[alpine sable]

is there any way to know what x and y are in the case of
4=x²+y²

[raven haven]

can be anything

[alpine sable]

because it could be anything I feel like

yeah xD

[steady basin]

how r u supposed to use

C^-1

[keen mason]

inverse matrix

[steady basin]

well

u cant use the inverse matrix of C here

is it just a typo in the question?

maybe it should have said 2x + 4y??

[worn fox]

That would make more sense

[steady basin]

thats a disgrace

isnt it

[keen mason]

XD

[worn fox]

Well now you have two different problems you can solve

Extra practice

[steady basin]

nah

i cba

ill do 1

[steady basin]

how did they get that

question is rigged

[sly mantle]

see your notes on how to compute eigenstuff

[steady basin]

i know how to

but the mark scheme is clearing wrong

[sly mantle]

ah the (2,2) entry

[steady basin]

yessir

[sly mantle]

the original C has ugly eigenvalues so id stay with the solution

[steady basin]

ye

[hollow sparrow]

a typo in matrix C i guess

[sly mantle]

yes the typo leads to ugly eigenvalues

[hollow sparrow]

your mark scheme contain a lot of errors lol

in Calculus now in linear algebra

[steady basin]

yep

[steady basin]

u know for this

i worked it out

and star is commutative

but i found its not associative

but it says show that its associative

?

[sly mantle]

can u show its not associative

[steady basin]

^

agree?

[sly mantle]

to show * isnt associative u just need to give me specific a,b,c where equality fails

[steady basin]

normally in all the questions ive done it wants full proofs

but yh

counterexample would work

but my point is

the question asks to show its associative

but ive proved it isnt

so whos right the question or me

[sly mantle]

to prove * is associative we show (ab)c=a(bc) for all a,b,c
to prove * is not associative we show (ab)c!=a(bc) for some a,b,c

so if u believe the latter, i need specific a,b,c

[steady basin]

a separate MS showed this

guess im correct

wohooo

[steady basin]

MS says alternatively

so i guess u dont need a counterexample

[sly mantle]

if i wanted you to go all the way, id ask you to show those two expressions arent always equal

then youd need to pick specific a,b,c

in general what i said is how to prove a property about an operation, but if a full proof isnt needed and both you and the reader are strong enough at algebra then the above argument can be accepted

[royal matrix]

hi

[royal matrix]

please

im really crap at maths

[vale wigeon]

if this said Work out 29 - 28 would you be able to do it?

[royal matrix]

uhhh

1?

[vale wigeon]

yes

[royal matrix]

so is that the answer?

[vale wigeon]

also, word of advice: don't go around crying about how "bad at math" you are. it's not going to attract more helpers.

yes, 1 is the answer.

[royal matrix]

YAY tysm

how about this one?

would it be

39+13

[vale wigeon]

no, it would be 39 - 13.

[royal matrix]

26?

[vale wigeon]

adding -13 is the same as subtracting 13.

yes

[royal matrix]

omg i love this server

[royal matrix]

so if thats the case

would this be

uhhhh

20?

or 8

[vale wigeon]

you are subtracting +6 from 14

+6 is just 6

[royal matrix]

ohhh so 20?

[vale wigeon]

no

you are subtracting 6 from 14

surely that will not give you 20

[royal matrix]

hmm

8?

[vale wigeon]

yes

[royal matrix]

forthis one

it wouldbe

19?

[vale wigeon]

yes

[royal matrix]

FIRST TRY

YES

can i be honest

discord is the last place i would have thought to get help with my maths homework from

uhh what does the brackets mean

[vale wigeon]

nothing special

[royal matrix]

so it would be 42?

[vale wigeon]

it is visually unpleasant to see two minus signs one directly after the other

no

-32 - (-10) = -32 + 10

= -22

[royal matrix]

so the answer is -22?

[vale wigeon]

yes, as i just said.

[royal matrix]

sorry my dyslexia is kicking in

for this one

it would be

10?

-10

[vale wigeon]

-10

[royal matrix]

YES

ty

[alpine sable]

I wonder why they're putting brackets randomly

[royal matrix]

and for this one

would it be

-21?

how about this one?

42?

please help

[alpine sable]

yes

[royal matrix]

YAY 100%

guys im learning more from you, then i am from my maths teacher

58.8 divided by 8

how do i do that

[vale wigeon]

do you know how to do long division in general

[royal matrix]

nope

[vale wigeon]

...might wanna learn that then

[royal matrix]

not in generl

general

I know how to do it

though

btw what is 11x2

[grim crag]

22

[royal matrix]

ty

[vale wigeon]

... gotta brush up on your multiplication too!

anyway

so you know how to do long division but you cannot do it on 58.8/8 specifically?

[royal matrix]

I only got 20% for my maths exam

[grim crag]

thats okay people learn in different ways and paces

[royal matrix]

or as americans say "math"

[royal matrix]

well i tried

thats what counts

[grim crag]

yeah :)

[royal matrix]

hmm

[vale wigeon]

the exact percentage you got in your exam does not really matter for our purposes

[royal matrix]

i say you do colum methos

[grim crag]

fr

[royal matrix]

methods

[vale wigeon]

in fact if your goal is to learn math then grade numbers should all be taken with a grain of salt

[royal matrix]

and then you remove the decimal point

then times it by 10 after your done

[vale wigeon]

almost. except at the end you divide by 10, not multiply.

[royal matrix]

oh yes

ill try on a piece of people and ask if i did it right

is it 7.35

[vale wigeon]

,calc 58.8/8

[ocean seal]

Result:

7.35

[vale wigeon]

checks out

[royal matrix]

you could have just done that??

,calc 3/5

[ocean seal]

Result:

0.6

[vale wigeon]

well i don't have any paper on me to do arithmetic by hand nor the desire to do it

[royal matrix]

,calc 2.4/8

[ocean seal]

Result:

0.3

[vale wigeon]

you on the other hand want to get your math up to speed

or so i gather

[royal matrix]

yes

[vale wigeon]

so i would recommend against using calculators of any kind too much (or at all, even)

[royal matrix]

well

i do struggle reading a bit aswell

[vale wigeon]

they are fine for checking your answers but you have to resist the temptation to throw the numbers in first

[royal matrix]

so i get the maths worded questions wrong

[royal matrix]

yes

what the actual f

I cant do this

[vale wigeon]

... this is not any kind of test or anything is it?

[royal matrix]

what do you mean

i actually got homework to do

[vale wigeon]

okay so this is homework

that's what i wanted to know

[royal matrix]

its just some work

nvm that has my teachers name on it forget that

[vale wigeon]

anyway, variables as a concept are a good bit more abstract than numbers

[royal matrix]

okey

[vale wigeon]

so if you struggled with numbers just now, i would not blame myself for struggling with a problem involving variables if i were you

[royal matrix]

i know how to do algebra

a bit

[vale wigeon]

if you have time, you might want to look at resources like khanacademy to practice stuff from the ground up

[royal matrix]

this is due tommorrow and its 9pm

:((

[vale wigeon]

this problem could have been phrased with a, b, c and d being just blank boxes in the table of values

would that make it easier for you?

[royal matrix]

hmm

[vale wigeon]

(would be less letters, for sure)

[royal matrix]

ok

quick question

am i allowed to post website links here because i think i found a website

[vale wigeon]

there is no rule against website links

[royal matrix]

is this legit

[vale wigeon]

yuck!

[royal matrix]

?

[vale wigeon]

don't use that or anything like it

[royal matrix]

is it fake

[vale wigeon]

doesn't matter

it'll actively harm your efforts to learn math

[royal matrix]

hmm

itdoesnt seemlegit

[vale wigeon]

and you should not use it even if is was legit

[royal matrix]

anyways ill listen to you, as you are more professional then a website

[alpine sable]

[royal matrix]

would a be -3

beacuse you do -3 x 2

which is -6

[vale wigeon]

yes

[royal matrix]

then you + 3 which is -3

[vale wigeon]

better to use an asterisk rather than the letter x for multiplication

but yes, 2*(-3) + 3 = -3

[royal matrix]

whats that

[royal matrix]

ohh

ok

this be 1?

[vale wigeon]

yes

[royal matrix]

yay i got them all right!

i just found out I am capable of doing this, its just lazyness

what did i get wrong

it says it is wrong

pls someone help

[vale wigeon]

a is wrong

everything else is ok

a = 2*(-3) + 2 = -4, not -2 as written

i'm gonna sleep now so if i don't respond that's why

[royal matrix]

ty for your help

<33

what are the answers for this one someone?

ANYONE

PLS

[hardy shell]

help, I did row 2 - 2*row1 which is correct but dont know what else to do

[hardy shell]

i did row3-3*row1 as well but apparently thats not right

[crimson totem]

i guess get common coeffecient of x in 1 an 2 then remove x by elimination and then get common coeffecient of x in 2 and 3 and then remove x by elimination

[hardy shell]

huh

how

[crimson totem]

multiply 1st equation by 2

and then subtract 2nd equation from the result

then
multiply 1st equation by 3 and subtract 3rd equation from the result

the 2 resultant equations will be in the form of linear equation in 2 variables

[hardy shell]

I see

.rcww

[alpine sable]

oh

[main kraken]

well

that’s (sqrt5)^3 / (sqrt4)^3 all right

but wait

do you know what a cube root is

[azure jungle]

How do I know what x will make the whole equation equal to 0?

[azure jungle]

example

f´´(x) = 3x^2 - 6/2x

that must be = 0

so:
f´´(x) = 3x^2 - 6/2x = 0
x=?

[boreal verge]

you solve it normally?

[outer lark]

6/(2x) ?

[azure jungle]

-6/2 (fraction) * x

[outer lark]

so 3x^2 -3x = 0?

[azure jungle]

or so, yeah

[outer lark]

quaaadratic formulaaa?

[azure jungle]

I just need it to be 0

how do I find that

[outer lark]

quadratic formula

[boreal verge]

or factor

[hollow sparrow]

3x² - 3x = 0 <=> 3x(x - 1) = 0
|| <=> x = 0 OR x - 1 = 0
<=> x = 0 OR x = 1||

[outer lark]

[azure jungle]

thankss

[hollow sparrow]

did you understand it ?

[azure jungle]

but

where did the -1 come from

is that the x

last one

[hollow sparrow]

if the multiplication of two numbers equal to 0 that means that at least one of them is equal to 0

since :
3x² - 3x = 3x(x - 1)

that means :
3x = 0 OR x-1 = 0

if one of them (x or x - 1 ) equal to zero then the whole equation will too

[azure jungle]

ye, but I can't just be putting 0's in every quadratic formula?

like

I have 7 numbers that all multiply

and every single one has an x

My solution would be, make the x = 0 and boom, everything is 0

[azure jungle]

or can I ?

I just tried brute force of logical numbers

and 1 works

x = 1

or x = 0

3x² - 3x = 0
3 * 1^2 - 3 * 1 = 0
OR
3 * 0^2 - 3 * 0 = 0

would both answers be considered correct?

can't be, cuz that x is my x-coordinates for my inflection point

😭

okay so, 0 is the correct one, x=1 is wrong

it is all wrong

[azure jungle]

okay look

I need to get these 2

And I don't know what to do

[hollow sparrow]

you found the value of x
which is x= 0 and x = 1

you need just to find the value of y

[azure jungle]

right now I have:
f(x) = 1/4 * x^4 - 1/2 * x^3 - 2
f´(x) = x^3 - 3/2 * x^2
f´´(x) = 3 * x^2 - 6/2 * x
f´´´(x) = 6x - 6/2

[azure jungle]

OOH

hold on

(" I looked in solutions to draw this graph")

but

because
X = 0 and x = 1 made the whole equation 0, they are the 0 points

okay

but now, to find y, I need to insert x=0 orx=1 in f(x) = 1/4 * x^4 - 1/2 * x^3 - 2

and that does not give me the solution

[hollow sparrow]

yes

[azure jungle]

nvm

I am tired man

I typed in the equation from a different task in my calculator

🤦‍♂️

It works

like 3 other ones I finished

...

thanks for helping

[quick pulsar]

If x^2 + xy +y^3 = 1, find the value of y''' at the point where x = 1

[quick pulsar]

So this problem is asking me to use implicit differentiation on this equation to find the point where x = 1. I can't seem to figure it out though as im confused on how to do triple implicit differentiation

Can someone walk me through the problem step by step

im currently stuck with dy/dx = -2x/(1+3y^2) and I dont how to approach from there

[last pond]

Proving angles 1,2,3, and 4 are all right angles. But using postulates, theorems, and definitions.

[last ether]

You can't assume right angles lol

[alpine sable]

^ Proof by picture is terrible way to proof.

[last pond]

"If two lines are perpendicular, then they meet to form 4 right angles"

it's asking me to prove this statement

[alpine sable]

How do you know they are perpendicular?

[last ether]

And how do you know they are perpendicular?

[last pond]

the question says it is

[alpine sable]

You have no information, no angles nothing.

[last ether]

That's crucial information if the problem gives you it

You didn't provide that

If that's the case, use the properties of perpendicular lines and vertical angles

[alpine sable]

Angles at a point equal 360 degrees

360 / 4 = 90

If they are perpendicular and they are meeting at a point then they must be at right angles to each other.

and according to vertically opposite property they intersect and if 1 side intersects at 90 degrees then the other must intersect at 90 degrees.

and according to angles on a straight line they must also equal 180 degrees

and therefore all angles must be at 90 degrees.

[young quest]

I have a question how do you solve this math equation? I understand semi partially but I am still confused.

[rose schooner]

so u want to isolate R

PV/nT = R

so let me spell this out

P * V = N * R * T

by dividing both side by N*T you can have one side with R isolated

@young quest does it make sense

[young quest]

I understand it a little bit but I still confused because it my first time learning about this math equation

[rose schooner]

i think thats teh pressure equation for chemistry

[rose schooner]

what are u confused about

which part

[young quest]

This part here

[rose schooner]

• = multiplying

P x V = N x R x T

same thing

[wary stream]

If you have 12 = 24R, do you know how to solve for R?

[gray isle]

where the equation is applied doesn't really affect what you'd do to isolate a variable here

[young quest]

I was looking the textbook example it had it flip in opposite direction would the answer be R = PV/nT? (but in a fraction form)

[gray isle]

()

[alpine sable]

Simple interest formula.

[gray isle]

R = PV/(nT)

Simple interest formula.
no

[alpine sable]

Oh gas law

Changing subjects.

[gray isle]

flip in opposite direction
poor description

best to describe actions as applying the same operation to both sides

[young quest]

I couldn't describe it well because I refencing the textbook example I didn't how to explain to you.

[gray isle]

no that makes no sense

because its really messed up and wrong

[young quest]

not really the last is not the correct answer to the math equation

[alpine sable]

Oops I just noticed.

[gray isle]

best to describe actions as applying the same operation to both sides
consider simpler equations
like
123x = 7
where to isolate/solve for x,
what you'd do would be best described as dividing both sides by 123

hi can someone help with this?

[valid lake]

2 < x < 4

[long spindle]

i know that to be speeding up, both acceleration and velocity need to be the same signs, but how do i find that on the graph?

[muted wigeon]

hello i am new to this server i really need help on this problem i really struggle with math : ( i started classes week ago i need help figuering out this question my professor gave us for extar credit

Find five consecutive integers such that:

“The sum of the first and 5 times the third is equal to 41 less than 3 times the sum of the second, fourth, and fifth.”

Make sure to list ALL five integers in your answer and show all of your work!

[steel tiger]

How do you find the level of signifiance within questions like these?

[gusty gorge]

compute the p-value

[merry depot]

Usually it’s 1 - (confidence interval size)

[gusty gorge]

check if it's < 0.01

[steel tiger]

Ah ty

So in this case it would be 1-0.99?

[gusty gorge]

yes it would be

[steel tiger]

Ah gotcha

Ty for the answer!

[wanton hatch]

[red vault]

how do i get help

[wheat isle]

you ask for help here

[sullen meteor]

Ye

[red vault]

ok so i jus ask me math question now

[sullen meteor]

Ye

[wheat isle]

yes

[red vault]

how do i find what percent of 18 is 12

[sullen meteor]

12/18*100

[red vault]

ok lets see

[sullen meteor]

Basically divide the number by the total

[red vault]

yay its right

[sullen meteor]

Nice

[red vault]

i gonna have to be up so long for math finals

[sullen meteor]

Good luck

[red vault]

thank u

[sullen meteor]

Don’t do what I did and bomb

[red vault]

i try

[sullen meteor]

Good luck and study hard

[red vault]

do u find helping other people with math fun

[strange meadow]

yes

[red vault]

how do i do this i already know the answer but not how to solve

[gusty gorge]

try multiplying both sides by x-6

alternatively, if you don't like fractions

raise both sides to the -1 power

to get (x-6)/x = 3

[strange meadow]

when a question asks you to solve for x and theres fractions

the best thing to do is get rid of all the fractions by cross multiplying

[red vault]

so would i do 3*x then get 3x

nvm i just got it

[strange meadow]

3x=x-6

you probably got it

[red vault]

ya then i subtracted the x from x-6 from 3x so i got 2x = -6 then dived and got x = -3

did i get this right

i know the first part is right because that is the 2 slope points

its just the = part

how do i find 3 consecutive integers whos sum is 171

[gusty gorge]

say N is the first integer

what are the next two in terms of N

can you write an equation for it

[fathom slate]

can someone help me with my hw

[gusty gorge]

probably but you need to make your own channel from the available channels

[red vault]

how do i do this one

im going to bed

[astral sedge]

Can someone please help me I do not understand how to do this. Thank you in advance.

[gusty gorge]

the corresponding angles in the figures are the same

you're given 3 of the angles

furthermore, you can use the fact that the angles inside a quadrilateral add up to 360 degrees

[astral sedge]

Oh I completely forgot about that thank you so much!

[wheat crystal]

problem #55

[alpine sable]

So, what have you tried

[wheat crystal]

so what u do on these problems

is split the denominators

so i got A/x + b/x^2 + c/x^2+3 + d/(x^2+3)^2

but apparently my numerator is wrong

like instead of C its Cx+d

and instead of D its Ex+f

is it because its a nonfactorable quadratic

Welp..

[spare plaza]

Teacher hinted that use distance formula

But i don't know how to do it

[vale wigeon]

is the 13 meant to be under the root or not?

[spare plaza]

Under prolly

[vale wigeon]

"prolly"

[spare plaza]

Well yes its under

[vale wigeon]

what comes to mind is x^4 + 5x^2 + 4 = x^4 + 4x^2 + 4 + x^2 = (x^2 + 1)^2 + x^2

so $\sqrt{(x^2+1)^2 + x^2}$ could be read as, say, the distance between $(x, x^2+1)$ and $(0,0)$

[ocean seal]

Ann

[spare plaza]

Oh ok thats good

Wait its (x^2+2)^2 ig

[vale wigeon]

yeah oops typo

the idea's still there tho

[spare plaza]

Ok ok

[vale wigeon]

something similar could likely be done with the other radical

[spare plaza]

Yup

Oh wow its done

[novel oar]

Hello can anyone help for 4th question

[novel oar]

i don't know what must i do lol

[mortal trellis]

IVT

[novel oar]

but we have no interval

When:

The curve is the function y = f(x),
which is continuous on the interval [a, b],
and w is a number between f(a) and f(b),
Then ...

... there must be at least one value c within [a, b] such that f(c) = w

[raven haven]

are you asking about q4

can you type it out please (LaTeX preferably)

[novel oar]

Proof that x*9+3x-1 has at least one solution.

[tacit arch]

This again probably

[raven haven]

[tacit arch]

You're supposed to find the endpoints

[mortal trellis]

choose a and b so that f(a) and f(b) have different signs

[novel oar]

i got it thanks all

[alpine sable]

i need help of some math of finding parallel or smthing

[alpine sable]

my teacher said, i gotta write these simple stuff to graduate, but the point is i dont even understand

[rocky grove]

Hmm

[alpine sable]

im fr dumb

[rocky grove]

Would you like to read about your lesson or are you more comfortable listening to a video?

[alpine sable]

i dont think i got time

gotta turn in in under 15 minute

._.

[rocky grove]

No you're not.

Okay I'll tell you a small hint

[alpine sable]

alr alr

thanks

[rocky grove]

Angles of the same color are the same

This is your hint

@alpine sable

[alpine sable]

thanks ima try to figure it out

[rocky grove]

[alpine sable]

nvm i give up

[rocky grove]

Okay so

As I showed you in the picture

The black angles are the same

And the red angles are the same

[rocky grove]

Let's go to page 1 and select the first question

It shows us 2 angles opposite to each other from the inside right?

[alpine sable]

its fine its fine, failing one subject wont hurt too much i guess

[rocky grove]

Hey no

[alpine sable]

i cant math

[rocky grove]

Don't have a mindset of this type

You can do this

Don't give up unless you tried all your efforts

[alpine sable]

A

[rocky grove]

Anyways

1st question

We have 2 angles opposite to each other

24x + 3 and 26x -3

Let's refer to what I sent

Looks like if 2 angles are opposite to each other from the inside, then they are the same

So

(24x+3) = (26x-3)

[alpine sable]

ohhhh

alr alr

ig ik how rn

[rocky grove]

Nice nice

Hope you get an A+ at least

[alpine sable]

thanks

[high ether]

how is this a homogenous differential equation?

[high ether]

shouldnt the second member be 0

unless idk what homogenous means

my book says it's homogenous

[rocky grove]

Try dividing by x

Also

Homogeneous diff equation is a differential equation where every term is a derivative of y, and where all the derivatives of y are raised to the first power

Like y' + y = 1 is a homogeneous function

While (y')^2 -2xy^2 = 15y is not

[red vault]

help please

[placid swallow]

open a new channel

I'll gladly help u

[red vault]

do i do that in #help-3

$F(x,y)=y'=\frac{1+xy}{x}$

[kindred anchor]

I don't think it's homogenous

Besides, My knowledge in DEs is a bit rusty smh

[woven jetty]

can someone help with 11 e pls

[placid swallow]

ye

[wind cloak]

Expand it all out

Then put it back together

Or there's another way I suppose

Not sure if it would work

[placid swallow]

exactly

[wind cloak]

You can use the difference of squares for the center

And then factor

[placid swallow]

just factor p^2 - q^2

[wind cloak]

Oh then it becomes a perfect square

[tulip egret]

pls someone help me solve radical equations in one variable. only 7 questions

[placid swallow]

send it

mind that solving radical equations means usually solving a system

[placid swallow]

which one do you wanna start with?

[tulip egret]

im not sure about 1 and 2

[placid swallow]

what have you done so far?

[tulip egret]

1 2 and 4

also 4 im not sure if its correct

[placid swallow]

show the 1st one

[tulip egret]

x=8

[placid swallow]

i mean the steps

[tulip egret]

i didnt solve it by my self

i used some apps but idk if its correct or no

[placid swallow]

is it (2x)^2/3 or just 2 * x^2/3

[tulip egret]

2x^(2/3)=8

[placid swallow]

nice

[tulip egret]

i wanted to do this one quick cuz i have another 7 HW

[placid swallow]

I wanna see your actual work

@tulip egret

and btw the answer is not 8

[tulip egret]

the steps and all of this?

[placid swallow]

yes

[tulip egret]

i didnt do it

[placid swallow]

well, do it

[tulip egret]

i dont know how

[placid swallow]

I'd start by writing the LHS in radical form

[tulip egret]

i want to finish it fast cuz i also have 7 hw left

[tulip egret]

idk what is that

i didnt understand anything from the first day

[placid swallow]

have you followed lectures?

Well, yeah, that might be an issue.

[tulip egret]

yes

[placid swallow]

what does it mean ^2/3

[tulip egret]

and ig they gave us that yesterday

[tulip egret]

the power

[placid swallow]

you can express that in radicals

[placid swallow]

yeah

also, it's (2x)^2/3

[tulip egret]

idk the teacher wrote it this way

[placid swallow]

isolate the x

First

[tulip egret]

can u solve it for me pls

[placid swallow]

you will learn absolutely nothing if I do that

[tulip egret]

i will study later

rn i have to submit 8 hw

[placid swallow]

that equation is quite easy

I'm pretty sure you can do it

[tulip egret]

i dont even remember what we took at school

if i remember i will solve it by my self

im also rn solving biology hw

[pallid igloo]

me and my classmates have been struggling on this problem, can anyone please explain this carefully?

[hard patio]

well first off the figure is slightly misleading

[pallid igloo]

i know right

[hard patio]

ye lol

[pallid igloo]

but is there like a way to solve this w/o the figure?

[hard patio]

so start off with GA = SN

[pallid igloo]

mhmhm i already wrote that down :D

[hard patio]

subtract IA from both sides

[hard patio]

XD

[pallid igloo]

wait what-

[hard patio]

mind telling me what else youve worked on

[pallid igloo]

what i wrote is just the given lol

GA = NS, given

IA = TS, given

thats it :))

[hard patio]

:))

okay so

GA = NS

[pallid igloo]

what next?

[hard patio]

subtract IA from both sides, so you get GA- IA = NS - IA

right?

[pallid igloo]

yes yes

subtraction property is the reasoning?

[hard patio]

now IA=TS

[pallid igloo]

ahh i see but i also need the reasons though :))

[thorny root]

reasons are rather for the conclusions you have come to along your proof not really why did you make a step

[hard patio]

if you know the working

and understand it

[pallid igloo]

i dont really know the teacher just makes us do steps for some reason

[hard patio]

you can come up with it easily

[pallid igloo]

ahh alr

lets go back to what you were saying then thanks

[hard patio]

where?

[pallid igloo]

here

[hard patio]

so GA - IA = NS- TS

what atre those now

[pallid igloo]

hm

[hard patio]

now, look at the figure

[thorny root]

yes, there is a one more "pseudo-given" which stems directly from the diagram

and ultimately helps you solve it

[pallid igloo]

i dont get it 😭

[thorny root]

it's really straightforward

so straightforward that you may overlook it many times

or ignore

[hard patio]

look at the figure, and see what both sides of the equation mean in the diagram

[pallid igloo]

idk but the lines are not equal

[thorny root]

tell me

what does GI + IA equal to

[pallid igloo]

st + tn?

[thorny root]

sure but that's leaping over a step

or two

[pallid igloo]

oh then im kinda stumped 😭

[thorny root]

GI + IA is equal to the line GA

[pallid igloo]

o

[thorny root]

that's all you need to notice

and ST + TN is equal to the line SN

[thorny root]

so when you return to this equation

[pallid igloo]

so line segment ga = line segment sn?

[thorny root]

that's given, yes

[pallid igloo]

o right aaaaaaaaa

[thorny root]

you just need to decompose the lines GA and NS in that equation

[pallid igloo]

i see that its equal now

[thorny root]

sure

[pallid igloo]

decompose in this equation?

[thorny root]

kinda?

decompose the lines AG and NS

[pallid igloo]

so

GA + IA - IA = ST + TN - TS

???

[thorny root]

yup

that's the final step

[pallid igloo]

wait thats all?

[thorny root]

yes just simplify the equation by cancelling out the terms

[pallid igloo]

GA = TN

[thorny root]

GI*

you had a typo

[pallid igloo]

OHHHHHHHH

i was following his equation aaa

[thorny root]

you got it

[pallid igloo]

i feel a lot better now thanks :))

yess

thank you man

[ruby bison]

does a neither function have an inverse?

[vale wigeon]

wdym by "a neither function"

do you mean a neither-even-nor-odd function?

[ruby bison]

yes

[vale wigeon]

if so then you can't tell from that info alone. there exist functions which are neither-even-nor-odd and have an inverse, and there also exist ones that don't.

[ruby bison]

well i need to explain that x2-4x+9 does not have an inverse

idk how i would do that

[vale wigeon]

did you mean x^2 - 4x + 9?

[ruby bison]

i cant use the hor. line this

test

[ruby bison]

yes

[vale wigeon]

so you are disallowed from pointing out that, say, f(0) = f(4) and so the function is not one to one and hence not invertible...?

[ruby bison]

wdym?

[ruby bison]

yea im able to explain like that

[vale wigeon]

you say you "can't use the horizontal line test"

[keen mason]

Can u not just says its a many to one function?

[vale wigeon]

so clearly you have some special instructions

about what kind of argument is allowed and what isn't

is that so?

[ruby bison]

basically

prove the function does not have an inverse function

with using the hor. line test

so basically not using a graph and just algebraically

[keen mason]

???

[vale wigeon]

...

[keen mason]

but u said with using the hoz line test?

[vale wigeon]

@ruby bison show us a picture of the problem statement

[vale wigeon]

right

[ruby bison]

wait

without

sorry

my bad

[keen mason]

Xd

u have f(x)

get f^-1(x)

[vale wigeon]

so then pointing out that p(0) = p(4) would not be in violation of this instruction.

it's called p, not f.

[ruby bison]

i dont get

[keen mason]

put 4 as x into the equation

and put x and 0 into the equation also

[ruby bison]

where di 4 come from

[vale wigeon]

do you mean "i don't understand what you are saying" or "i understand what you are saying but not how you came up with it"

[ruby bison]

i understand what u are saying

just idk where 4 came from

[vale wigeon]

p(x) = x(x-4) + 9

[ruby bison]

and why i need to sub in 0

[vale wigeon]

x(x-4) has two obvious roots at 0 and 4, thus your function will have the same value (9 in this case) at both said roots

[ruby bison]

oh so basically

i can say that

its a many to one function because

the two roots both have the same y value?

hence the many to one

[vale wigeon]

you're trying to look for something sophisticated in this

don't

i mean sure you can call it a many-to-one function if you want

if thats what your teacher wants from you

[ruby bison]

he just wants me to prove

it does not have an inverse

so if its many to one means it does not have inverse cus inverse can happen when only one to one

[keen mason]

Basically

if you try to get the inverse of that function

you would end up with 2 functions, coz its kinda not possilbe

[ruby bison]

ok

so i can explain like i did above right

both roots have same y value

so its many to one

[keen mason]

U could its probably not enough, give the example ann give along with it

[ruby bison]

hence no inverse

[keen mason]

Yea

[ruby bison]

thank you

the first screenshot is me trying to show the common difference is 9

for some reason i keep getting the wrong answer and i cant see what is wrong with how i am trying to find d

i am using the formula for arithmetic series

for both the fifth and twentieth term and then i am trying to find d using simultaneous equations

i really dont know what is wrong with how im trying to approach this

[alpine sable]

an = a1 + (n – 1)d is arithmetic sequence formula

[cold zenith]

but its a series

[delicate jacinth]

46 = a_1+4r
181 = a_1+19r
181-46 = 15r
r = 9

[vale wigeon]

@cold zenith it says the 5th TERM is 46, not that the SUM OF THE FIRST 5 TERMS is 46.

you either misread or misinterpreted the problem

[cold zenith]

but isnt the fifth term in a series the sum of the first 5 terms of a sequence?

[vale wigeon]

no

[cold zenith]

lol

[vale wigeon]

you are confusing terms with partial sums

[cold zenith]

i thought a series was a sum of terms in a sequence

[vale wigeon]

in all honesty, the way this problem uses the word "series" feels like a misuse of terminology to me.

but they would not write "fifth term" to mean "fifth partial sum", that's for sure.

[cold zenith]

am i right in thinking that series cant have common differences because each term gets increasingly bigger or smaller?

so when it says common difference it must be for a sequence?

[vale wigeon]

you're kind of right but also kind of not and it's hard to say exactly what is wrong

[cold zenith]

ok so i would just use the formula for sequences here?

[vale wigeon]

the what

[cold zenith]

a + (n-1)d

instead of the formula for series

[vale wigeon]

you were taught that as "the formula for sequences"?

yikes

that's the n'th term of an arithmetic sequence, surely...

[cold zenith]

thats what i mean

Un = a + (n-1)d
