sleep forever lol im awake now

@CalvinKhor Are you working on your office works?

yes

u sleep less than 7 hr?

i was not awake 7 hours ago

i slept probably 12 hours ago i think

i was awake for a few but not here

I slept for 11 hr

first time sleeping

that much

@CalvinKhor When you get your off day? Is it on sundays?

my off day is whenever i dont feel like working lol

Lol

could be every day but then papers dont write themselves, do they...

What’s the official off day?

Do they make your work whole week?

i guess officially mon to fri workdays

no, they dont

I make me work the whole week

today no procrastinating so I wouldn't be active in the chat

Okay!

@NoseBleed glhf!

@CalvinKhor see ya soon

Can you just tell me how to make that triangle roll? (I know you’re already busy with office works, so I won’t disturb you much)

well the starting point IMO should be $$\cos\left(t\right)\left(x-t\right)+\sin\left(t\right)y<0$$ where $t$ varies

or something like that, i didnt check if it made any sense geometrically, i just dumped it into desmos and it seemed to do approximately the right thing...

Okay! I shall not disturb you today about that. I will work on it and let you know about it tomorrow.

haha

ok actually it does make sense

so its like this

geometrically the equation $ax+by≤0$ should probably be seen as $\binom{a}{b} \cdot \binom{x}{y} \le 0$

so if you were to draw axis lines in direction (a,b), this says (x,y) is in the negative half

i.e. if you use $u=\binom{a}{b}$ and $v=\binom{-b}{a}$ as your orthogonal coordinate system and $\binom{x}{y} = a u + b v$ this is just $a\le 0$

@CalvinKhor Why I’m getting a different answer here than others? math.stackexchange.com/a/3763986/569595

and using $(\cos(t), \sin(t))$ chooses $u$ among points in a circle

Okay

not sure

ill think a little

its the last step

$2(\cos^2 x + 1) ≠ 4 \cos^2 (x/2)$

the LHS is always ≥2 but the RHS can be 0

eg when $x/2 = \pi/2$

i see that an4s has seen the same thing as me

and also mark viola now lol

Lol

i dont think i would ever write this lol

its even in a published paper (sciencedirect.com/science/article/pii/S0263224114003893) i.e. not a prank

@CalvinKhor ,can you share the paper link?

Oh ok

U have shared

better screenshot to prove its real

dont think i can share the paper itself, its not free access

I'm more interested in graduate studies than high school studies.

Why do the services of engineers and physiologists cost money but the the enlightenments of scientists don't?

are you claiming scientists don't get funding?

No, I mean scientists can't make money by enlighting others, like publishing, giving talk in conferences, workshops, seminars but engineers can make money by doing engineering services for their customers and physiologists can make money by providing health care.

hmm. what services are you providing though. teaching more useful things is already not paying great

I think I don't like to do services to others very much.

@Knight you were so close

well thats kind of it then isn't it

I don't like the teaching I have ever been given.

So I quit it, and applied for research assistant position.

@Arjun whats the reason?

scholarship

@user69608 ,it was a joke ;-)

@Arjun but the thing is how you increased?

@user69608 , mazik

Lol

@Arjun just saying

@user69608 ,use english or someone will flag you ;)

food services are the most urgent

that's why convenience stores which open 24 hours have food all times though their food is not necessarily delicious.

last wee hours I ate their rice lump and rice roll. But I am hungry again now.

it's very absurd those money raisers for hungry children stress those children needing help don't have three daily meals and some of them only have only a meal a day. They speak like we all have daily three meals.

It's really not easy to have daily three meals if there is no automatic meal service.

we are far busier than those hungry children.

if those money raisers have time to raise money on the street, it's better they volunteer to work on food for us.

I think that the services like Zomato and Swiggy are working perfect!

what is Zomato and Swiggy?

@CalvinKhor I haven't checked if Word can be worked on phone. Actually I feel reading on phone incurs eyestrain easily.

how do you stave off so frequently-occurring hunger?

I am being defeated by it.

how do you high schoolers fund your studies?

i think you should use the app if you really need to @CaptainBohemian

@CaptainBohemian it's an app you can download on your mobile phone. They essentially deliver food you order from a restaurant to your doorstep

money is so useful in helping with materials

if a person says how nice he has treated you without providing you substantial money nor doing labor service for you, he is a hypocrite.

because persistent food supply requires substantial money.

persistent food supply is the mainstay for any work.

@sai-kartik I guess I don't have budget for UberEats. It would be nice if I can find a studio in downtown area, but a public studio isn't convenient for me.

or it's better the studio provides public computers for free use.

I am set to finish 4 week course in 1 week

got tired and came here

(removed)

(removed)

and how are u guys doing?

I am hungry.

I caught up courses of more than four weeks in one to two weeks last month.

It was so tiring.

I feel the most substantial help I can get when I am busy is serving a meal to me every 6 hours.

I eat once a day

getting meal every 6 hr even when sleeping lol

only in holiday I eat twice a day

@NoseBleed , well humans eat thrice a day ;-)

what do you eat tho?

chicken?

sandwich or burger most of the time... it is very inconvenient for me to eat non exaggerated food in my country or those healthy for istook far from my location

@Arjun what do indian people eat?

most of the time

curry

roti

chawal

daal

sabji

in english, bread, rice, pulses, vegetables

etc

@NoseBleed , where do u live?

@Arjun that's a secret :P

I and knight had a deal

with my location on earth

@Arjun sounds healthy

@NoseBleed , i know, where u live ;)

@Arjun pretty sure u can't guess 😈 extremely hard

@NoseBleed , i don't guess

i know

@Arjun might me wrong 🤣

@NoseBleed ,i have said it onnce and i'll say it again I KNOW

I am going for a hike

take care :)

@NoseBleed ;)

good

@CalvinKhor Cool very nice. Thanks alot

@NoseBleed do you hike back now?

Are you happy?

@CaptainBohemian well I am top of the mountain

@CaptainBohemian yeah

you should go to hike sometimes

finding comet neowise location right now

the trajectory

I hike every day since I inhabit on a hill.

it's too cloudy unfortunately

@CaptainBohemian nice

@CaptainBohemian r u able to see neowise

comet?

But it's so tiring to hike under sunny days

@CaptainBohemian yeah gets sweaty

I don't know where to see Neowise

now I am very sweaty

@CaptainBohemian depends on ur location

nasa has info

I am going to look up where to see Neowise.

nasa.gov/feature/how-to-see-comet-neowise

may be it will help

Take compass or phone with u

@CharlieShuffler you're welcome. One feature of my functions is that for $x$ large enough, they are exactly equal to $\max(0,x)$, but the cost of this is that the functions cannot be analytic (while $\log(1+\exp x)$ is analytic). it is possible to make a $C^\infty$ function but graphing it in desmos is a little annoying (you can check the "smooth compactly supported function" page on wikipedia for some information)

$${\Huge Paramanand ~Singh ~you’re ~Welcome ~here}$$

If you happen to visit here,, please ping me. I have to talk to you.

@Knight , are you aware that this did not ping him?

@Arjun Yes of course

janta aate hue

I feel too full now

@Arjun Please don’t talk to me in Hindi

@Knight , i wasn't talking to you

If you won’t change your behaviour I shall have to contact mods.

Ugh

Can we please stay on topic guys?

yep

We are

@Knight , well, what did i do this time bro?

No I mean you were gonna call the mods again

all i said is people are coming here

If the mods are repeatedly called, this room might be deleted. Let's not have that happening

My sentiment has been disturbed once more, I’m going to cool down, but please try to friendly to each other folks

@Knight , i don't understand

how?

when/

who was'nt friendly

@Knight @Arjun has a point. What happened this time?

Can I ask for the meaning of "janta aate hue"?

@CalvinKhor , i gave above

people are coming to this room

@Arjun this one?

@CalvinKhor ,yes

google translate gives "Coming public" which doesnt make sense

@CalvinKhor it basically means people are coming

I can confirm that

With total honesty

no, i trusted arjun lol i just didnt understand

@CalvinKhor ,lacks contex here

@CalvinKhor ,janta idhar aate hue

try this

better context

thats "The public coming here"

works better yeah

@CalvinKhor , because sai and cap and one other joined almost at the same time

leave this

sup guys?

nm, wbu?

@CalvinKhor , boring as hell, today i found myself reading gulliver's travells

can you imagine that!

what is gulliver's travels lol

I'll just say this, for the main chat there is this math.meta.stackexchange.com/questions/3890/… which doesn't say that it has to be english. I don't think chat needs to be in english and I'm not convinced people flag (just) because its not in english. If we want to enforce some rules here, I think we should be clear and transparent about it (the room description should have some space)

How bout a rule like talking in other languages allowed as long as you provide a translation?

@CalvinKhor , yes since the owner is also indian

@sai-kartik , hmm

or

This would ensure proper translations and not non-trustworthy Google ones

use it only if there are there are only more than 2 users

Some people never go crazy. What truly horrible lives they must lead

Also this would minimize the talking in foreign languages as people are sometimes lazy to provide one after every message they type...

@Arjun yeah we could add this clause too

@sai-kartik ,this would prevent me totally

@Arjun 😂😂

if all users know that language, we can skip translation

Yep

Cus there's absolutely no point trying to waste your time in translating

chal bhai chalte h, (let's go now brother)

ok?

lol that looks annoying to type

@CalvinKhor , it is

@CalvinKhor exactly my point. No one will do it then!

gulliver's looks like something too old to read

Want to attend the［webinar]（webinars.wileyresearch.com/webinar/…)?

A book is a book. Period. :P

@CaptainBohemian your brackets are not (), they are （）

which causes the link to not look nice

Want to attend the webinar

actually its the same with your [] symbols

But attending the webinar needs to give out some personal information

you could lie

how are they going to validate your information

@CalvinKhor , what time is it as per GMT?

it is currently 1255 hours in GMT+0

@CalvinKhor , i would like to attend it

the talk is in GMT+8 time

now it is 2057 hours in GMT+8 (i.e. UTC+8)

a Facebook physics group also asks affiliation information to join

facebook already knows where you live, where your mom lives, your favourite food, your political stance, your personality type, who your friends are

@CalvinKhor

Interesting, thanks again!

@CharlieShuffler

you're welcome :)
