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
If you can ping me tho

divide everything by 3 to simplify then find the answer by plugging in some values
Is there a better way than guess and check or nah
you can try solving the summation
Idk how to deal with that tho
do you know the summation of first n natural numbers
n/2(1+n)
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
Ye
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
? Wont i just get what i did here
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

status 1
very random equations
ikr
i've seen ppl use vietas on this stuff b4
how tf do you use vieta on this
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
why can we do that
well b is real right? im just saying to replace it with a different variable scaled by sqrt(3)
to make the equations nicer
jesus christ
ill do it,
$$a^2+\sqrt{3}ab+b^2=25$$
$$b^2+c^2=9$$
$$c^2+ca+a^2=16$$
$$\sqrt{3}ab+2\sqrt{3}bc+3ac=m\sqrt{3}$$
Bair
D: what did i doo
hard to read 
$$a^2+\sqrt{3}ab+b^2=25$$
$$b^2+c^2=9$$
$$c^2+ca+a^2=16$$
$$ab+2bc+\sqrt{3}ac=m$$
Skill_Issue (ping when u respond
oh
wait no
i guess the thing to notice is that the right side is all perfect squares
i thought it was going to be the factorization of a^3+b^3+c^3-3abc but now i don't think so
i didnt see that
RHS got all perfect squares
yeah ikik
i just didnt see it when i first looked at qn
$$a^2+\sqrt{3}ab+b^2=a^2+b^2+c^2+c^2+ac$$
$$\sqrt{3}ab=ac+2c^2$$
Skill_Issue (ping when u respond
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
$$ca+a^2-b^2=7$$
Baizhi
Baizhi
put this
in this
by which we will get
$$ca + 2a^2 + \sqrt{3}ab = 32$$
Baizhi
now rearrange eq 1 by shifting all terms to RHS except root 3ab
$$\sqrt{3} ab = 25 - a^2 - b^2$$
Baizhi
@viral dagger Has your question been resolved?
@viral dagger Has your question been resolved?
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
this you subtitute b=sqrt3b
the same
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
how does it imply that
cus sums of squares of real numbers are always postiive
its (x^2+c^2)-(c-a)^2 thats not sum of squares
now we rewrite this as (x-c)^2 + 2xc = 9
mb both are positive, ill edit that
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
contradiction then?
a,x,c are positive reals
i dont think so?
can u even add inequalities together
0 is not positive or negative
0 is 0
but ig it has something to do with inequalities
this step is wrong though
u cant add inequalities like that
rather we can
but the application here is wrong
@viral dagger Has your question been resolved?
where is this q from lol...
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
$(a, b, c) = \left(32\sqrt{\frac{91 - 24\sqrt{3}}{6553}}, 36\sqrt{\frac{\frac{2185}{48} + 24\sqrt{3}}{6553}}, 12\sqrt{3}\sqrt{\frac{91 - 24\sqrt{3}}{6553}}\right)$
Mqnic_
my teacher posted it on their story and i just took it :p
:/
cmon free question that i found cant blame me
then ig. there is no reason to assume this question has a clean solution. if that is where it came from
it is cursed
spooooooky
alr im gonna open this till night if its not solved (hopefully elegant in the slightest) ill close this
maybe ill ask on mathexchange or smth
well there is a solution here. but it is not nice is all
i had to solve first but it seems to be easy ig
what?
yupp m=16 ig from my step
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
is my answer correct
what do you mean "when you get b^2 express it as c^2 then ..."
idk
bro u get b^2= 27-3(c^2) u have to express it in c^2
yupp and u know this gave me the idea to finding a general way to solve these types of equations and i m 13 yrs old kid and i will research on this thhing
this sesms like a random choice?
bro u have to first getting all the value of a and b and c by solve 2a^2 + ab +ca = 32 and c^2 = a^2 + ab - 16
quite literally (4,3,1) does not work
you get
ohh so i have to do more work on it
btw where u get this question
😭
@viral dagger where u get this question
it seems like mathematical analysis
@viral dagger what r u expecting from a 13 yrs old kid
nothing?
"skissue?" 
no offense :p
ooh
short for skill issue :p
but it seems like mathematical analysis
yeah ik
probably isn't
and "mathematical analysis" isn't very specific?
there are several fields of analysis
my friend calls me it so i just changed to it so i can shorten my name
what subs have you tried so far
b=sqrt3b to simplify to this
then uhh idk
???
systems of nonlinear equations ig
a(a+b) = 16
huh
well we aren't exactly going to be using algebraic geometry here are we
oops nvm
but it like university levels questions
$$\frac{b^2}{3} = 9 - c^2\to\frac{b^2}{3} + 7= 16 - c^2$$
$$16 - c^2 = ac + a^2 = \frac{b^2}{3} + 7$$
$$a^2 + ab + \frac{b^2}{3} = 25\to a^2 + ab+\frac{b^2}{3} + 7 = 32\to 2a^2 + ab + ac = 32$$
ren
dude
it's not a uni level question
olympiad?
ok i wont know much and i m studying maths myself so i dont level of this question i just trying to solve
skill any constraints?
mk no problems yet
?
this :p
i still dont know where you get a(a+b)=16 from
i didn't
that was mb
a(2a+b+c) = 32
is what i have on hand
working on it
2c^2 + ac = ab
wut
i don't know where you got those from
wait
but i trust you
nah nvm
ooooooookay
if ur wondering
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
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
ren
what if you square everything
ok this is starting to borderline joke
icl but this form looks really nice
this but replaced the x with b
idk im scared this is like a red herring or smth
really confusing for me

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) ]

hey there
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 $\frac{24}{5}$
sealpup321
which is the answer
but why does that work?
I would get it if you were multiplying by P' but this is just det(P)

find v.a and h.a
you have factored correctly right? one sec ill do it
i found v.a with the help of the discriminant
u can factory it too
but you will get 1 and 5
-1
u have to do the opposite of the factorised
Nevermind u right
so why not 1
at x = 5, there should be a VA
it cancels
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
ohhh but when doing it with discriminant u wont be able to find it
im sorry what?
im not quite sure i understand
you know you could find the v.a with discriminant right?
discriminant? of what
discriminant of denominator
isnt that a matrix thing
well
yeaaa I guess you can
but it can be inaccurate
yeah that is what im saying
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
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?
None
Any you've tried?
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
Yeah, thats what I did
and it wasnt 0
x does not exist
Actually said what I was thinking but it’s not possible as n^0 =1
put -infinity if you’re that pressed for an answer
or DNE
Imma just put no solution
If you want something more rigorous, we can try taking the natural log of both sides
What's that
$ln(36^x) = x, ln(0) = \text{DNE}$
m. frost
It's the opposite of exponents, basically the function that gets the X in 36^x
Well ln(0) is undf btw
Thanks guys
But ln(0) is undefined so a^x = 0 can't exist
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?
it is not asking you to find n, but just saying that the integration constant depends of n
Can you explain that further for me?
I don't get it.
Why is it for 21 and 23 but not 19?
@obtuse willow Has your question been resolved?
@obtuse willow Has your question been resolved?
Hi @obtuse willow
Hello!
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
So whenever I have an anti derivative that includes tan or sec.
I have to take that into account?
Wait the answer to this includes sec.
Why doesn’t it include the pik thing @brazen moth?
Yup
No I mean…
Why doesn’t 19 use this?
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
Okay.
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
?
Yeah sure
Is it possible that cos and sec are “balancing” each other?
Since Sec is 1/Cos?
Oh.
I dunno how to describe it.
But could it be possible that the one Cos lets Sec be defined somehow?
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
Sec covers parts of the graph
That cos can't
And it's true the other way around
I see.
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
Very
Cos x^2 and secx ^2
They fill each other out
To perfection
Covering all of infinity
The reason why i love math

Would this be correct? I don’t know how it will have a sum.
@weary flare Has your question been resolved?
It's not that the terms diverge, it's that they don't converge to 0.
But yes, you're right

Help pleaseee only the first one
function is increasing and decreasing is when theyre talking abt slope no??
i think so
so like you just need to figure out when the slope is negative and when its positive
so were lookign at both axis or...
awm no??
idk wym by axis, u just look at the slope
rise over run
x and y both negative and positive
??
is the first one like...-2.5
u dont have to determine the exact slope, u just have to identify if the slope is negative or positive
oh sorry i meant like this
ermmm
negative..
i think
okay domain wise 😭 😭
the x values, x-axis
is that what u meant earlier
yaaaaa
aurrrr
my eyes arent really all that good but ill tryy
u look at the x-values or x-axis to determine the intervals
its okay, an estimate is an estimate
unless if u estimate like
234892 when the x-value is 4
then ill be like sideeying hardcore
are u looking between -2 and -1 or smth
uh huh
okay let’s
divide this function into different sections
so it’s easier to visualize
oki
ahhh i thought as muchh
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
uh huhhh
A crest?
is it like the minimum and maximum thingy...
sort of
so yk this is negative right
oh is it called that
honestly I blocked that out bc of physics trauma
Yeah the bottom things
Lol it's alright
Ik you thinking about wavelengths
EW WAVELENGTHS
censor it for me 🥰🥰
w*v#l#ngths
anyways @cosmic tiger ^^
yaaaaa
-1.5, 2
waaaaa
this is technically correct but for smth else
that’s the increasing part
omg...
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
oh gurl
u see the arrow at the left end of the function right
isnr both negative...
pos
no neggg
its on the negative sideee
so u found a part of one interval
-infinity
so the function is decreasing from negative infinity to what
o#
you already figured out the function is increasing (-1.5, 2) right
the intervals
so where’s it’s decreasing
-1.5
YASSS
(-infinity, 1.5)
OKAYYYY
THATS ONE OF THE DECREASING INTERVALS
there’s still one more
yas
always union
unless the problem uses the word “or” always use union
(2
okay
neither
YASSSSSSS
🎊 🥳
yaaaaaaaaaaay
me after getting over with my calc quiz tmrw
tell me u now know what to do
Go on.....
(-infinity,1)
Good start
yas
union
uh huh
(4,positive infinity)
It was going so well
this is when the function is what
4 arrows
ye 4
uh,
cant remember
is it like the or thingy
THE FUNCTION??
ian know
ohhh
The function go up then down then up then down
It go up from
(-infinity, 1] U (3,4]
And go down from
(1,3)U(4,infinity
oh
maybe i have eye problem so i can barely see
I think @polar socket has just left
Nah it's alright
You new to this
Jokes aside
It takes everyone time
So nothing to be embarrassed about

,rotate
Couldn't find an attached image in the last 10 messages.
First find y',which gives us the slope of the tangent in terms of x.
what have you done so far
:p
Hmm done got -x/x+1
At first I thought of getting y' and then comparing graident but I have no idea what to do aft y'
Only thing I know is that all the tangents would have the same graident
Hint:y-y1 = y'(x-x1)
Hmm I suppose this is the eqn of the line that the tangents pass through that are also points on the curve ?
You also know that the points that you have to find are supposed to be on the curve y=x/1+x
Hmm I equate the 2 eqns?
❌
Oh
Oh Alright lemme try it
I meant to say substitute but both lead to the same result
Ahh alright
I. Got a quadratic
The solutions for x are long demical places tho
I feel I might have made a mistake somewhere
What the
Ok nvm ans key also have weird demcimal places lemme try
Wait I don't understand smth this gives u the eqn of a line so by using the graident and the coordinate don't u only get one solution for the tangent ?
No
For example

Calculus 2
I dont get how to do this, i was thinking y = t and then parametrize, t € [0,5].
But it would be two equations
