[tardy epoch]

you did nothing wrong.

[river compass]

well, I am glad

[spiral knot]

remove Helpers role if you don't like that

[obtuse pebble]

@river compass Has your question been resolved?

[frosty spoke]

can you describe what you're doing / trying to do without so many big words? are you trying to model a black box?

[river compass]

I have modelled a black box, but making new data points takes time (almost a minute, in fact). I have obtained several regressors using a symbolic regression library (pySR in particular). I am trying to figure out a method to add new data points in an efficient way, so that I can discard bad regressors and be more confident

[river compass]

in other words, im trying to make experiments that disprove hypotheses

[frosty spoke]

what do you mean by "disprove"? what do you mean by "experiments"?

[river compass]

by "experiment", I mean a list of parameters [x0, x1, x2..] to input into the black box to produce a result, Y.
by "disprove", I mean exactly that. I do not believe the current hypothesis are good enough. Therefore, the optimal datapoints to add to the known data are those that will prove as many regressors wrong as possible (by being far away from their prediction). Since I do not know what Y will be beforehand, my intuition is then to test the points where each regressor's prediction are "maximally separate", by whatever possible definition of it

An example (that comes from a previous test of PySR). Every line is the predicted values of a regressor.
My intuition is then to try and run a new experiment at ~1.3, since thats where every regressor disagrees the most with each other. I would like a general procedure to figure this out, though, not intuition.

[frosty spoke]

okay first of all, what do you mean by "regressor"? You're using that word a lot, and it doesn't line up with the usage that I've seen

[river compass]

a regressor is, in this case, a function that I've obtained as a possible model. For example, f(x0,x1,x2,x3,x4) = x2 + x3/(2* x2^3)

[frosty spoke]

so you have a bunch of models for a particular black box

[river compass]

possible models, yes. They are all bad

[frosty spoke]

what makes you think that they are bad

[river compass]

i actually know how the black box should be (more or less: it imitates a real world process with a known formula), and I also have access to it and can make tests myself. I know these models arent complex enough. The interesting part of the project, though, is to make sure it can figure it out by itself. That way i can test other black boxes I do not know how they work, without me being there to give hidden information

[frosty spoke]

how well do the models fit the data you've given?

[river compass]

the best one is close, but it is missing data I think

[frosty spoke]

what do you mean the model is missing data?

models don't contain data

[river compass]

it is missing data points it doesnt know about, since they are not contained on the datapoints used to find the models. I know the full extent of the model, so I know it is missing characteristics

[frosty spoke]

that doesn't make any sense

a model does not contain data points

[river compass]

I didnt say it contains them

[frosty spoke]

how can something be missing something if it doesn't contain them

that's like saying a gas tank is missing water

are you saying that the model doesn't generalise well to data it hasn't seen?

[river compass]

to miss something also means to not know about

and yes

well, it hasn't "seen" any data, models dont see

[frosty spoke]

model parameters are estimated with data

[river compass]

and if im being even more specific, it doesnt "see" anything at all, since the whole batch of possible models is produced at once by a single program

[frosty spoke]

unseen data refers to data that was not used to estimate the parameters of the model

I still don't know what you mean by a model is "missing" data

[river compass]

the bunch of models weren't trained on the right data in order for them to generalize to the black box model. They were taught chapters 1 and 2 and 4, but 3 ended up in the test as well, and so, failed their exam.

[frosty spoke]

so you're basically saying that the models fit the data they've been giving fairly well, but they don't generalise very well to unseen data

then usually there are two approaches to fixing that: regularisation (adding constraints to the model parameters / putting a prior belief on the model parameters) or giving data more reflective of the distribution of data that you're actually going to use with the model

[river compass]

thats not what I want

It doesnt matter to me how the regressor models are obtained. The problem is, as I said, giving them the right data given that finding datapoints themselves is expensive

[frosty spoke]

well unfortunately it matters how models are estimated, because that directly affects how they perform on real-world metrics lol

[river compass]

You cannot test a pharmaceutical cocktail in all possible dosages

[frosty spoke]

in general, a black box can do whatever it wants with the inputs, and it can make absolutely no sense at all

but that's only in the very strict sense that one can construct pathological black boxes

most real-world problems are not that pathological

[river compass]

This is why I said it imitates a real world process

it is not weisserstrass function

[frosty spoke]

the point is that the estimation procedure is literally what makes or breaks a model

[river compass]

the estimation is fine

[frosty spoke]

you tune your model so it is likely to produce reasonable outputs from the distribution of data that it will actually see

[frosty spoke]

????

if the estimation is fine then what problem do you have? your models are perfect then

[river compass]

for the data they were given, they are fine

like I said at the begining, I am trying to add MORE data to their estimation

[frosty spoke]

that says almost nothing about the quality of the estimation procedure

in particular, there are ways to get models to fit the training data perfectly and completely fail validation against unseen data

[river compass]

I know. So how do I antagonistically add more data to put those models to the test

[frosty spoke]

that doesn't make much sense to do

the overarching goal is that your model does well on predicting on inputs that are drawn from the same distribution of inputs that it is likely to see in practice

[river compass]

no, that is not my goal

it's not the goal of science in general either

[frosty spoke]

that literally just isn't how it works

you can't just say "no I don't want that"

[river compass]

real world scientific testing relies on finding experiments that make or break hypothesis. Michaelson-Morley being a great example: measuring the fastest possible relative speed at the time.

[frosty spoke]

this is literally the goal of prediction

[river compass]

But i am not trying to predict

[frosty spoke]

are you not trying to predict the values of the black box?

[river compass]

no, I am trying to model the black box correctly

[frosty spoke]

that is literally the prediction task

you are trying to predict the values of the black box given the inputs

[river compass]

that is part of it

[frosty spoke]

unless you have some other goal, like interpretability or whatever

but I doubt that

[river compass]

obtaining the data is also part of it, and thats the part I have trouble with

[frosty spoke]

huh?

the data is a means to an end

[river compass]

and yes, interpretability is important but thats why Im using a symbolic regressor

[frosty spoke]

the data is used to estimate and select a model

[river compass]

yes, and data is more expensive than compute time

[frosty spoke]

okay you're completely missing the point

[river compass]

I dont see how I can be missing the point

[frosty spoke]

because you're saying a lot of things that are just contradictory and also just aren't following the basic principles of statistical modeling

[river compass]

this isnt statistical modeling

[frosty spoke]

if you want a refresher on it, I suggest reading the first few chapters of introduction to statistical learning or a similar type of book

what you are asking isn't well-posed or well-defined

literally the most charitable interpretation I can come up with for what you want is that you want a whole bunch of examples on which your current model candidates do absolutely horribly on

and there's research into that that crosses over from deep learning / artificial intelligence involving adversarial examples, the simplest of which are gradient-based like FGSM

but given everything else you've said, I highly doubt that will actually get you any closer to achieving whatever it is you want

[river compass]

if this was statistical learning, there is an standard way of doing what I want

[frosty spoke]

it's a pretty obvious mathematical fact that, given any finite number of examples, one cannot model an arbitrary black box for all input values

and that seems to be what you seek to demand here

so either you need to fix the problem of the black box being arbitrary by putting priors or constraints on it, or you need to solve the input values problem

[river compass]

the information matrix of a set of statistical regressors can be used such that the information content of new data can be obtained. From that, it can be used to find maximal information experiments

Unfortunately, i do not know any information matrix analysis of symbolic regressors

https://en.wikipedia.org/wiki/Fisher_information#Optimal_design_of_experiments

[frosty spoke]

fisher information?

[river compass]

When the linear (or linearized) statistical model has several parameters, the mean of the parameter estimator is a vector and its variance is a matrix. The inverse of the variance matrix is called the "information matrix". Because the variance of the estimator of a parameter vector is a matrix, the problem of "minimizing the variance" is complicated. Using statistical theory, statisticians compress the information-matrix using real-valued summary statistics; being real-valued functions, these "information criteria" can be maximized. ```

[frosty spoke]

you don't need to explain to me what Fisher information is

I learned it in my statistics classes

I highly doubt Fisher information is what you want

Fisher information does not depend on the data

[river compass]

No, like I said, I know it is not what I want, since it deals with statistical regressors

[frosty spoke]

it's used in things like the Cramer-Rao lower bound

it's a total non sequitur

[river compass]

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

"In the design of experiments for estimating statistical models, optimal designs allow parameters to be estimated without bias and with minimum variance. A non-optimal design requires a greater number of experimental runs to estimate the parameters with the same precision as an optimal design. In practical terms, optimal experiments can reduce the costs of experimentation. "

[frosty spoke]

I suggest that you open a book, like the one by Hastie I gave you, and actually study the subject

otherwise you're just quoting stuff from random articles that doesn't make any sense in context

[river compass]

Let me ask you this, what do you think I want?

[frosty spoke]

I honestly have no idea, which is why I asked so many questions, but I got contradictory answers

I told you that my best literal interpretation of what you're asking is that you want examples such that all of your models do poorly

but I can't imagine anyone wanting that because it's mostly useless

[river compass]

I want to design experiments, as stated on my first post

I want to design them optimally, or close to optimal if not possible, as stated on my first post

[frosty spoke]

none of that makes any sense in context though

[river compass]

The optimality is given by the less runs possible

[river compass]

explain the context such that that makes no sense

[frosty spoke]

in the entire context of statistical modeling

like what does this have to do with experiments

[river compass]

I have said, all this time, this is not statistical modelling

[frosty spoke]

it's not like you have come up with a model for your black box a priori and are trying to say yes or no does this model hold

[river compass]

I have corrected you before, saying that "this is not statistical modelling"

[frosty spoke]

you can say whatever you want, but fundamentally your problem falls into statistical modeling

[river compass]

I have also added that, where this statistical modelling, I already know how to do what I want

[frosty spoke]

you want to pick a model such that your black box fits well

[river compass]

no

I want to design experiments such that they are the best possible experiments, given what estimators I have. I then explain what "best" means

[river compass]

I have several estimators already, this is not an issue, I am not trying to generate or tweak or parametrize the estimators, they are a given.

[frosty spoke]

okay you never mentioned estimators before, so I'm going to assume you meant models

and no

you literally estimated the models off the data

I don't want to rehash the basic principles of doing these things, because I feel like I wouldn't do as good a job as all of the resources out there

but I highly suggest actually reading up on this stuff because you're not making much sense

if you're not interested in the statistical inference parts, perhaps taking a look at some of the resources surrounding deep learning on the internet would help a lot

[river compass]

this has absolutely nothing to do with deep learning

this is a design of experiments problem

[frosty spoke]

because that is literally a lot of what they do -- model a lot of complex phenomena that are black boxed out and use data to build models

as I said

you can say all you want, but how do you know you're actually right on that?

[river compass]

what?

[frosty spoke]

you're literally modeling a black box, and a lot of the deep learning basics have insights to the problem that you haven't grasped

things like the bias-variance tradeoff, optimization, overfitting, model selection, regularization

but it's up to you whether you actually want to do the reading or not

[river compass]

Im starting to think I should just give you a bunch of numbers and see if you come up with an optimal method of asking me the right questions

[frosty spoke]

and gathering more data is a part of it too. there are papers about data augmentation, but these are all done with a purpose

and one last bit: it turns out that in decision theory, the criteria for optimality matter a lot, and that vastly different choices become optimal depending on how you look at it

[river compass]

I am unsure where does decision theory come here, could you explain the relationship?

I can think of relationships between what I know of decision theory and Montgomery's Design and Analysis of Experiments (my handbook at the moment), but that would be a guess

[frosty spoke]

decision theory relates to things like statistical hypothesis testing, model selection, estimations

[river compass]

Thats what you meant? I did specify the criteria: number of runs, which is the standard in optimal design

[frosty spoke]

number of runs until what?

I can't give you an answer to your question because I don't understand what you want or what direction you want to go in

none of it makes sense

[river compass]

The optimal design is designed for a certain number of runs, such that the information gained in the experiments is maximized (this is called D-optimal)

you can see it in page 466 of Montgomery's

[frosty spoke]

as I said, I highly recommend reading / watching an introduction to deep learning and learning about the issues that result when using data to build a model

you're just quoting things that don't apply in context

[river compass]

How does what I just said dont apply?

This is exactly what I meant when I said that my problem is that I have no clue how to obtain the information matrices of a design given that it does not deal with random variables

[frosty spoke]

look, I cannot rehash and explain every aspect of the theory involved

your talk about Fisher information matrices makes absolutely no sense in context

[river compass]

you keep saying that, then not explaining how it makes no sense in context

[frosty spoke]

what else would I say? if I told you to use logarithms here, that would also be an example of something that makes no sense in context

[river compass]

I am aware of the language barrier but surely you can see a question like "How does one make a D-like optimal design, given I am not using statistical models?"

All other, particular information, i thought, would help to understand how one reaches this problem

[elfin burrow]

How many of the remaining cards are black?

[obtuse pebble]

@wind panther Has your question been resolved?

[wind panther]

2

[high lily]

please reread the question

[wind panther]

50

[calm mesa]

[high lily]

please reread the question

[calm mesa]

Made my day tbh

[high lily]

i'll break the question down if needed based on your next response

[wind panther]

49?

[high lily]

no

[trail musk]

How many black cards are there in a deck?

[timid silo]

26

[high lily]

not directed at you @timid silo

[calm mesa]

I think they are assuming the entire deck is black which is not

[wind panther]

is it 26?

[royal basin]

yes, there are 26 black cards in a deck.

[trail musk]

Yes! Very good!

[royal basin]

so now that 2 black cards have been drawn, how many black cards remain in the deck?

[wind panther]

24

[royal basin]

correct

so now, there are 24 black cards remaining in the deck.

how many cards in total remain in the deck?

[wind panther]

24+52?

[high lily]

no

[calm mesa]

[high lily]

how many cards are in a standard deck of playing cards (not counting jokers)

[restive fiber]

just use binomial probability formula no?

[wind panther]

52 in stabndard deck

[wind panther]

bro this guy

[high lily]

and after 2 cards have been drawn, how many cards do you have left in the deck?

[wind panther]

52-2

50??

[high lily]

yes

[calm mesa]

Yes

[wind panther]

24+50

??

[high lily]

whuit

what's 24+50 supposed to be

[wind panther]

total?

from???

24?

[restive fiber]

hhh

[wind panther]

.

[high lily]

why are you adding the number of black cards to the number of cards in the deck

[restive fiber]

@high lily @calm mesa

[wind panther]

thought thats how u do it

[restive fiber]

stop the bullying

[calm mesa]

You know you are left with 24 back cards from the remaining 50 cards in total?? Work with that

[high lily]

it's like saying
i'm starting with 100
gave 2 away
leaving me with 98
but the total amount of money i have now is 198

[wind panther]

back?

[calm mesa]

Sorry black

[wind panther]

24/50?

[calm mesa]

Yes

[high lily]

the total Ann is referring to, is simply the cards remaining in the deck

[calm mesa]

Then simplify

[wind panther]

12/25

[calm mesa]

Anyways sorry for laughing

[calm mesa]

Yes .I think

[calm mesa]

MEAN = $\sum fx \over \sum f$

[warm shale]

Pyp

[wind panther]

i know what mean is

i just dont know what number to put in

do i use all numbers of frequency or score?

[calm mesa]

Draw a table:
f = frequency
fx = frequency* score(x)
Efx = sum of all fx
Ef = sum of frequencies

Then find the mean from that

[wind panther]

okay thanks

@calm mesa

[restive fiber]

[calm mesa]

Form equations then solve

[wind panther]

how to form?

[calm mesa]

X + 115 + x = 180 --> Angles in a straight line add up to 180
X+115 + z = 180
Z+ y = 180
Those should be enough I think

[wind panther]

z and y=90

[calm mesa]

Y?

[wind panther]

arent they both 90?

Z and Y 180?

[calm mesa]

Can't make assumption..Yes

Z + y = 180 since they are on a straight line

[wind panther]

so then X +115+90=180?

wait no that doesnt work

[calm mesa]

You cant assume any angles until you have solved them

Remember sometimes seeing is not what is actually there

Solve the equations I gave in that order then substitute accordingly

[wind panther]

okay so X+115+x=180

Uhhhh

[calm mesa]

Yep

[wind panther]

Big X 30?

[calm mesa]

There is no big X and small x all of them are the same it just my keyboard which is capitalizing the first letter

[wind panther]

Oh

180-115=65?

[calm mesa]

x + x + 115 = 180
2x = 180 - 115
x = (180-115)/2

[wind panther]

32.5

[calm mesa]

Yeah

Then solve the second by substuting the value of x then solve the third

[wind panther]

X+115 + z = 180

32.5+115+32.5

Z=32.5

[calm mesa]

???

Yeah

It's correct

Then solve for y

[wind panther]

z+y=180

180-32.5

[calm mesa]

Yep

[wind panther]

147/5

147.5

[calm mesa]

I think so

[wind panther]

sounds right to me

Sorry for all the questions

[calm mesa]

Try adding all the angles after substituting .If they add up to 360 then it is correct

[wind panther]

Just a new year and New topics

[wind panther]

Okay

[calm mesa]

It's ok

[wind panther]

total surface area for cube is like a^6?

a is like a side

and idk what a side of this shape is it just gave me diagonal

[calm mesa]

If it is closed:
Total surface area = $6 * s^2$
(Assume it is closed if not told)
If open:
TSA = $5 * s^2$
Where s = length of the side

[warm shale]

Pyp

[wind panther]

idk what the length of side is

would it be 4

[restive fiber]

bro

why are you makign them solve all of your homework

[wind panther]

idk just hard

im not making them solve im learning on the procces ☺️

[restive fiber]

this is what you tell yourself

[wind panther]

mate tbh why do u carE?

ur not helping r u?

[calm mesa]

You can find side from Pythogarus -->
$ 8^2 = a^2 + a^2$
$64 = 2a^2$
$32 = a^2$ $\implies a = 4\sqrt{2}$ or 5.6569 to 4.sf

[warm shale]

Pyp

[wind panther]

im thankful hat @calm mesa is willing to help

[restive fiber]

good lukc on your exam

[wind panther]

its tutoring hw

[calm mesa]

Yeah..Had some time

[wind panther]

so the side is 4?

[calm mesa]

So you side, a = can now be substituted in the formula

[calm mesa]

No..it is $4/sqrt{2}$ in surd form

[warm shale]

Pyp

[wind panther]

4sqare 2

and then with that how do we find surface area

[calm mesa]

Or 5.6569 cm in actual length

[calm mesa]

Use the formulae I gave you

[calm mesa]

This one

It's best to use $s^2$ as 32 for more accuracy

[warm shale]

Pyp

[wind panther]

5 x 32^2

?

6 x 32^2

[calm mesa]

The last one

From 6 sides when not told whether it is closed or opened

[wind panther]

i got 6144

is that right?

[calm mesa]

Oh and it's just 32 and not the square of 32

[wind panther]

got 192

[calm mesa]

Since 32 is already squared

Then its correct

[wind panther]

@calm mesa r u free still

or no?

its fine if ur not

[calm mesa]

I'm free

[calm mesa]

Just get the area in hectares and then multiply whatever you get by the 60 kg

1 ha --> 60kg
x ha --> ? kg

[wind panther]

500 x 300?

[calm mesa]

The answer is in square metres..Convert to hectares

[wind panther]

2500 hectares?

500 x 300 =150000
150000/60

is this right?

[calm mesa]

No

Math is not about just playing with numbers ..it is always done to achieve a certain goal

You must have proper understanding to accurately formulate the answers

As much as you have the area you must always remember the units (m ^ 2)

Otherwise you might get confused...

Then when you change to hectares remember you put ha at the end

[wind panther]

yes

so whats the equation for this

[calm mesa]

What I can tell you understand what you are doing otherwise all of this will be just a waste of your time

[calm mesa]

There is no direct equation

[wind panther]

so what do i do?

[calm mesa]

I'll solve this stepwise:
1: What does the question want --> Kg required to be planted in the land if 60 kg are on one ha
2: Ha is a unit of area .So I must get area first but in the end it must end in ha
3: What do I have ? --> The linear dimensions (length and width)
4: Ok. What do I know?

Area = Length * Width
I substitute to get
Area = 500m * 300m
Area = 150000 $m^2$

[warm shale]

Pyp

[wind panther]

yes i agree to that

[calm mesa]

5.What then?? I convert to hectares since
$ 1 ha = 10000m^2$
What about 150000 $m^2$?
This leads to 15 ha

[warm shale]

Pyp

[wind panther]

OHHHHH

Oh NOW I get it

[calm mesa]

Ok. I have area in hectares. Now if 1 hectare = 60kg what about 15 ha

You must have clear understanding of what is happening to actually get to the correct answer

That proper analysis is required

[wind panther]

15ha=900kg

[calm mesa]

Yeah

[wind panther]

ayyy

[calm mesa]

$\calc 15 * 60$

[warm shale]

Pyp
Compile Error! Click the reaction for more information.
(You may edit your message to recompile.)

[wind panther]

yea thats what i did

so 900 kg as the asnswer?

[calm mesa]

Yeaj

[wind panther]

@calm mesa got time in ur hands? still?

Nearly done

like 2 more questions

its fine if u dont

[calm mesa]

And dont be excited when you see a similar question..Always read them twice

[wind panther]

yes

[calm mesa]

Yes

[calm mesa]

There are 2 ways you can solve this

[wind panther]

tell me the easier way

[calm mesa]

Both of them are easy but the first one is simpler compared to the second one

[trail cloak]

Oooo

[calm mesa]

1: Find the volume and then convert to cm3

[trail cloak]

You know how when you get Volume?

[wind panther]

Area times Width or sumthing like that?

Area x Width

[trail cloak]

That's only area
Oo yeah that's it

[calm mesa]

Or convert to cm units and then multiply

[wind panther]

900 x 80?

[trail cloak]

Yep

What's your units?

[wind panther]

72000

mm

[trail cloak]

Okay

And how many mm^3 in 1 cm^3?

[wind panther]

1000

[trail cloak]

Okay so to obtain cm^3, what do you do to the mm^3?

[wind panther]

x 1000?

[trail cloak]

Hmm

[calm mesa]

First way
1: Volume = Area * Length
2: V = 900 * 80 = 72000 $mm^2$
3: 1 $cm^3$ = 10000 $mm^3$

[trail cloak]

Hmm

Those numbers for conversion look sketchy

[calm mesa]

Oh

[wind panther]

wait so i convert 7200mm2 to cm2

[trail cloak]

No no

You got volume

[warm shale]

Pyp

[trail cloak]

$72000 \mathrm{mm}^3$

[warm shale]

VulcanOne

[wind panther]

is that the answer?

[trail cloak]

And you just said that

1000mm^3 = 1cm^3 right?

[wind panther]

yea

[trail cloak]

Okay solve for 1 mm^3

[wind panther]

divide 1000

????

[trail cloak]

Yep

[wind panther]

72000/1000

72?

[trail cloak]

Yeppppp

[wind panther]

72mm^3

[trail cloak]

cm^3

[wind panther]

oops

[calm mesa]

Yes dont forget the units (correct) ones

Nice

[trail cloak]

Oo

[calm mesa]

This questions always made miss that 100

[trail cloak]

Notice how the biggest lengths are the only lengths given

[wind panther]

oh yea tru

so we can find the smaller one with the biggest ones

the under the 30 is 15?

actualls dont wrry abt this one

i can do this by my self

this one gets on my nevres

nerves

THIS ONE SO HARD

pain in the but fr @trail cloak @calm mesa

so i found out

[calm mesa]

Assume that there is no time difference first:
Get the time difference: how long is one time from the other

[wind panther]

March 27th 1:00PM

to

Martch 28th 05:55AM

[calm mesa]

Yeah

[wind panther]

16hrs and 55mins

is that correcvt/

[calm mesa]

Then just add their time back since they moved from a region where time is ahead to a region where time was behind

[wind panther]

6hrs and 55min diffrence now

[calm mesa]

If they had gone where time was infronty u would have hadd to subtract

[calm mesa]

No

[wind panther]

16hrs 55mins - 10hrs?

isnt that what its supposed to be

[calm mesa]

• Since they want back in time

[wind panther]

26hrs and 55mins

[calm mesa]

Yes.. According to me

[wind panther]

and with that 26hrs and 55mins what do i do with that??

oh thats the answer

YOO @calm mesa

IM DONE NOW

u fr a goat

i can sleep now even though 2am at night

UR A G FR

i wish i could give u virtual hug

u being saving life fr

[calm mesa]

Anytime

[thick crystal]

why does this functions is located in 2nd and 4th quadrant?

[trail cloak]

Hmm

When x is from (-infinity, -2), the fraction is positive

Then it becomes negative in between (-2, 3)

Lastly, (3, +infinity), your function will be positive and will approach 1

[silver plover]

hi

[silver plover]

do we only use euclids lemma for prime factors?

ie for this

can we not use euclids lemma since 6 is not a prime factor?

[wise talon]

whats the question

because that statement is wrong if b is a perfect square

[silver plover]

prove sqrt 6 is irrational

[wise talon]

abbotts analysis im guessing

u dont need euclids lemma for this

and no it wont work since 6 is not prime

[silver plover]

when do u use euclids lemma then

[wise talon]

so you are correct

[royal basin]

make your six not look like the lowercase letter b, for a start...

[silver plover]

here we goo

[wise talon]

oh god that was a 6

[silver plover]

Ann patrol again

[wise talon]

I thought it was a b

[royal basin]

well

[silver plover]

then again

[wise talon]

^^

[silver plover]

she has a point

[royal basin]

that only furthers my point doesn't it

yeah

anyway, you could nuke this with FTA i guess

[silver plover]

whats FTA

[royal basin]

fundamental theorem of arithmetic

[silver plover]

oh

[royal basin]

yknow the prime factorization thing

[silver plover]

ye ye

[royal basin]

the exponent on 2 in the prime factorizations is odd on one side and even on the other

and the same for 3

[silver plover]

isnt thos just euclids lemma?

[wise talon]

nope

do you know what the thm statement of euclids lemma is

[silver plover]

Let a and b be natural numbers, and let the prime p be a factor of ab. Then
p is a factor of at least one of a and b.

[wise talon]

yes can you see how

thats not the same

[silver plover]

ye

[wise talon]

"ann patrol" is hilarious btw

[silver plover]

lmao

[wise talon]

but yes do not write your 6 like a b

[silver plover]

ive done the proof

idk if its valid tho

[silver plover]

hows this proof

[wise talon]

yup this is fine

although

you should explain why 6 being a factor of a^2 means

6 must be a factor of a

its probably easier to go with saying a^2 is even

so a is even

and then

[silver plover]

i see

[wise talon]

if your explanation depends on sqrt(6) being irrational then you cannot use this method

[silver plover]

is it fine to just make the statement in a proof that if 6 is a factor of a^2 then 6 is a factor of a?

[royal basin]

well i do get peeved at bad handwriting.

[wise talon]

thank goodness you've never seen mine

[wise talon]

nope, thats unjustified

[silver plover]

how do i justify it then?

[wise talon]

to be fair ive never turned a 6 into a b so

exercise for you

i have no idea if it can be justified without using the irrationality of sqrt 6 btw

[silver plover]

could u just say

6 divdes a^2

a^2 = a times a

so 6 divides a?

[wise talon]

why though

[silver plover]

i was gonna say this is a bit like euclids lemma

but 6 aint prime

[wise talon]

you still havent justified it

[silver plover]

this is an example

[wise talon]

I mean you can finish the proof by just saying

[silver plover]

from my lecturer

[wise talon]

since a^2 is even then a is even

[silver plover]

and he hasnt justfied it

[wise talon]

yes ik what euclids lemma is

because 3 is prime

thats the justification lol

[silver plover]

right

thats same as what i said

basically

[wise talon]

no....

[silver plover]

if 6 divides a^2

[wise talon]

you said 6

[silver plover]

then a divdes 6

[wise talon]

that is completely unjustified

[silver plover]

yh but all multiples of 6 r even

[wise talon]

yes I know

so say its even

[silver plover]

so its kinda the same thing

[wise talon]

no

[silver plover]

why thp

[wise talon]

it is not

[silver plover]

tho

but

thats the markers fault

they should have common sense

for realsing that

[wise talon]

yes, if 6 divides a^2 then a^2 is even

no....

no no no

[silver plover]

😂

[wise talon]

[silver plover]

ok but i get wat u mean

kl

[wise talon]

its an unjustified assertion

6 is not prime so euclids lemma does not apply

if you can prove 6 dividing a^2 implies 6 divides a WITHOUT using the fact that sqrt 6 is irrational

then you can use that

[silver plover]

i see

[wise talon]

otherwise just make your life easy and say 6 dividing a^2 means it is even

[silver plover]

ok

[wise talon]

and this can be justified by either euclids lemma or like some other easy proof

uh no a will not be equal to 6k

[silver plover]

bruh u said it was fine

before

oh is it cuz i changed it now

[wise talon]

sigh

yes

its a proof, you need to think a bit

[silver plover]

allow it got a real analysis exam next week

[wise talon]

yes this is abbotts real analysis book

[silver plover]

and i gotta teach mysef everything in a week

...

[wise talon]

im guessing

good luck lol

[silver plover]

who

this is my lecturers

book

[wise talon]

wait what

oh

maybe prove sqrt6 irrational is a common one

[silver plover]

lma

[wise talon]

i know its in chapter 1 of

understanding analysis

unless he's ur lecturer lmao

[silver plover]

do i use euclid lemma

for the last bit?

[wise talon]

which last bit

[silver plover]

showing that b is even

[wise talon]

sure but no need

2a^2 is even so 3b^2 is even

either 3 is even or b^2 is even

obviously 3 is not even

[silver plover]

so is need?

[wise talon]

yes

[silver plover]

rare L

[wise talon]

i make mistakes all the time tho

its not rare

[silver plover]

how dis now?

[wise talon]

lgtm

[silver plover]

nice

[warm arch]

first semester in college algebra id love to know how to work through and get this answer. also would love to know what "i" is and where its applications are

[wooden cipher]

i=sqrt(-1)

[warm arch]

oh wow

[wooden cipher]

Youll se its application a lot when you get into physics of rotations and stuff

Polar form, de moivres theorem, etc

[warm arch]

so i, in this problem would be sqrt of 5 then -1 ?

[silver plover]

sqrt 5 times sqrt(-1)

i is sqrt(-1)

[warm arch]

im still stuck trying to solve the question at all. i have the answer sure, but i have no idea how to get too that answer. i get stuck somewhere in the simplifying part

[silver plover]

ok so

simplify

the inside

of the sqrt

and tell me what u get

[warm arch]

220

[silver plover]

r u sure?

[warm arch]

yes

[silver plover]

well ur wrong

try again

[warm arch]

-20

[silver plover]

yes

[warm arch]

okay that helped, ive got the process to get sqrt of 5 over 5

[silver plover]

gd

[warm arch]

but at what point does i join in there

[silver plover]

whats another way of writing sqrt -20

[warm arch]

unsure, i know sqrt of 20 is 2xsqrt5 but -20 would have to be a - and + multiplication.

[silver plover]

i said sqrt of -20

so think

how u can use i

which is the sqrt of -1

and re write sqrt -20 using that

[warm arch]

im lost

[silver plover]

sqrt(-20) = sqrt(20) times sqrt(-1)

smh

[dawn quarry]

You invest $400 in a magazine stand. You buy each magazine at $3.00 and you are planning to sell them at $7.00.

[dawn quarry]

My answer would be 400 = 3x + 7

But I’m unsure if this is correct or not

[dawn quarry]

Write a linear function to represent the situation. Choose your own variables.

[digital remnant]

you buy n magazines, each costs $3, for $400

i would want to find the numbers of magazines i can buy

[dawn quarry]

so that’s 3n = 400?

[digital remnant]

mhm

yes

[dawn quarry]

That’s the linear function?

[digital remnant]

not really

it is

but it doesnt help us in this problem

i suppose we want to know how much of a profit we can make

we know that we buy one magazine at $3

and sell it 7

so we buy n magazines for 3

sell n magazines for 7

and find benefits

[digital remnant]

i would solve this equation

have you ever solved equations

[dawn quarry]

Yes

[digital remnant]

nice

do you see where this is going ?

you can tell me

[dawn quarry]

Yes

[digital remnant]

good

[dawn quarry]

I got approximately 133

For n

[digital remnant]

yes

[dawn quarry]

but it’s just asking for an linear function

Not to solve it

[digital remnant]

oh

is it

ok

i didnt know

linear function of buying or selling ?

both perhaps

[dawn quarry]

I think it’s this

[digital remnant]

yes

im sorry

i thought it required the sales

[dawn quarry]

it’s okay

that’s correct?

[digital remnant]

mhm

why the +7

[dawn quarry]

should it be minus 7?

[digital remnant]

idk

what is the question asking for

[dawn quarry]

To write a linear function to represent the situation

[digital remnant]

i dont see why we would need a linear function

we know how much magazines we have

how much we sell

[twin root]

I don't understand this question

[trim locust]

Between what times does the line go up?

[twin root]

I guess 0 hours and 2/3

and it's all down from there

[trim locust]

Ok

So the level of ibuprofen increases between the <BLANK> hours and <BLANK> hours

[twin root]

0 and 2/3

and I am stuck on another one as well..I'm struggling with these graph questions

I realize that it's always going up by 0.6, but I don't understand what it wants me to do

[trim locust]

Hold on let me read it

[twin root]

I'm not use to algebra either so I'm unsure where my x should be

[trim locust]

Let’s clear some of the clutter from the question

That’s the data

[twin root]

Yep

[trim locust]

What column is x which is y

Refer to the question

[twin root]

x = year

y = trunk

diameter

[trim locust]

Perfect

You said they all go up by 0.6

[twin root]

yea

[trim locust]

I think it’s easier to think about this in words
The tree diameter grows 0.6 per year

I put the bits in bold, how much will the tree diameter grow in 2 years

[twin root]

1.2

[trim locust]

How much does the diameter grow in x years

[twin root]

If x = 2 years then 1.2

[trim locust]

But now we want to say how much does it grow every x year where x could be any number

When I asked you for every 2 years, you did 0.6 . 2, now I want every x years you should do

[twin root]

https://tenor.com/view/confused-confusion-cat-white-cat-im-confusion-gif-16828447

Idk wym by x years

AHHH

[trim locust]

Right so

We said x is the number of years right

I picked x = 2 and you told me how much itd grow, you multiplied it by 2

So let’s say we have some number x years, and x can be anyyyy number, how will we know how much it grows? Can you write a formula? Instead of 0.6 * 2 it’ll be 0.6 *...

[twin root]

All I know is every 2 years = 0.6 diameter and so 1 year would more than likely be 0.3

So I could just go year by year

But Idk what it's asking me to write

I'm pretty much noob at algebra stuff

[trim locust]

You know that every year

This tree grows 0.6

[twin root]

It's technically every 2 years right?

[trim locust]

Yeh my bad didn’t read the question close enough, so every year is 0.3

Let’s say the letter x is SOME NUMBER any number whatsoever, and this number represents the number of years

Are you following

[twin root]

Yeah

[trim locust]

How do you work out how much it has grown over those x years, remember it grows 0.3 every year

[twin root]

I just add 0.3 by each year to solve what it would be the next

or 0.6 for every 2 years

[trim locust]

Ok

The number of years is x

So it’s 2*x

[timid silo]

Can someone help me by this

If S (t) = a Cos 2t
Find a (6)

[obtuse pebble]

Please don't occupy multiple help channels.

[timid silo]

<@&286206848099549185>

[tardy epoch]

can you take a picture of the original question

or screenshot

[timid silo]

But its in arabic

[tardy epoch]

the math is what matters

translate the rest

[timid silo]

Ok just a minute

Here is the question

A body moves in a straight line according to the relationship S (t) = a cos 2t, where S: distance in meters and T: time in seconds, a constant that the acceleration of the body when it travels a distance of 6 meters is??

@tardy epoch

[trim locust]

How do you get a formula for acceleration?

[timid silo]

By speed derivation

[trim locust]

Do you have an equation for acceleration

[timid silo]

No i only have the formula of distance

[trim locust]

How do you find the equation for speed

[timid silo]

<@&286206848099549185>

[trim locust]

I'm helping you -

[timid silo]

By the distance derivation

[trim locust]

Can you differentiate the distance function

[timid silo]

-2a sin 2t

[trim locust]

How do you now find acceleration equation

[timid silo]

By speed derivation

[trim locust]

Please may you compute the acceleration function

[tardy epoch]

derivative of velocity* but yea

[timid silo]

So you want to solve it with you step by step??

[trim locust]

?

[tardy epoch]

lewis is walking you through how to do the problem. he's not doing the problem for you

[trim locust]

At some point most people it clicks and you're supposed to realise why you're doing what you're doing, and perhaps suggest what to do next without me telling you

[timid silo]

Can you just give the answer @trim locust

[trim locust]

No

[timid silo]

Why

[steel marsh]

that's not what these help channels are for...

[timid silo]

Ok thank you

[trim locust]

Ok, the answers 93842.3 ms^-2 have you learnt how to do it if you change the numbers

[tardy epoch]

don't

[jaunty sigil]

But that's wrong answer

[trim locust]

Yes of course it is thats why i said it

[jaunty sigil]

So you didn't give him the right answer

?

[trim locust]

I said it to prove a point, they wouldn't know if it's right or not (in context of the question its clearly wrong)

[jaunty sigil]

Oh ok

Thx

[frozen carbon]

I have a point in 3d space, and all properties about the 3d space are relative to the point; the roll, yaw, pitch and X, Y, Z of the point is always at 0, no matter how it moves or rotates in relation to everything else.

If I had a plane x distance in front of the point, and the point rotates y amount of degrees in the yaw rotation (or any transformation of the point possible), is there a formula to reliably calculate the X, Y, Z, roll, yaw and pitch of the plane?

You should have a transformation matrix T1 defining origin to point. The a matrix T2 from origin to plane

Matrix from point to origin should be T1^-1*T2

[frozen carbon]

the origin would be 0,0,0 on the actual 3d space excluding all the point stuff?

[dark stirrup]

I may be misunderstanding the question. You're saying point can move, yet it stays as the origin? So there should be some master reference point somewhere, right?

[obtuse pebble]

@frozen carbon Has your question been resolved?

[frozen carbon]

thats what i meant as the origin in the other message

[dark stirrup]

This is confusing then: "and the point rotates y amount of degrees in the yaw rotation (or any transformation of the point possible)"

because how can the point rotate or translate without another reference point?

[frosty spoke]

a point cannot have roll, yaw, or pitch

doesn't make much sense

you're basically saying that the point is the origin, and rotations are done around an axis through the point

but you haven't specified the axes through the point either

and further, there is no "X Y Z" of a plane -- a plane consists of many points

[deft forge]

Guys I am so lost on this! Someone please guide me!

I did this so far. But I don't know if it is right.

[fallow cove]

yeah

but you have to calculate the decimal digits for b

[deft forge]

Ohh! How do I do the long division for this?

[fallow cove]

just keep going by adding a .0

cuz 355=355.0

and 326=326.0=326.00=326.000and so on

[deft forge]

I really don't understand that.

[fallow cove]

ok

[deft forge]

I know we can find it using a calculator but I don't know the long division method with decimals

[fallow cove]

should be smth like this

[dark stirrup]

btw typo here:

[fallow cove]

oh yeah

should be 326

[deft forge]

Oh my bad!!

I will redo the question

Finished part a

Will attempt part b now

[dark stirrup]

,rcw

[dark stirrup]

Looks good so far

[fallow cove]

yeah

[deft forge]

So do I do 355 divided by 113 next?

[dark stirrup]

113 divided by 355

[deft forge]

So something like this?

[dark stirrup]

,rcw

[dark stirrup]

That's 355 divided by 113

[dark stirrup]

Good so far

[deft forge]

Do I round the last digit?

The 2 to a 3

[dark stirrup]

You have this backwards

should be 113÷160

[deft forge]

Ohh

[dark stirrup]

,rcw

[dark stirrup]

How'd you get 7?

(at 3.7)
