[fair osprey]

Or, which one is 6,2?

[cobalt eagle]

so include whether its going up or down or left or right

and how much its doing it simple

[fair osprey]

Here I’ll give an example
Plotting 1,3
A)go right 1 space
B) go up 3 spaces
This help?

[wary stream]

Or (-1, 5) is left 1, up 5

Just to include a negative

[fair osprey]

Those are quadrants

[fair osprey]

YES THAT 5,5

[elfin fiber]

idk

ok

[cobalt eagle]

i genuanly cant fathom someone not understanding this

maybe its cause im older

idk

[fair osprey]

So, describe how you did that

[elfin fiber]

how old r u?

[kindred nymph]

cam amypme he;[

help*

[wary stream]

Channel busy

[kindred nymph]

sorry

[cobalt eagle]

16

[elfin fiber]

oh

i'm 13

[cobalt eagle]

makes sense

[elfin fiber]

ye

[cobalt eagle]

keep learning yo

[fair osprey]

Chat being used, #help-4 looks empty

[cobalt eagle]

its fun and stuff i guess

[elfin fiber]

oh

that was easy ig

[cobalt eagle]

literally up down left right

[fair osprey]

Exactly but explain how you did it. (I went 6 right, 7up, etc)

[cobalt eagle]

caveman shi

[elfin fiber]

oh

[wary stream]

Use word to explain how you graph that

[elfin fiber]

i went 5 up

and 5 left

ig

[wary stream]

Left?

Why left?

[elfin fiber]

isn't that left?

[wary stream]

Do you know left vs right?

[elfin fiber]

yeah

[wary stream]

Negative is left

Positive is right

[fair osprey]

X is before y (you run before you jump)
Starting from 0,0 going left brings you into -5,0

[wary stream]

so why left?

[elfin fiber]

oh

ok

[cobalt eagle]

do you get it now

[elfin fiber]

yeah

[cobalt eagle]

good job

👍

[wary stream]

If you get it, then reexplain it

[elfin fiber]

noooo

[cobalt eagle]

jesus christ

[fair osprey]

Now do your hw problem and do what dldh06 suggested

[elfin fiber]

the vid?

[cobalt eagle]

ez dur i got you

[silver lichen]

only angle p

[cobalt eagle]

give me two sh1ts

[fair osprey]

Pretend I’m a 5 yr old, and explain how to put 5,5 on their

[alpine sable]

The angle sum of a triangle is 180 so 110+49+3x+15=180

[wary stream]

Ask in a different channel please

This channel is still being used

[cobalt eagle]

frick you bro

[silver lichen]

.

[elfin fiber]

nooo

[silver lichen]

180 the answr?

[cobalt eagle]

hell no

[elfin fiber]

Imao

wtf

[cobalt eagle]

solve for x

[silver lichen]

2

[cobalt eagle]

then add 15

[fair osprey]

Triangles on,y have 108 degrees total

[silver lichen]

17

[alpine sable]

The answer is 3x + 15

So if x is 2 then it would be 21

[silver lichen]

6+15

[elfin fiber]

gimme answer tooo

[silver lichen]

ok 3x

[alpine sable]

Watch the video

[cobalt eagle]

good job

👍

[wary stream]

No

[alpine sable]

Nao stop being a lemming

And go watch the video

[elfin fiber]

fine

[fair osprey]

Watch the entire thing

[cobalt eagle]

literally up down left right

[alpine sable]

Not the first half, or the 7th 8th

[cobalt eagle]

no video required

[fair osprey]

What’s 7th half?

[alpine sable]

No

[cobalt eagle]

my brain just exploded

[alpine sable]

I meant the seventh eighth

[elfin fiber]

ok bye

[alpine sable]

If the angle sum of a traingle is 180, then two angles cant be 90

[elfin fiber]

thank for the help

[cobalt eagle]

what does f(x)= square root of x mean

[alpine sable]

Because then the third angle would be equal to 0 degrees

[fair osprey]

Do you get how to do it now? (Would dms be better?)

[cobalt eagle]

exactly always remeber what the sum of angles are then solve from there

ok time to go do 2 hours of latin homework epic

[alpine sable]

Sounds boring

Enjoy

[elfin fiber]

yeah i get it, but i'm jus too lazy do it rn

[wary stream]

Don't be lazy

[fair osprey]

I’d suggest to do it now, esp if it’s dues tomorow

[wary stream]

Do your work

[elfin fiber]

yeah

[wary stream]

Get it over with

[cobalt eagle]

if she doesnt feel like it she wont do it

[fair osprey]

And, it’s a great chance to practice doing it

[cobalt eagle]

yall dont understand adhd

[alpine sable]

2 + 2 is 3

right

[cobalt eagle]

yuh

dont forget to simplfy

[wary stream]

That mentally will haunt you forever, you saying "I won't do it" will carry with you in the future, making your procrastination worse

[fair osprey]

You can try to encourage them to (idk is encourage is the right word)

[wary stream]

Don't troll

[alpine sable]

im lazy aswell

[cobalt eagle]

shell eventually learn

[wary stream]

No one asked you

[high mortar]

hi guys can u help me solve this problem?

[cobalt eagle]

its not laziness its a lack of innitiative

which is not someting oyu can change overnight

i would reccomend she does it now

[alpine sable]

tak 5 common

[fair osprey]

The assignment according to nao is due tomrow

[cobalt eagle]

as she will have to do it eventually

[cobalt eagle]

ok then do it

i thought she had time

[finite tinsel]

heyy

do yk this sir? @cobalt eagle

[cobalt eagle]

yes

i got you

[finite tinsel]

what is it

[wary stream]

Pythagorean theorem

[cobalt eagle]

12+15+x=36

[alpine sable]

You dont even need it here

[cobalt eagle]

fr

[alpine sable]

36= sum of sides

[cobalt eagle]

making it compliucated for no reason

[alpine sable]

i asked myself

[alpine sable]

Therefore 36-27=x

[wary stream]

It said perimeter, opps

[cobalt eagle]

already said that

[undone isle]

OH MY FUCKING GOD!!!!

[cobalt eagle]

get rekd

[alpine sable]

oh

[cobalt eagle]

yeah im basically smarter

[alpine sable]

ok

[finite tinsel]

so 9=x?!

[alpine sable]

its really not a competition

[cobalt eagle]

good job

[alpine sable]

No, x = 9

[cobalt eagle]

joking

[cobalt eagle]

wasnt serious

[finite tinsel]

lmao thanks

[wary stream]

Doesn't matter, both mean the same

x =9 and 9 = x mean the same

[alpine sable]

x = x

[cobalt eagle]

jeez does no one no how to take joke

[alpine sable]

simply

[cobalt eagle]

fr

x=x^2

if im correct

[alpine sable]

x=1

[alpine sable]

true every kid that is between the ages of 8-15 are little snowflakes

[undone isle]

x = deez!!!!!

[cobalt eagle]

thx yur a life saver

[alpine sable]

Or ±1

[cobalt eagle]

and 0 right

[alpine sable]

You don't compare number to variables, it's always the other way around

Or 0

3

[cobalt eagle]

ok

[wary stream]

You're pretty much assigning the variable some value

[alpine sable]

4+4+6+6

[wary stream]

Add it up

[cobalt eagle]

yur joking right?

[alpine sable]

lemme go back to study keynesian economics now

[cobalt eagle]

wtf is that

[alpine sable]

Perimeter is sum of all sides

[wary stream]

Learn what perimeter is

[alpine sable]

some people are new

[cobalt eagle]

wtf is keynesian

[alpine sable]

its a theory

[alpine sable]

Something to do with the correlation between demand and inflation

"macroeconomic theories and models of how aggregate demand "

[cobalt eagle]

sound niche

[alpine sable]

Exactly I was just telling them the correct way of notation

[wary stream]

I'm saying both work

[finite tinsel]

i dont know anything ab math 💀

[wary stream]

x = 6 and 6 = x

[wary stream]

Then learn?

[cobalt eagle]

addition

[finite tinsel]

you want me to learn so bad teach me?

[alpine sable]

its not so easy as just "learn"

[fair osprey]

Add 4+6+4+6

[alpine sable]

Wow

learning math can be very boring if theres no outcome or goal

[cobalt eagle]

pretty sure you can learn what a perimeter is in a mater of seconds

[wary stream]

Definition of perimeter is sum of all sides

[alpine sable]

i mean yeah thats pretty easy

[wary stream]

You add up all the sides

[alpine sable]

but harder stuff

isnt fun

[alpine sable]

It can be

[cobalt eagle]

elementary school stuff is ez to memorize

[alpine sable]

if theres a outcome yes

[wary stream]

Wasn't referring to the hard stuff

[cobalt eagle]

agreeed it can be really fun and rewarding

[finite tinsel]

math includes the hard stuff sir

💀

[cobalt eagle]

its only hard cause you havnt learned it yet

[wary stream]

Your stuff is basic

[cobalt eagle]

yeah addition is not hard

[alpine sable]

Very basic

[cobalt eagle]

like 2nd grade

[cobalt eagle]

what math are you in

[wary stream]

This is hard stuff

[cobalt eagle]

nah thats ez what you mean

[fair osprey]

Ok, so you have apples layer out in a rectangle shape. Their is 4 apples on each of the shorter sides, 6 on each of the longer. How many total apples are there around the rectangle?

[finite tinsel]

ik how to add

[cobalt eagle]

obviously not

[finite tinsel]

just stuff i sent they never taught me or i either forgot cause of quarantine

[fair osprey]

Att the sides together

[finite tinsel]

whatever.

[cobalt eagle]

how do you forget addition

[wary stream]

If you forget, you google

[cobalt eagle]

what is this

[lone igloo]

can I post here ?

[cobalt eagle]

i think

[wary stream]

See google

[wary stream]

No

[finite tinsel]

i didnt tho

[wary stream]

Maxwell's equation

[cobalt eagle]

what is it used for

[fair osprey]

Add the 4+6+4+6 together

[wary stream]

Electricity and magnetism

Aka physics

[cobalt eagle]

damnnnnn

sounds college level

[wary stream]

Sure

[cobalt eagle]

what does it mean to square root a function

nvm dont answer

i got it

[alpine sable]

I don't think it's college level

[cobalt eagle]

im doing physics next semester

[wary stream]

It is, sorta

[alpine sable]

A wise choice

[wary stream]

AP physics which is college level

[cobalt eagle]

yeah thats what im doing

im taking class at darmouth

since i live near there

im gonna die

[wary stream]

Alright, enough with off topic convo

Channel is open, I believe

[sage vale]

anyone know anything about celestial navigation pls dm me, i got a question

[wary stream]

What topic does this fall under?

[sage vale]

trigonometry sort of

[cobalt eagle]

anyone here good at writing

[wary stream]

Is it more science related?

[sage vale]

ye

[fair osprey]

Why are you asking?

[sage vale]

science and math

[cobalt eagle]

want some feedback on essay

[wary stream]

Because ask in a science server, linked in #old-network

[elfin fiber]

lol

[fair osprey]

If you want, you could dm me?

[cobalt eagle]

that would be awesome

[fair osprey]

Hi, did you finish it yet?

[lone igloo]

anyone could help me with this sequence

[wary stream]

Pretty sure you posted this in a different channel

So don't post in others if you did not get a response yet

[vague iris]

Hi! Is my answer correct here?
Luna sells t-shirts. She sells these t-shirts online. She earns $20 per t-shirts, but she incurs $100 worth of expenses per day. Using this scenario, answer the following:
a. Write a function relating her daily earnings or profit and the number of t-shirts sold.
b. How many t-shirts does she need to sell for her to break even? What does this imply?
Answers:
a. f(x)=20x-100
b. more than 5 t-shirts

[wary stream]

You should repost the question, it got buried

here

[jolly stone]

breakeven means the point where the total sold = cost, so it's just 5 t-shirts

[jolly stone]

is it just me or i cant see

[wary stream]

Same

Can't see it

[merry mauve]

hm, interesting, ill post it again.

[vague iris]

okay. How about the function?

[jolly stone]

yep that is correct

[vague iris]

Yay Thank youu!

[alpine sable]

I need to find magnitude and direction

[wary stream]

For each part?

[alpine sable]

yes

[wary stream]

Do you know how to find x and y components?

[alpine sable]

kinda

I tried to find the x component of B and it gave me a negative 14.820

not sure why it's negative

[wary stream]

Like Rx = Rcos(theta) and Ry = Rsin(theta)?

[alpine sable]

yes

[wary stream]

Perhaps you are in rads and not degrees?

[alpine sable]

I am on degrees

[wary stream]

How did you calculate the x component?

[alpine sable]

for B vector I multiplied 15sin(30 degrees)

[elfin fiber]

it's 10:56 pm

oof

[obsidian forge]

Hey ! Is this channel available?

[dull shore]

yo

anyone know how to solve this

im really confused

[wary stream]

You use transformation properties to describe those functions

[dull shore]

can u solve one of these questions so i can get a better understanding of it?

am visual learner

[wary stream]

You can look up videos

[dull shore]

what would i search up

i tried to find some but couldnt

[wary stream]

Transformation properties

[dull shore]

ok

wait so would i need to graph this

i searched it up and it just shows graphing

[wary stream]

https://www.khanacademy.org/math/algebra2/x2ec2f6f830c9fb89:transformations

There

[dull shore]

do i jsut look at all the vids

or a specific section

[wary stream]

You can look at specific ones

[dull shore]

would this be the same type of question as the one i sent

despite the different letters

like g turns into y

[wary stream]

It's the same concept

[dull shore]

so yes

[wary stream]

But watch the videos instead

Hi everyone

[vale bough]

How to factorize question 25

[fierce frigate]

can someone help me with this?

[vale bough]

bruh the question is in used

[vale bough]

this

[fierce frigate]

what

[vale bough]

<@&286206848099549185> over 15 minutes passed

[vale bough]

this question is not answered

[dull shore]

how to solve

[fierce frigate]

people cant ask at the same time?
/gen

i once asked a queestion and someone asked when i didnt finish yet lol

[alpine sable]

I would start by multiplying everything out and finding a common factor and looking to factor from there

[vale bough]

ok

[vale bough]

sad is not the answer

[alpine sable]

What did you get after factoring?

[vale bough]

the answer should have 3 terms

but only 2 terms

[alpine sable]

What terms did you get?

[vale bough]

9k(14k-49)

[alpine sable]

Hmm, thats different from what I got.

[vale bough]

I need to use identities

[alpine sable]

How did you get that?

Run us through what you did

[vale bough]

first 50k-2k(2k-7)(2k-7)
100k^2-8k^2+34k^2-350k+28k-119k
126k^2-441k
9k(14k-49)

[rugged thistle]

Can you check my computation?

[alpine sable]

It looks like your first step is a little off. You also don't have to multiply everything out in one step.

I would go from
50k-2k(2k-7)^2 to
50k-2k(4k^2-14k+49)

[vale bough]

ok solved

[alpine sable]

You got it?

[vale bough]

yes

[alpine sable]

👍

[vale bough]

cus why not

[alpine sable]

Well yea that's one way to do it

[orchid hull]

Signals question, I am confused about this, wouldn't the product of x[n] and u[2-n] here just be a graph that looks identical to x[n]?

[sinful relic]

Is it true that when u solve equations and u have to plus or minus u only do it with one term but when u divide and multiply u do it with every term

[orchid hull]

that sounds correct

[vague iris]

How do you say like the v(t) as a function of speed?
"Let v(t) be the function of ..." Idk the next words

do i need to specify the variables?

Okay how about this. Is this correct, "Let profit P(t) be a function of the number t-shirts t sold"?

Ohh okay. Thank you so much!

[stuck jolt]

Id rewrite using the identites

what can cos(3x) be written as?

[fervent anchor]

Who ping me?

[golden nymph]

Triple angle

Or you could say

x+2x and compound angle

[alpine sable]

This isn't maths but anyone know the answer (it's computer science)

can someone tell me the working to converting 2.513274123 m² into cm²

[golden nymph]

#❓how-to-get-help rule number 6

[alpine sable]

pls dm me

[golden nymph]

😀

No

[golden nymph]

m is 100cm
By the same logic
m^2=(100cm)^2
=10000cm^2
So that number m^2=that number times 10000 cm^2

[alpine sable]

ok thank you both

[golden nymph]

Didn’t notice you helping

[alpine sable]

im behind on math so this will help me

[vital pine]

Can someone help me with this!

[golden nymph]

That’s one evil question

Actually no

You just need volume of cone in terms of a and h

Minus volume of cylinder in terms of r and x

But then the difficult part is

Finding x in terms of the other so it doesn’t end up in your expression

Others*

[alpine sable]

Yeah, it's going to be 16*32*8

[golden nymph]

Which can be done by taking a cross-section and using similarly of triangles

[golden nymph]

Times 3?

Because three channels of colour?

[alpine sable]

Why would you multiply it by 3

[golden nymph]

Or does it literally mean 8 colors

[alpine sable]

I assumed it did

[golden nymph]

@vital pine

[alpine sable]

It just says it "uses 8 colors" therefore 8 numcomponents

[vital pine]

oh ok, thanks!

[alpine sable]

So you just multiply the height by the width by the numcomponents

[golden nymph]

Yeah that’d be one poor quality picture imo lol

[alpine sable]

So the answer would be 4096 bytes

[tough hatch]

careful, there is a typo in the first statement. (the radius of the right circular cone is definitely not r

[golden nymph]

Nooo

The first statement is the law

[vital pine]

yeah it is h

[alpine sable]

Why the sad cat reaction

[golden nymph]

It is sth different

Coz the cat is sad?

[sage summit]

because you only need 3 bits to tell which colour a pixel is having among 8 possible colours

[rustic rock]

its looks ez

1/8

[sage summit]

also then divide by 8 to get size in bytes

[rustic rock]

0.125 for each colour

[golden nymph]

Ohhhh oops

[alpine sable]

Oh

[rustic rock]

?

[sage summit]

a byte is 8 bits

[alpine sable]

That makes sense

[rustic rock]

see

[golden nymph]

Forgot about that bit byte part

[rustic rock]

so every bit have a colour

[sage summit]

no

[rustic rock]

mean in 1 byte you have random chanse of 0.125% to get colour ?

[sage summit]

what...

[rustic rock]

what the ....

[alpine sable]

Says its wrong apparently

[alpine sable]

Yeah it is, I messed up

[alpine sable]

Here is what I messed up

Wait so what's the calculation

[alpine sable]

I believe it would be (32*16*3)/8

I think

No guarantees

Thanks

God bless u have a great day

My computer science class says thank you

So it was correct?

Yeah

[vital pine]

@golden nymph sorry, im not able to figure it out still 😦 if you dont mind, can you solve it and show

[tough hatch]

no need to post your question on another channel

[vital pine]

can i add (1) to [(2) - (3)]

@tough hatch

i basically wanna add the volume of upper half of the cone to the (volume of frustum minus volume of cylinder)

[golden nymph]

Why is that

Just do whole cone minus cylinder

[vital pine]

but you wont get all the terms theyve asked for will you?

[golden nymph]

Yaaaay

Yas

[golden nymph]

Thing is

You subtract the cyliyndrr from the cone

But this will give us h, a, r and x

[vital pine]

yeah i tried that but im not getting the terms theyve asked for

[golden nymph]

But in the given they don’t have x

So what we should do is

Find an expression for x

And substitute it

This way we can eliminate the x and get to what we want

[vital pine]

ok lemme try it

[golden nymph]

You got that part?

So do you have an idea how can we eliminate the x?

[vital pine]

im working on it

[fierce frigate]

how do i do this?

[golden nymph]

Logs

[fierce frigate]

?

[golden nymph]

First express this ugly mixed fraction as a cool improper fraction

[fierce frigate]

HAHH

[golden nymph]

That’s the first thing to do anywhere

[fierce frigate]

yea did that

[golden nymph]

Ok

[fierce frigate]

got stuck there

[golden nymph]

What does fractional powers mean?

[fierce frigate]

oh and i cannot use calculator for my teeeest tomorrow

[golden nymph]

Do you know what x^(1/2) means?

[fierce frigate]

1/2 is a squaree root

[golden nymph]

Yes

[tough hatch]

what kind of activity is this?

[fierce frigate]

revision

[golden nymph]

Exponent laws

[tough hatch]

can you ss the webpage?

[fierce frigate]

no it has my creedentials

this is my past quiz

im revision

im not new here, i know that i shouldnt cheat

[tough hatch]

[golden nymph]

I think they want to confirm it’s not a quiz

Ya

[tough hatch]

wdym by 'revision'?

[golden nymph]

It means sth cool I suppose

[fierce frigate]

i have my midterm tomorrow...'

im trying to relearn it

so i could understand

[golden nymph]

Idk I feel I can trust this wizard cat

So what’s the power?

[fierce frigate]

i dont know

[golden nymph]

Nani?

Is that omen?

Yeah I play that game

Just didn’t notice that’s him

So the improper fraction

What did you get

[fierce frigate]

hre proof

see thee date of the quiz?

08/09/2021

[golden nymph]

Yeah

[fierce frigate]

3/2

[golden nymph]

So

Can you remove the power and get it to the other side?

[fierce frigate]

is 3/2 cubic root?

[golden nymph]

No

1/3 is

[fierce frigate]

oh ok

[fierce frigate]

i dont know how to

[golden nymph]

Do you know how to do that?

Ok

Removing the power is making it become 1

As x^1 is just x

[fierce frigate]

hah?

[golden nymph]

So we can use the rule that $(x^a)^b=x^{ab}$

[fierce frigate]

ohh

[ocean seal]

ZozzDude

[fierce frigate]

yea that

[golden nymph]

So we can apply 2/3 power both sides

It will cancel

[fierce frigate]

ohhhhhhhhh

so n+1 - 1000

n + 1 = 1000

[golden nymph]

Apply both sides

[fierce frigate]

n= 999?

AHHADJKLADS

idk

[golden nymph]

Don’t magically make it disappear

[fierce frigate]

mkay

[golden nymph]

Is this cie or edexcel

[fierce frigate]

(n+1)^3/2 = 1000
(n+1)^3/2 = 1000 ^3/2
n+1 = 1000
n= 1000-1
n- 999

[golden nymph]

Dude umm

What’s that?

[fierce frigate]

oop

3/2

not 3/4

so like that?

[golden nymph]

That’s not math

That’s crime

[fierce frigate]

what

im confusion

is it wrong or not T_T

pls i beg u

[golden nymph]

It is

Jut calm down

[fierce frigate]

mkay thank you so much

[golden nymph]

?

[fierce frigate]

been stuck in that question for hours

[golden nymph]

Noo

It is wrong

Ahhh

[fierce frigate]

what

[golden nymph]

No

[fierce frigate]

oh

ok

[golden nymph]

Do it slowly

Step by step

First step is apply the 2/3 power to both sides

Just put it there

How will it become?

[fierce frigate]

2/3?

[golden nymph]

?

[fierce frigate]

isnt it 3/2 tho?

[golden nymph]

Apply the power both sides

We apply the reciprocal

That way it cancels

[golden nymph]

This

[fierce frigate]

what that?

[golden nymph]

The 1/it

We want to multiply 3/2 by sth that cancels it

Which is 2/3

1/x is called the reciprocal of x

[fierce frigate]

(n+1)^3/2 = 1000
(n+1)^3/2 = 1000 ^2/3

lik that?

[golden nymph]

No

Dude

When you make a change

In an equation

This change has to be evident in both sides

[fierce frigate]

so both of them turn 2/3?

[golden nymph]

What you sent means that (n+1)^3/2 magically means two things at once

Which is incorrect

[fierce frigate]

sorry, im just so confused

teest

why cant i snd anything

oh finally

[fierce frigate]

ok

[golden nymph]

It becomes $((n+1)^{3/2})^{2/3}=1000^{2/3}$

[ocean seal]

ZozzDude

[golden nymph]

Yes that’s more like it

See?

[fierce frigate]

ok

[golden nymph]

All I ever wanted was to put the power both sides

Can you see that?

[fierce frigate]

HAHA yes i do

[golden nymph]

Take it step by step

[golden nymph]

Next thing we do is use this rule

On the left side

Without changing the right side

Can you use it?

[fierce frigate]

how do i multiply that without calculator

how do i count that*

not multiply

[golden nymph]

You want to multiply 2/3 by 3/2

[fierce frigate]

thats 4/6 or 1/3

[golden nymph]

Count what?

Nani?

[fierce frigate]

idk

[golden nymph]

What are you doung?

[fierce frigate]

im confused

[golden nymph]

Hey

[fierce frigate]

multiply this?

nvm

wrong calculations

[golden nymph]

$(x^{a})^{b}=x^{ab}$

[ocean seal]

ZozzDude

[golden nymph]

Can you see that?

[fierce frigate]

ys

[golden nymph]

Do you know this rule?

[fierce frigate]

no not really

[golden nymph]

You should

Did you memorize your indices rules?

Coz if the problem is that you don’t have your tools ready, you can never do what you want

You can’t remove a screw with a wrench

Are you with me?

[fierce frigate]

no i havent, thee teacher just gave us it, and then skipped to the next chapter the very next day

is it this?

[golden nymph]

Yes

You should memorize all these

[fierce frigate]

ohhhhhhhhhhhhhhhh

[golden nymph]

What you need to solve the question is the third and last one

[fierce frigate]

wait is it
(n+1)^3/2 or (n+1 )^ 2/3?

[golden nymph]

🤦‍♂️

[golden nymph]

..

[fierce frigate]

no not that

[golden nymph]

What?

[fierce frigate]

og

that

ncm

[golden nymph]

In other words, neither

I applied the 2/3 over the existing 3/2

So I can use rule number 3 to turn the power into big ol’ 1

Then I can use rule 4

On the right hand side I can use the last rule to simplify what the 1000^2/3 really is

That way I can eliminate all indices and solve the question

Try to do it now

After that memorize all the rules

[fierce frigate]

((n+1)^3/2)2/3) = 1000^2/3
(n+1)^1 = 1000^2/3
n+1= 1000^2/3

[golden nymph]

Yes

[fierce frigate]

like this? (temporary)

[golden nymph]

Yes continue

[fierce frigate]

and then number 4?

or stil number 2?

oh

[golden nymph]

You already used it

[fierce frigate]

i mean 3

[golden nymph]

.

Continue from here

[fierce frigate]

((n+1)^3/2)2/3) = 1000^2/3
(n+1)^1 = 1000^2/3
n+1= 1000^2/3
n+1 = 1000^-1

?

i dont know

[golden nymph]

What

Please

Don’t randomly change stuff

2/3 doesn’t suddenly become -1

[fierce frigate]

oh yee sorry sorry

[golden nymph]

The last one here has a fraction

Use it

[fierce frigate]

im really sorry

but i dont understand?

[golden nymph]

Use the last rule in the table of rules you gave

Use it to simplify the 1000^2/3

[fierce frigate]

((n+1)^3/2)2/3) = 1000^2/3
(n+1)^1 = 1000^2/3
n+1= 1000^2/3
n+1 = 3 (square root) 1000^2

?

wait a damn minut

fuahkdfgaj

[golden nymph]

It’s called cube root

[fierce frigate]

yea

i waas about to say that

[golden nymph]

Cube root the 1000 then square it

[fierce frigate]

haha

[golden nymph]

What will it be

[fierce frigate]

100

cubee root is 10, square it, 100

is it? that

[golden nymph]

Exactly

[fierce frigate]

oh ok ok, so its

[golden nymph]

Btw

[fierce frigate]

n = 99?

[golden nymph]

Is that cie or edexcel?

[fierce frigate]

whats that?

[golden nymph]

Yes correct

[fierce frigate]

the website i use?

its moodle

[golden nymph]

Arent you taking igcse?

[fierce frigate]

yess

yes i am

[golden nymph]

What board

[fierce frigate]

what

[golden nymph]

Which company provides the exam

[fierce frigate]

i dont know, havent looked deeep into it

[golden nymph]

Don’t tell me you don’t know

😩

[fierce frigate]

i dont live in the uk...

i live in a third world country

[golden nymph]

Igcse means not in uk

[fierce frigate]

oh yea

that

idk

[golden nymph]

And there are three boards governing it

[fierce frigate]

im in south east aasia

[golden nymph]

Cie edexcel and oxford aqa

I took igcse too

[alpine sable]

who decided 0⁰ is 1

who decided 0 multiplied by 0 is still 0, but 0 to the power of 0 is 1

[golden nymph]

Lol

They just defined it to be so for their convenience

But it’s according to context

[fierce frigate]

how do i find out my board?

[alpine sable]

lets truly define 0⁰ 😈

[kindred hull]

ik why its one

wait

nvm its underfined

its 0 in my book 😈

[alpine sable]

yeah its undefined in some cases

[kindred hull]

@alpine sable is that the real zuhn

[alpine sable]

but generally 1

nope he quit months ago bro

[sick ledge]

what is the fastest way to learn set theory for linear algebra?

like is there a video that you guys recommend that is a full course and not super lengthy?

thanks in advance

[golden nymph]

Ask your teacher I guess

[fierce frigate]

thanks for before, so sorry if i was annoying you

[golden nymph]

Nah

You’re welcome

[golden nymph]

Find it

[misty holly]

this is just an error right?

[golden nymph]

Yeah they forgot the 2

[misty holly]

okay okay, that's all thank you

[golden nymph]

And the 8

Have fun!

[misty holly]

ty!

no actually, there's another one

another error?

same sets btw

and answer is supposed to be a null set right?

[hushed pasture]

yes

[misty holly]

mkay mkay, ty

[mystic sinew]

what's the notation for writing quotient of (x/2)

[vernal dragon]

apparently it is

[ocean seal]

Chai T. Rex

[oak chasm]

This ^

[coral cosmos]

Any idea of how can I solve this and get an answer in terms of a and b

[alpine sable]

Finite arithmetic series formula

[alpine sable]

make it equal to a constant

[coral cosmos]

Yup I did that, but the algebra is the problem now.. answer comes out to be a/2 + b/2 - 1

[alpine sable]

then multiply both sides by the denominator

[alpine sable]

What exactly is the issue you have?

[coral cosmos]

I am confused of how to proceed with the question...

[coral cosmos]

and then .. ?

[alpine sable]

Is the question to simplify this expression?

[alpine sable]

the series starts with a and ends with b

[alpine sable]

I assumed that this is the case

[coral cosmos]

Yeah

[alpine sable]

so you can write it out if u want

is ur problem with the algebra or with the sigma?

[coral cosmos]

Algebra ...

The Sigma 'k' = b(b+1)/2 + b - a (a+1)/2 - a isn't it

[alpine sable]

$\sum_{k=a}^b (k+1) = (b-a)a+\sum_{k=a}^b (k+1-a)= (b-a)a+\sum_{k=0}^{b-a} (k+1)=(b-a)a+(b-a+1)+\sum_{k=1}^{b-a} k$

[alpine sable]

ok so write the series out and then just isolate a then b

[coral cosmos]

Oh, thank you so much both of you : )

[sinful relic]

Is it true that when u solve equations and u have to plus or minus u only do it with one term but when u divide and multiply u do it with every term
and why's it like that?

[alpine sable]

From that word salad I'd guess that you'd want to look up distributivity.

[sinful relic]

uh

not like that

2 + 5 * 4 + 3 = 10 + x

If you want to multiply something, for example 2, you have to multiply every term, resulting in 2 * 5 + 2 * 5 * 5 + 3 * 2 = 10 * 2 + x * 2

But if you decided to minus or plus, you only have to do it to one term

e.g. minus 2 from both sides, only with one term, not all

[whole herald]

well, it's algebra

[ionic jewel]

it's because $2\cdot(a+b) = 2a+2b$, but $2+(a+b) = 2+a+b$

[alpine sable]

Note that
$$a+b=c+d$$
$$\implies e(a+b)=e(c+d)$$
Distributivity tells you that
$$\implies ea+eb=ec+ed$$

[whole herald]

when you multiply 2 you have to do it on both sides, otherwise there's no equality

Same thing with any number a

When you subtract 2 you have to do it from both sides, otherwise there's no equality

[alpine sable]

Addition interacts differently with addition than multiplication

[whole herald]

everything you do on one side, you have to do in the other.

[alpine sable]

That doesn't address the question at all

[whole herald]

also, remember that multiplication is a lot of sums

when you multiply everything by two you're just adding the same terms twice

[strong karma]

I have a general doubt can I ask ?

[whole herald]

$2(a+b) = 2(c+d) = (a+b)+(a+b) = (c+d) + (c+d)$

[ocean seal]

kvictor

[strong karma]

can you tell me ?

now as this channel is free

[wary stream]

Not in this channel since it’s being used

[strong karma]

ohk thanks

[whole herald]

I think we ended already

[sinful relic]

No

[whole herald]

you can ask @strong karma

[sinful relic]

we didn't

that doesn't make sense at all

[strong karma]

im on ques 1 sorry

[whole herald]

tell me which part you got confuse, I'll try to help you there

[wary stream]

Don’t answer for people, if the asker hasn’t answered for more than 30 mins or declared it’s free, assume it’s still used

[sinful relic]

3x + 4 = 7 + 6
multiplying with 2:
3x * 2 + 4 * 2 = 7 * 2 + 6 * 2
why not just 3x + 4 * 2 = 7 * 2 + 6 - instead of multiplying all terms but only one on both sides

and when you have
3x + 4 = 7 + 6
and you use addition or subtraction

you can for example add 50 to both sides

where it will only add to one term

that's what i don't get

[alpine sable]

Because of this

[whole herald]

Imagine that, 3x + 4 = 7 + 6
the real question here is

[whole herald]

what is multiplication

[small cypress]

I need help plz

[whole herald]

when you're treating equations

[sinful relic]

So what you're saying is when you multiply, you apply the distributive law and add the question in a parenthesos

prenthesis

parenthesis

[whole herald]

yeah, but there's more

you have to treat that as equal

[alpine sable]

$$a+(b+c)=(a+b)+c=a+b+c$$
because of associativity but with multiplication we have
$$a(b+c)=ab+ac$$
which is distributivity. This happens because you mix addition and multiplication. Whereas if you only use addition you have associativity and you can leave the parenthesis

[ocean seal]

Available

[whole herald]

more generally, when you're working on an equation, you have to do stuff in order for it to continue equal on both sides

you can imagine that

3x + 4 = 7 + 6

[worn ore]

grade ?

[whole herald]

let's call 3x+4 = a
and 7+6 = b

a = b

when you multiply by anything, let's say: 2

then you have:

2a = 2b

let's redo a and b

2(3x+4) = 2(7+6)

[alpine sable]

What

[worn ore]

class

[alpine sable]

Bread

[whole herald]

and then you do Distributivity

[worn ore]

understandable

[whole herald]

and then everything will be multiplied by 2

got it @sinful relic ?

or is that still confusing you

[sinful relic]

I understand 50% of it

ok, so let's say you have

2 + 5 * 4 + 3 = 10 + x

[whole herald]

right

[sinful relic]

don't write an essay about it

tho

try to keep the important

things

so

[whole herald]

continue

[sinful relic]

that's the same as

(2 + 5 * 4 + 3) = (10 + x)

you just normally don't write the parenthesis there

but there is an invinsible one?

right

[merry pendant]

h-help 😢

[whole herald]

Yeah, you can say that

[merry pendant]

i only solved b

[sinful relic]

@merry pendant channel occupied

[whole herald]

#help-2

[merry pendant]

😩

[tepid ferry]

Thank you very much. I’ll give it a try when I get home

[merry pendant]

SHRUREJNDWNDKACNAOA

[merry pendant]

:(

[sinful relic]

2 + 5 * 4 + 3 = 10 + x

but can you explain me why i have to add the parenthesis

e.g. if i want to multiply by 2

[whole herald]

Yeah, absolutely.

[alpine sable]

You apply the multiplication by 2 to both sides

[sinful relic]

i know?

[whole herald]

When you want to multiply the equation by 2, you have to multiply EVERYTHING by two

and the notation for that is

2(2+ 5*4 +3) = 2(10 + x)

and when you apply the distributive

each term individually will be multiplied by two

and let's look at simple stuff

[sinful relic]

stop

[alpine sable]

If you have a=b then you multiply by c so you have ca=cb.
Now take a=2+5•4+3, b=10+x and c=2 then you have your scenario

[sinful relic]

i didn't ask how to calculate it

i'm asking why

[whole herald]

Yes

[sinful relic]

u have to write

(2 + 5 * 4 + 3) = (10 + x)
instead of
2 + 5 * 4 + 3 = 10 + x

[whole herald]

I know, I'm showing you why your method doesn't work

yeah

[alpine sable]

The question of "why" would probably be a little more involved

Do you know what a function is?

[whole herald]

Stop bro

if we both try to explain it to him, it will get more confusing

when you stop I'll explain for him

[devout sigil]

If I have a pack of cards and each pack of cards has 52 cards, I multiply by 3 to get three packs of cards, if I don’t add the parenthesis and only multiply one card I only have 1 packs of cards and additional 2 cards, not 3 packs of cards which should be derived from the product.

[sinful relic]

wtf does that have to do with it just answer why it has to be written as
2(2 + 5 * 4 + 3) = 2(10 + x)
instead of
2 * 2 + 5 * 4 + 3 = 2 * 10 + x

[whole herald]

Yeah

I'll tell you why

look at this simple equation:

2 = 1 + 1

let's multiply it by 2, your method

2 * 2 = 2 * 1 + 1

4 = 2 + 1

4 = 3

that does not work

you have to multiply EVERYTHING by two in order for it to work.

[alpine sable]

I was explaining it, then you joined this with your own explanation so why are you telling me that

[whole herald]

2(2) = 2(1+1)

[whole herald]

because you're not helping

[whole herald]

distributive: 4 = 2 * 1 + 2 * 1
4 = 2 + 2

got it @sinful relic ?

[alpine sable]

And you are?

[whole herald]

Ask him.

[sinful relic]

not really

you told me it would not equal the same if you don't multiply by everything

[golden nymph]

A function is a function that acts like a function

[sinful relic]

but isn't it in general because a = (a)

[sinful relic]

what does that have to do with functions?

[whole herald]

the notation (something)

[golden nymph]

Idk

[whole herald]

is just for you to know

[golden nymph]

Dont mind me

Sorry

[whole herald]

that you have to multiply everything

[alpine sable]

There is a way to kind of get it by example but not really and then there is also a way to get why this is the way we do it.

[whole herald]

I mean, I'm not getting what you're not understanding.

[sinful relic]

@whole herald you are telling me that its because it wont equal the same if you dont multiply by every term but im asking more that you have to think of 6 as (6) but sometimes you just dont add the parenthesis because its redundant

[whole herald]

can you give an example of when it's redundant?

[sinful relic]

6 + a

(6 + a)

[whole herald]

in that case, if you had an equation:
6 + a = b
(6 + a) = (b)
multiplying by two
2(6+a) = 2(b)

it's redundant for b

because b is already only one term

so you don't need to add the parenthesis

you just need to add it when you have more than 1 term
