I need help making my sign chart

#

I don't understand why I can't make it proper

#

My teacher said it's negative from (-infity, -1) U (1/2, + infinity) and positive from (-1,1/2)

#

Appreciate some help on this

for 3c

#

This is whwt i have so far

#

How do i continue?

oak slate
#

divide everything by 3 to simplify then find the answer by plugging in some values

drifting root
#

Is there a better way than guess and check or nah

icy adder
#

you can try solving the summation

drifting root
#

Idk how to deal with that tho

icy adder
#

do you know the summation of first n natural numbers

drifting root
#

Uhhh

#

Probably not?

icy adder
#

can you find sum of an AP

#

whose common difference is 1

#

and starting term is also 1

drifting root
#

n/2(1+n)

icy adder
#

yeahh n x n+1 / 2

#

that is the sum of first n natural numbers right

#

the sum of series of 1+2+3+4+5....+n

drifting root
#

Ye

icy adder
#

you need to solve both the summation using formulas

#

the first summation is sum of a GP

#

the second summation is the sum of an AP

#

try solving those

drifting root
icy adder
#

yeahh correct sorry mb

#

uhh now you have to do hit and trial

#

try putting values of n like 1 2 3 4

#

thats the only possible way afaik

very random equations

viral dagger
#

ikr

tawdry laurel
#

i've seen ppl use vietas on this stuff b4

viral dagger
#

how tf do you use vieta on this

tawdry laurel
#

let a, b, c be roots of a cubic equation

#

nvm

merry pewter
#

the sqrt(3) makes me think we should replace b with sqrt(3)b

#

so that the b^2/3 becomes b^2

#

then i think it will have something to do with (a+b+c)^2

viral dagger
merry pewter
#

to make the equations nicer

viral dagger
#

ohh

#

gimme a sec

merry pewter
#

jesus christ

#

ill do it,
$$a^2+\sqrt{3}ab+b^2=25$$
$$b^2+c^2=9$$
$$c^2+ca+a^2=16$$
$$\sqrt{3}ab+2\sqrt{3}bc+3ac=m\sqrt{3}$$

i guess the thing to notice is that the right side is all perfect squares

uhhhh

#

oh yea

merry pewter
#

i thought it was going to be the factorization of a^3+b^3+c^3-3abc but now i don't think so

crude jungle

#

yeah ikik

crude jungle
#

smth we can use it

#

uh

tawdry laurel
#

i just didnt see it when i first looked at qn

viral dagger
#

$$a^2+\sqrt{3}ab+b^2=a^2+b^2+c^2+c^2+ac$$
$$\sqrt{3}ab=ac+2c^2$$

grand pondBOT
#

Skill_Issue (ping when u respond

crude jungle
#

ok i think i got smth

#

so first of all

#

we can get c^2 = 9 - b^2 from eq 2

#

and substitute in eq 3

#

and uh, after simplifying, im getting

#

$$ca+a^2-b^2=7$$

grand pondBOT
#

Baizhi

crude jungle
#

from eq 1, we get

#

$$b^2 = 25 - a^2 - \sqrt{3}ab$$

grand pondBOT
#

Baizhi

crude jungle
crude jungle
#

by which we will get

#

$$ca + 2a^2 + \sqrt{3}ab = 32$$

grand pondBOT
#

Baizhi

crude jungle
#

now rearrange eq 1 by shifting all terms to RHS except root 3ab

#

$$\sqrt{3} ab = 25 - a^2 - b^2$$

grand pondBOT
#

Baizhi

crude jungle
#

...

#

ok i messed up ;-;

midnight plankBOT

@viral dagger Has your question been resolved?

midnight plankBOT
#

@viral dagger Has your question been resolved?

graceful drum
#

wait

#

does this work

#

let x = b/sqrt(3)

#

then for the first equation

#

a^2 + x^2 + sqrt(3)ax = 25

#

for the second one x^2 + c^2 = 9

viral dagger
#

the same

graceful drum
#

ok but i found something with a similar substitution

#

for the 3rd one c^2 + a^2 + ac = 16

#

rewritten as (c-a)^2 + 3ac = 16

#

we now that 25 - 16 - 9 = 0

#

therefore (a^2+ x^2) - (x^2 + c^2) - (c-a)^2 + sqrt(3)ax - 3ac = 0

#

or (a^2 + x^2) + sqrt(3)ax - 3ac = (x^2 + c^2) + (c-a)^2

#

this implies that (a^2 + x^2) + sqrt(3)ax - 3ac >= 0

#

therefore 25 - 3ac >= 0

#

therefore 3ac <= 25

#

Thats the first part

#

next

viral dagger
graceful drum
#

cus sums of squares of real numbers are always postiive

viral dagger
#

its (x^2+c^2)-(c-a)^2 thats not sum of squares

graceful drum
graceful drum
#

now we know that 9 + 16 = 25

#

therefore (x-c)^2 + (a-c)^2 + 2xc + 3ac = 25

#

or 25 - 2xc - 3ac = (x-c)^2 + (a-c)^2

#

therefore 25 - 2xc - 3ac >= 0

#

or 25 - 2xc >= 3ac

#

but we know 25 >= 3ac

#

therefore -2xc >= 0

viral dagger
#

contradiction then?

graceful drum
#

no

#

then 2xc <=0

viral dagger
#

a,x,c are positive reals

graceful drum
#

is zero positive?

#

then i made a mistake probably

viral dagger
#

i dont think so?

graceful drum
#

can u even add inequalities together

upper crag
#

0 is not positive or negative

feral sedge
#

0 is 0

graceful drum
#

but ig it has something to do with inequalities

graceful drum
#

u cant add inequalities like that

#

rather we can

#

but the application here is wrong

midnight plankBOT
#

@viral dagger Has your question been resolved?

feral sedge
#

a^2 + ab + b^2 / 3 = 25
b^2 / 3 + c^2 = 9
c^2 + ca + a^2 = 16

from equation 1 = equation 2 + equation 3, derive this: ab - ac - 2c^2 = 0. continue,
substitute a = tc into ab - ac - 2c^2 = 0 to get b = c(1 + 2/t)
substitute b = c(1 + 2/t) into equation 2 to get c^2 = 27t^2 / 4(1 + t + t^2)
substitute a = tc into equation 3 to get c^2 = 16 / (1 + t + t^2)
hence, t = a/c = 8sqrt3 / 9, or a = (8sqrt3)c / 9
substitute t = 8sqrt3 / 9 into b = c(1 + 2/t) to get b = (3sqrt3 + 4)c / 4
substitute b = (3sqrt3 + 4)c / 4 into equation 2 to get c^2 = 432(91 - 24sqrt3) / 6553
substitute a = (8sqrt3)c / 9 and b = (3sqrt3 + 4)c / 4 into ab + 2bc + 3ac to get (72 + 91sqrt3)c^2 / 18
substitute c^2 = 432(91 - 24sqrt3) / 6553 into (72 + 91sqrt3)c^2 / 18 to get 24sqrt3
hence, m = 24

(i cannot find a nice way to do this)

#

the values of a, b, c (which happen to unique) are not nice either

#

$(a, b, c) = \left(32\sqrt{\frac{91 - 24\sqrt{3}}{6553}}, 36\sqrt{\frac{\frac{2185}{48} + 24\sqrt{3}}{6553}}, 12\sqrt{3}\sqrt{\frac{91 - 24\sqrt{3}}{6553}}\right)$

how did you get that

cunning dragon
# viral dagger how did you get that

bro first take express b^2 from second equation and then substitute into first equation you will get 16 and then and get c^2 which equals a^2 + ab - 16 and substitute it in 3rd equation and u get 2a^2 + ab +ca = 32 and when you get b^2 express it as c^2 and then we solve 2a^2 + ab +ca = 32 and c^2 = a^2 + ab - 16 and use c^2 from c^2 = a^2 + ab - 16 and take a=4, b= 3, c=1 as it is complex to me and solve ab + 2bc +3ac = 30 = m(3^1/2)

m= 10*(3^1/2)

lol i had done mistake m doesnt equals to 16 but equals to 10*(3^1/2)

#

@viral dagger yoo i had solved

viral dagger
#

erm

#

lemme repost

cunning dragon
#

is my answer correct

viral dagger
#

what do you mean "when you get b^2 express it as c^2 then ..."

viral dagger

oh thats what you meant

why a=4 b=3 c=1

then uhh idk

sinful trout

???

cunning dragon

it seems like if i sub its going in circles

sinful trout
#

a(a+b) = 16

viral dagger
#

huh

sinful trout
#

oops nvm

cunning dragon
sinful trout
#

$$\frac{b^2}{3} = 9 - c^2\to\frac{b^2}{3} + 7= 16 - c^2$$
$$16 - c^2 = ac + a^2 = \frac{b^2}{3} + 7$$
$$a^2 + ab + \frac{b^2}{3} = 25\to a^2 + ab+\frac{b^2}{3} + 7 = 32\to 2a^2 + ab + ac = 32$$

is what i have on hand

i had a(2a+b+c) = 32

#

and from the third one we have 2c^2 + 2ac + 2a^2 = 32

#

so 2a^2 + ab + ac = 2a^2 + 2ac + 2c^2

#

therefore, 2c^2 + ac = ab

the thing is all this time bc has not showed up at all

sinful trout
#

ikr

#

it's so annoying

#

maybe just multiply stuff randomly with b or c lmao

#

$$a^2c + abc + \frac{b^2c}{3} = 25c$$
$$a^2b + abc + bc^2 = 16b$$

#

does that help in any way

what if you square everything

ok this is starting to borderline joke

where'd the sqrt three come from what

this but replaced the x with b

don't

do that

Let ${a}$ be a real number and ${p(x)}$ be a polynomial such that ${p(a) \neq 0}$. If ${q(x)= (x-a)^np(x)}$ for each and every positive integer ${m \leq n}$, there is a polynomial ${p_m(n)}$ such that
[ q^{(m)}(x) = (x-a)^{n-m} \left( (x-a)p_m + \frac{n!}{(n-m)!p(x)} \right) ]

I found this from a solution from a high school math competition that I took two days ago. Idk where this is taken from or is there a name for this and where else I can apply this in the future.

How does one perform well on all math topics? What do these people have in common to be able to know tips and tricks and everything? Like I can do calculus but I can’t even do geometry.

Is there like a thing u should know that underlies all the math topics?

hey there

midnight plankBOT
lusty pike
#

I have the answer to this question but I don't know why it worked

#

the matrice P is part of an earlier question

#

and so by multiplying 24 by the determinate of P you get $\frac{24}{5}$

grand pondBOT
#

lusty pike

which is the answer

#

but why does that work?

flint anchor
#

find v.a and h.a

midnight plankBOT
flint anchor
#

h.a doesnt exist

#

and i have found the v.a but it is wrong

untold fern
#

you have factored correctly right? one sec ill do it

flint anchor
#

i found v.a with the help of the discriminant

flint anchor
#

but you will get 1 and 5

ripe gulch
#

-1

flint anchor
#

thing is 1 isnt included

#

only 5

flint anchor
ripe gulch
#

Nevermind u right

untold fern
#

so its just 1

#

yea

#

wait mb I tweaked

#

5

flint anchor
#

so why not 1

untold fern
#

at x = 5, there should be a VA

untold fern
#

with the numerator

#

if you factor the top, you get x(x+1)(x-1)

#

the bottom you get (x-1)(x-5)

#

therefore, the x-1 cancels and creates a hole

flint anchor
#

ohhh but when doing it with discriminant u wont be able to find it

untold fern
#

im not quite sure i understand

flint anchor
#

you know you could find the v.a with discriminant right?

untold fern
#

discriminant? of what

flint anchor
#

discriminant of denominator

oak slate
#

isnt that a matrix thing

flint anchor
#

how?

#

factorising i guess is more precise

untold fern
#

yeaaa I guess you can

#

but it can be inaccurate

flint anchor
untold fern
#

because if you plug in the answer it will cancel the top and it would be irrelevant

#

in the future, I would avoid using discriminant

#

stick with just factor and standard

flint anchor
#

ohhhh i guess you could always plug in the x's and see if it makes sense in the function

#

alright that was it thanks

What power makes it equal to zero?

midnight plankBOT
rose trout
#

None

vagrant mica
#

wait whatt

#

what do I put for my answer then?

keen herald
#

Any you've tried?

vagrant mica
#

It's not possible though

#

right

keen herald
#

It's not

#

Just trying to reinforce the idea lol

#

One might assume 1 or 0 would elicit silly behavior like that, but 36^1 is 36, and 36^0 is 1

last slate
#

^

#

LOL

vagrant mica
#

and it wasnt 0

last slate
#

x does not exist

last slate
#

Actually said what I was thinking but it’s not possible as n^0 =1

last slate
#

or DNE

vagrant mica
#

Imma just put no solution

keen herald
#

If you want something more rigorous, we can try taking the natural log of both sides

keen herald
#

$ln(36^x) = x, ln(0) = \text{DNE}$

grand pondBOT
#

m. frost

keen herald
#

It's the opposite of exponents, basically the function that gets the X in 36^x

last slate
#

Well ln(0) is undf btw

vagrant mica
#

Thanks guys

keen herald
#

But ln(0) is undefined so a^x = 0 can't exist

last slate
#

So technically even if you performed the nat. Log you would get DNE

How come 19 is a relatively simple antiderivative?

#

But why is this asking me for finding the n on the selected interval?

elder zephyr
#

it is not asking you to find n, but just saying that the integration constant depends of n

obtuse willow
#

I don't get it.

#

Why is it for 21 and 23 but not 19?

midnight plankBOT
#

@obtuse willow Has your question been resolved?

@obtuse willow Has your question been resolved?

brazen moth
#

Hi @obtuse willow

obtuse willow
#

Hello!

brazen moth
#

What you need to observe here is that at npi + pi/2

#

Tan and sec is undefined

#

That's why they have open brackets on such numbers

#

At these number that anti derivative and for this case the derivative will also go undefined

#

So they have excluded

brazen moth
#

Even if they wrote this

#

This would be fine too

#

Hope this helps

obtuse willow
#

So whenever I have an anti derivative that includes tan or sec.

obtuse willow
brazen moth
#

Yup

#

Any function including tan or sec

#

Also for csc and cot

brazen moth
#

This has to taken into account

obtuse willow
#

I see.

#

But sin and cosine don’t need that right?

obtuse willow
#

Why doesn’t it include the pik thing @brazen moth?

brazen moth
#

Yup

obtuse willow
obtuse willow
brazen moth
#

For that I have genuinely no idea

#

Maybe they forgot or something

#

But 19 will undefined at the same points aswell

#

See it's simple logic

#

Tan is sin / cos

#

Sec is 1/cos

#

Where cos goes to 0

#

Tan and sec get undefined

obtuse willow
#

Okay.

brazen moth
#

And that occurs at npi + pi/2

#

So we excluded those points

#

Similarly for csc and cot

#

Sin and cos themselves are always defined

#

They got nothing in the denominators to make them undefined

#

That's all

#

Do you get it now @obtuse willow

#

?

obtuse willow
#

Yes.

#

Hmm…

#

Question.

brazen moth
#

Yeah sure

obtuse willow
#

Since Sec is 1/Cos?

brazen moth
#

Can you please try and specify what you mean by balancing

#

@obtuse willow

obtuse willow
#

Oh.

#

I dunno how to describe it.

#

But could it be possible that the one Cos lets Sec be defined somehow?

brazen moth
#

Are you trying to say that does cos fill spaces sec doesn't and vice versa?

#

I Mean Thiers a lot of cool things about it

#

That I have stumbled upon while learning trigonometry

#

Give me a moment I will draw out some of them

obtuse willow
#

But it ain’t it?

#

Should I ask my teacher this tomorrow?

brazen moth
#

I Mean I will try to give you something to work with

#

Like look at this

brazen moth
#

Sec covers parts of the graph

#

That cos can't

#

And it's true the other way around

obtuse willow
#

I see.

brazen moth
#

Another one is that principle brach of cos graph

#

And sec graph

#

Fit perfectly

#

Together

#

Honestly one of the beautiful things I have seen

#

A graph do

low hull
#

Very

brazen moth
#

Cos x^2 and secx ^2

#

They fill each other out

#

To perfection

#

Covering all of infinity

low hull
#

The reason why i love math

brazen moth
#

Anyways @obtuse willow

#

I hope that's enough to satisfy your questions needs

polar socket
daring bison
#

when it goes up its increasing

#

when it goes down its decreasing

polar socket
cosmic tiger
#

so were lookign at both axis or...

polar socket
#

idk wym by axis, u just look at the slope

#

rise over run

cosmic tiger
polar socket
cosmic tiger
#

is the first one like...-2.5

polar socket
#

u dont have to determine the exact slope, u just have to identify if the slope is negative or positive

cosmic tiger
#

ermmm

#

negative..

#

i think

polar socket
#

okay negative

#

from where to where tho

cosmic tiger
#

yaaaaaaaaaaay

#

i-

#

uhm

#

i just look at the arrows...

polar socket
#

the x values, x-axis

#

is that what u meant earlier

cosmic tiger
#

yaaaaa

polar socket
#

aurrrr

cosmic tiger
#

my eyes arent really all that good but ill tryy

polar socket
#

u look at the x-values or x-axis to determine the intervals

polar socket
#

unless if u estimate like

#

234892 when the x-value is 4

#

then ill be like sideeying hardcore

cosmic tiger
#

i-

#

cry

#

is it the same -2.5

#

and uhm

#

omy

#

i think im stuck

polar socket
#

what

#

why is it -2.5

cosmic tiger
#

im not suree

#

i saw it kinda cuts thru

#

im not suree

polar socket
#

are u looking between -2 and -1 or smth

cosmic tiger
#

uh huh

polar socket
#

oh

#

gurl thats -1.5

cosmic tiger
#

or its -3

#

...

polar socket
#

okay let’s

#

divide this function into different sections

#

so it’s easier to visualize

cosmic tiger
#

oki

polar socket
cosmic tiger
#

ahhh i thought as muchh

polar socket
#

the function is divided into 3 sections, cut twice

#

bc u can see there’s a hill and a trough right??

#

1 hill, 1 trough

#

or trench

cosmic tiger
#

uh huhhh

polar socket
#

or whatever u wanna call the lowest point is

#

okay SO

brazen moth
cosmic tiger
#

is it like the minimum and maximum thingy...

polar socket
#

so yk this is negative right

polar socket
#

honestly I blocked that out bc of physics trauma

brazen moth
#

Yeah the bottom things

brazen moth
#

Ik you thinking about wavelengths

polar socket
#

censor it for me 🥰🥰

#

w*v#l#ngths

polar socket
cosmic tiger
#

yaaaaa

polar socket
#

u just need to figure out the interval part

#

or the domain

#

or the x-values

cosmic tiger
#

-1.5, 2

polar socket
cosmic tiger
#

waaaaa

polar socket
#

that’s the increasing part

cosmic tiger
#

omg...

polar socket
#

look at the first section of the graph

#

ur almost there gurlie

#

if u can get the increasing part

#

u can get the decreasing parts

#

PLURAL

cosmic tiger
#

-3...

#

idkkk

polar socket
#

oh gurl

polar socket
cosmic tiger
#

o

#

infinity..

#

idkkk

#

neg and positive

#

wait

polar socket
cosmic tiger
#

isnr both negative...

polar socket
#

what infinity

cosmic tiger
#

pos

polar socket
#

awm

#

positive infinity??

cosmic tiger
#

no neggg

polar socket
#

yas queen

#

bc we’re on the negative side of the x axis

cosmic tiger
#

its on the negative sideee

polar socket
#

so u found a part of one interval

#

-infinity

#

so the function is decreasing from negative infinity to what

cosmic tiger
#

pos infinity...

#

nooo

#

but its going down

polar socket
cosmic tiger
#

the other arrow

#

wait nu

polar socket
#

look where is it cut off

cosmic tiger
#

o#

polar socket
#

you already figured out the function is increasing (-1.5, 2) right

cosmic tiger
#

the intervals

polar socket
#

so where’s it’s decreasing

cosmic tiger
#

-1.5

polar socket
#

YASSS

#

(-infinity, 1.5)

#

OKAYYYY

#

THATS ONE OF THE DECREASING INTERVALS

#

there’s still one more

cosmic tiger
#

do we use union

#

or..

polar socket
#

always union

#

unless the problem uses the word “or” always use union

cosmic tiger
#

2ohhh

#

ohhh

#

so after union is

#

2

#

sorry bracket 2

polar socket
#

bracket??

#

wait

#

r u Canadian or American

#

or non American

cosmic tiger
#

(2

polar socket
#

okay

cosmic tiger
#

neither

polar socket
#

(2,

#

2 to what

cosmic tiger
#

im from pluto

#

uhm

#

infinity

polar socket
#

YASSSSSSS

brazen moth
#

🎊 🥳

cosmic tiger
#

yaaaaaaaaaaay

polar socket
cosmic tiger
polar socket
cosmic tiger
#

uhmm

#

i did

brazen moth
#

Go on.....

cosmic tiger
#

(-infinity,1)

brazen moth
#

Good start

polar socket
#

yas

cosmic tiger
#

union

polar socket
#

uh huh

cosmic tiger
#

(4,positive infinity)

brazen moth
#

It was going so well

cosmic tiger
#

uhh

#

uhm

#

two arrows

polar socket
brazen moth
#

4 arrows

cosmic tiger
#

ye 4

cosmic tiger
#

cant remember

#

is it like the or thingy

polar socket
#

THE FUNCTION??

cosmic tiger
#

ian know

cosmic tiger
#

ohhh

brazen moth
#

The function go up then down then up then down

#

It go up from
(-infinity, 1] U (3,4]

cosmic tiger
#

3,,,

#

how comes

brazen moth
#

And go down from
(1,3)U(4,infinity

cosmic tiger
#

oh

brazen moth
#

Is the function not approaching -infinity at 3

cosmic tiger
#

maybe i have eye problem so i can barely see

brazen moth
#

I think @polar socket has just left

brazen moth
#

You new to this

#

Jokes aside

#

It takes everyone time

#

So nothing to be embarrassed about

cosmic tiger
#

oki oki thanks for the help
