How did we get x = 0 and x - 4 = 0
maybe this will help
Okay, i will try.
divide both sides of** x(x-4)=0** by x
which is x-4=0/x
which is equal to x-4=0
you immediately lose an answer
since you assume $x \neq 0$
Remavas
Bottom line: DON'T divide by x

Could you please tell me why we have taken 1 and 2 here and not any other number?
I mean why we did what we did?
I can't understand this solution
the idea is to get rid of the absolute values in the equation and as |y|=y for y>0 and |y|=-y for y<0, we consider for each |...|, whether the interior is positive or negative to simplify it
How are we getting rid of the absolute values?
if x-1<0, then |x-1|=-(x-1)=1-x so we can replace |x-1| with 1-x and get rid of the first one

Hello,
I recently came across Fibonacci Sequence and found it very interesting. However I am unable to find its applications in real life. I would like to know where it is used.
Thank you!
In music: In a scale dominant note is the 5th note of major scale which is also the 8th note of all 13 notes that comprise octave. This is an instance of fibonacci numbers in key musical relationship
also, the spirals of shells, seeds on a sunflower ,and even the curves of waves

what is the rule for this?
just multiply by sqrt7
x²/x = x
on both sides
factorize 7
oh ok thanks
as a product of sqrt
Or x/x² = 1/x

On the interval -4 to 2
That last one on the very right is confusing me
Do you count that if it’s on the boundary or not?

Not sure how to solve this could I get some help?
Partial fractions, a nice thing.
Do you know where to start with this?
Not to sure to be honest
how would you combine the two fractions?
Don't combine the fractions
First step would be multiply the first fraction by B's denominator and then multiply the second by A's denominator
yes...
Technically I'm getting the fractions ready to be combined but...it's not needed
show us your progress if you can
Even if it's just text
13x + 18/5x + 14 and 13x + 18/x-3
You should still have As and Bs in there
A(x-3) + B(5x+4) = 13x+18
Ignoring the denominator
btw
in this point
you could choose A to be like 1 or 2 or 3... etc
and just try to solve for B
Since you just need to find some value A and B so it fulfills the equation
ok
Whats the next step I take from here?
so
ok
it can be any value?
any.
ok
but youll need to solve for B later.
Thanks
2
so B should be 2?
ok
then how many times does x fit into 3x?
3
so then should i input those numbers to find A?
nvm
you just need to choose a number for A or B
like if i choose A = 3
then 3(x-3) + B(5x+4) = 13 + 18
i would solve for B then.
10x +27/5x + 4
its basically guessing game rn
i have the answer if that would help i just dont understand how my teacher got there
so
B should be 3
so that 3(5x + 4) = 15x + 12
then just
13x + 18 - 15x -12 = A(x-3)
ok but how did you knwo b was 3
i just guessed
😂
cause a equation is solvable only if theres only 1 variable
how
I remember how you're meant to do this
please
For A(x-3) + B(5x+4)
Set one of the x values to make the bracket = 0
So for A(x-3)
x must be 3 for that to become 0
Then you can solve for B
oh damn
And then you can find A after finding B
right...
Sorry for diappearing too
so A(3-3) = A(0)
So then you only have to worry about B(5x+4) = 13x +18
Means you only have 1 unknown
and some number multiplied by 0 is just 0
oh
Better to have 1 unknown than 2
never thought of this 😭
ok thank you
All good now?
😂
Got there in the end!
Yeah about that I just tried this strategy with another question it didn’t work can you help me one last time to figure out where I went wrong
For that type of question I believe you need to set x = 0 as one and then x = say... 1 and then solve it simultaniously
or you could do $6x+7 = A(x+2) + B$ and match the coefficients
elemen
let me try that out one second
Yeah, multiplying by (x+2)^2 makes it a lot easier
another one of these...
If you do it the way that Elemen said. You will get
A(x+2) + B = 6x+7
Set x=-2 to get rid of the A bracket and solve for B
I was thinking for cubic partial fractions
💀
ok thats what i did orignally but why do we forget the (x+2)^2
??
the
orignal b denominator
oh ok
only the numerator stays
am i wrong or would a also equal -5
wait what did you sub in to get a
i thought it was -2
x was originally -2 in order for you to solve for B
ok but how did you know to sub in 0 to find A
It's not really about knowing as such, it's just down to keeping A there. We know B already from subbing x = -2 into the equation
oh i seee
Does that all make sense?
yeah thank you so much
No problem!
i see
thank you, PJ 😄

Shade the region of points that satisfy the inequalities x + y ≤ 7 and
x − y > −3.
I know how to solve for y in these and graph for one of them but I don't really understand the question
<@&286206848099549185>
once you read ^, shade the region separately for each of your inequalities.
further examples if you're still confused
https://www.onlinemathlearning.com/graphing-inequalities.html
boy, draw the those lines on a cartesian plane
none of them go through 0,0
0,0 lies inside the region or outside the region they’re asking for
do that for both and you’ll be able to find which side of the line they’re asking for

how do i convert the general form quadratic equation x^2+4x+3 to standard form? i tried and got (x+2)^2+3 but my math program for homework says thats wrong
You need to complete the square with the 2 term x^2 + 4x
One way to check your answer is to expand your answer and make sure you get the same thing as what you started with
okay! umm, how exactly do i do that?
You can probably look up complete the square, but it involves adding some number (and subtracting the same number to keep the expression unchanged) so you get a perfect square trinomial
i see! i attempted that by doing 4^2 over 2, and got 4 as the result, so i added and subtracted that along with adding the 3
It's (4/2)^2 = 2^2 = 4, but yes
So:
x^2 + 4x + 3 = x^2 + 4x + 4 - 4 + 3
Can you see a perfect square trinomial?
@pale arch
ah sorry! umm, is the perfect square trinomial x^2 + 4x??
that's not a perfect square or a trinomial
possibly google what a perfect square trinomial is
shoot
yeah i should do that LOL
is....4 the perfect square? and is x^2 + 4x + 4 the trinomial?
well 4 is a perfect square and x^2+4x+4 is a trinomial lol
that trinomial is the perfect square trinomial
how can you rewrite it?

George loves his friends but recently his relationship has gotten shaky. In a certain conversation, his interest for his friends decreases at a rate I(t) = 1/x-x^2 measuring in interests per second where t >= 0. If George initially started with 100 interests how many will remain when t = 4 seconds? Will George be able to attend the fair?
did you attempt the prblem
idk how to itnegrate it
"idk how to integrate it" "take the integral"
For more free math help, visit www.TheVirtualMathematician.com
In this video we will learn how to integrate functions raised to some power, such as x^4. The Power Rule for integration is one of the most basic integration techniques that we will learn in calculus, and is likely the first integration technique you will come across in your studies...
"idk how to integrate" isn't a sufficient answer if you're in a calculus class that has already covered differentiation etc
an attempt is always better than saying "idk"
i do not care
because we can see what you don't know
Based
then why'd you respond lol
cause i was giving the person who asked the question a link that will help them
you added nothing besides a helpful video
I'm fine with you providing the video. It doesn't change the fact that saying "idk" doesn't help anyone. Since you don't care, we'll leave it at that
What are they supposed to do? Manifest the knowledge? If they don't know, they don't know my guy. Assuming they actually don't know, of course
i was just saying that you don't get a question like that when you're first introduced to integration though
you normally play around with rules(atleast I assumed )
and basic functions like x^2 etc
There's a lot of integration rules. It's easy to forget, if you're not great at it, like many students are
this isn't a test though
it's like sending an email or whatever with the "No hello" thing
Still, we should give the benefit of the doubt. If the other person says they don't know how to integrate the function, we should take their word for it. We could then either help them remember, or send them a video, or something.

@subtle mantle @fringe yoke thanks mods for helping me
what is the defn of a coordinate chart
im not really a helper but i can try lol
Each point of the surface S has to be 'covered' by a point in Phi, the coordinate chart
dont spam
map it to an altas 
Ain't this differential geometry?
I have not had it formally defined. I just need to show that all points of a surface S has a corresponding point in the coordinate chart Phi
And what is surface S?
Well I think that's the problem
finding a surface S that has Phi as its coordinate chart
I will do it as soon as I know what an atlas is 🗺️

how would I approach a taylor series like this
thus far I have written out all the derivatives for the function
but I'm not sure how I would proceed because cos(pi/4) is like rougly 0.70
so it alternates every 2 signs
so how would I represent that in series form
You don't want to put 0.707, you'll want to put √2 / 2
ooh i see
let me try to represent it but im not too sure about how to make it alternate signs every 2 terms
instead of one
Actually it looks like you've got it
You just want the sign to alternate after every two, huh?
yeah

Hey guys I need help with questions 4 a)
Closed due to the original message being deleted
This is tutor homework. No exams or assignment for me to cheat on haha. My tutor has provided his answers but I still don’t get the question. I tried to use the general form ( I think that is incorrect) and tried to understand binomial expansions (I still don’t understand). I don’t really get the whole concept.
I assume you know how to expand (a+b)^9 which will have the general form (9C0)a^9 +(9C1)a^8(b)…
Sorry could you write that down on paper so I cna see the formatting?
Thank you though

can someone explain to me how to solve it <@&286206848099549185>
please wait 15 min after posting question before pinging helpers
but i can help @tardy spire
Oh sorry
i gott x=60 , y idont know
Which circle theorems do you think would be useful to use
hmm
how are you getting 60 for x
is that a guess?
I mean x does equal 60 but if you already worked that out then the rest shouldn’t be too hard
I mean it is,but it depends if you're able to justify that properly
wait really
and technically you don't need to find x or y to determine x+y
Yes
you get a lot more info than that
hmm
🥲 i dont see it omg im too bad
do you know what an equilateral triangle is?
it takes me so long to find the answer
<@&286206848099549185>
what have you tried
in a 40 liters there are 8 L of bleach and 32 L of water
30% more?
nah. doesn't work like that
you know, if the solution is 50%, there's equal parts of water and bleach right?
wait wait. we are at the step where we add bleach to make the solution from 20%-80% to 50%-50%
and you said that the 20/80 solution has 8 Ls of bleach, and 32 Ls of water
so, how much bleach do we have to add to make the quantity equal to the 32Ls of water already present in the solution?
24Ls?
correct
so you add all that bleach. and now you have a mix of 32 L bleach and 32 L water
okay...
now you have to add more water. let's call the quantity you have to add X
so, in the end. the mixture will have 32 Ls of bleach. and 32 + X L's of water
and the ratio of bleach to the total quantity will be 20%, or 0.2
try to turn that into an equation
hm no that's not correct
ehhh
o no wait
you're right
i didn't understand the equation you wrote. but the answer is correct.
ahaha mb
thank you so muchh
u r totally a genius
😉 .
the simplest way to write the equation is 32/(32+32+x) = 0.2
wait how u do that equation
total quantity of both bleach and water?
yes. this is what is meant when it says "20% bleach solution"
np 👍

Can anyone please tell me how I would rewrite the first one
I just need to know what exactly they’re asking for.
Probably asking you to convert to index form
Rewrite into something easy to differentiate
Differentiate that
Simplify the result
e.g 25. can be rewritten as $\frac{5}{2}x^{-2}$

Does anyone know about the Perrin numbers
P(n)=p(n-2)+p(n-3)
I don’t know it but I can only know that to calculate it’s expression. we need to consider the polynomial x^3-x-1=0, if it has three distinct roots r_1, r_2 and r_3, then p(n)=Σc_k(r_k)^n. Then we need to know three terms of P(n) to obtain a system of linear equations of c_1,c_2,c_3 to solve them
If it has a three-multiple root r, then p(n)=(c_0+c_1(n)+c_2(n^2))(r^n)
If it has a two-multiple root r and a single root s then it equals (c_0+c_1(n)(r^n)+c_2(s^n)
(The characteristics polynomial has a single root r,then r^n is an element of the basis. If it has a k-multiple root r, then r^n, nr^n, n^2r^n,…,n^(k-1)r^n is part of the basis)
I think they're talking about the relation of Perrin numbers and prime numbers
( I assume he knows that all sequences P(n) such that p(n)=p(n-2)+p(n-3) forms a linear space, and Jordan form or matrix those kind of things)
?
I thought he wanted to calculate the expression of p(n), he didn’t say anything about prime number

1ii)
Can i use simultaneous for this
since C E B points are collinear
so im thinking to use gradient to find the first equation for x and y
and then i use the shoelace method to find the area
then sub in the first equation then do the factorisation
overall the step is overwhelmingly long
stilll i couldn't get the ans
i wonder if my method is correct
or could there be any careless mistake i checked it thrice but still i couldn't get the ans
the ans sheet shows another method (ratio method) which I haven't learnt b4
so this question really got me,,,
Heres my working btw
here's the ans sheet :sigh:

Hi I've done the first part of the question. I'm wondering what's the method for going about doing the second part
Lookz like a magnifier
Right comes against left, then redirect it
Let and right creates opposition
Redirect the outcome to make use of it
Write the general equation of C_2
I would just make function of distance from origin by t, and find its max
yeah so I started with x^2 + y^2 = r^2
Mhm
I'm confused as to what you are saying
which 2
O and C1
return 1 from what exactly?
you got x all around, you have to makr it pick one side instead 1
From the combination you got of 4 sides
I have the cartesian equation for c1
What is it?
This
Write it down
top part
)(
Hmmm
You're still left with 2, although it's really 1, need to make it return something elsr
x, that's what you got right now
Which is 5
Hmmm
sorry, but I'm really confused at to where this 2 is coming from
@alpine sable don't troll.
Sorry
I'm trying to explain using my method, i usually talk like that
You're speaking nonsense tbh
Sorry @alpine sable, are you actually going to help? otherwise I'll wait for someone else
@alpine sable shut up
🙊
It's pretty confusing
@balmy warren have you tried solving for the points of intersection?
Elaborate?
@alpine sable shut it
I think so. I subbed in my workings into the circle formula
so I got r^2 in terms of x
but not sure what to do from there
yeah, you get $r^2-x^2=\frac{9}{4}x^2(4-x^2)$
Mosh
which is $\frac{9}{4}x^4-10x^2+r^2=0$
Mosh
yes!
Mosh
oh wait
I know where I've gone wrong
mixed up my addition
ended up with $100+9r^2$
IntelligentCake
Mosh
is it because how functions work.
no
oh
if $\Delta <0$, then you wont have any intersections
Mosh
oh wait, because it touches the circle right
and if $\Delta >0$, you get 8 solutions
Mosh

Uh what?
Mind explaining in simpler manner?
∆ is 8?
So ∆ = 1
∆ also equals = 2
How can I say find the opposite of it? What's the opposite of ∆?
or that
Hm
Erm
So 3 oposites
I guess
+-∆ 8
-∆8
+∆8
Does this work?
+-∆ 8 neutrial
-∆8 minus
+∆8 plus
idk this is too advanced for me. also how u wite delta like that
Where's delat in between these?
Well
You combine and boom you got neutrial force
+- is collecting + and -
Like 1+1 Is collection of 2
1-1 is also collection of 2 really yet it's opposite of the first one
So
+-
Alpha delta omega
What ya think
I think i got it right
So say i want to appose all
Alpha omega and delta, the opposite would be a replica of it, that is alpha since it would be 2 collections apposing each other
Essentially how magnets work
Both magnets are alpha
∆ vs ∆ push each other away
That's why you can throw a magnet on top of another if you got the right side and they wil push each other for ever
Interesting
To pull, as in make the magnets work you use + and -
Because + pushes
And - pulls
In reality they really both pull each other, they work together if you we're not to use both against another double of it self
2 forces
)( = ∆ + ∆ (push)
| = ∆ (pull)
Essential you could also say there is a third one that does "nothing" even though it's technically doing something, it's when the magnet it self is not really facing another
∆ + ∆ + ∆ = π
3 neutrials equal pie because it's not complete
You can also do π + π = )(
(oppositional again)
Because both uncompleted, they try to complete but both uncompleted
Not hard, interesting
Just needed some thinking really
Thanks for the assistance

i collect apples, i eat 1/3, i give my friend 3/5 and nowi have 4 left, how many did i collect att the start
Please don't occupy multiple help channels.
Write an equation
3/5 of what you have after eating 1/3 or 3/5 of collected apples
15
yes
,w x-1/3-3/5=4
no.?
why
thats what the answer says in the answer check
no
the x is 15
it should be like
it says
no
basicly
no
6
i swear want a screenshot
k
ye
=4
yes
He got 15 Because “I gave my friend 3/5” means I gave my friend 3/5 of apples remaining (apples I ate aren’t counted)
huh?
5+3+4?
u told u s the problem wrong
lol
sorry
np
so how do i do iẗ
can u help me in #help-4
i need help w this

nothing
Don’t understand the meaning of English word directrices there
do u mind helping me

Why suppose n>=2 and n-1 ? Why was not n=k then n=k+1 ? Can someone explain this please ?
So you need to understand what you're proving
K is your iteration variable
you dont really want to increase that
you're proving n for any number

What numeric values for B would make it equal -> -5^b and (-5)^b
would it be 1?
$(ab)^n = a^nb^n$
KurtDee
-5 = -1*5
so how do I do it
where are you stuck
what do I do with the exponent rule
I mean like what are you really trying to do here
solve for b
so how do you want to do that
-5^b and (-5)^b
what would b be to make them equal is the question
what would I do first
?
I mean ideally you should equate the exponent base
you're dealing with two different bases, 5 and -5
Well what is (-5)^b? Using that exponent rule above
(-1^b 5^b)
Right, and what is (-1)^b
(-1^b 1^b)
Well yeah, but that doesn't help us any more
(-1)^b depends on what b is. If b is even, it'll equal 1, and if it's odd it equals -1. Do you see?
Anyway we might be getting off track
So your equation now looks like $$-5^b = (-1)^b \cdot 5^b.$$
abs_0
You can see there's a 5^b term on both sides, and if you divide both sides by 5^b you get...
so yeah b needs to be odd numbers I'm guessing
Don't make that decision prematurely, I was just pointing it out. We don't know yet
oh ok
So what happens when you do this
-1^b
It should be an equation
Take this and divide both sides by 5^b. What equation do you get?
-1^b = (-1)^b
You should get -1 = (-1)^b
And from our discussion before, this is true whenever b is odd. Therefore the possible solutions for b are all odd numbers

I know that for n -> infinite the series converges to -1
for n = 1 it's -2
so are the infimum -2 and the supremum -1 ?
