broken bough
#

How do i do this i have this as an example but i dont understand

wary kite
#

what is the goal?

#

the instructions are cut off from the picture

marsh citrusBOT
#

@broken bough Has your question been resolved?

broken bough
#

Youd have to tap on it

wary kite
#

x = 4 is given so all you need is to solve for y

#

just substitute x = 4 into the top equation

broken bough
#

Okay

#

Like this?

wary kite
#

exactly

#

now what does that come out to

broken bough
#

5

wary kite
#

mhm

#

so y = 5

#

x = 4

#

(4, 5)

broken bough
#

Ohh okay thank you so much i have one last help with this one hold on

#

I dont understand how to put the word equations into an equation

rotund pike
#

What do you mean by putting a word into an equation?

#

Oh, I get it.

#

The word problem.

wary kite
#

you don’t have any idea of how to translate it into math?

broken bough
#

Like i just need help in putting it into the equation correctly

wary kite
#

how about this, can you tell me how much it would cost to get two photos from lightning fast foto

tired monolith
broken bough
tired monolith

try solving it first.

tired monolith
broken bough
#

Yes please

tired monolith
#

man I'm explaining bullsht

#

let me redo that sorry

tired monolith
broken bough
#

Which place is cheaper?

tired monolith
#

not quite

tired monolith
#

let me make an equation and I want you to dissect it

#

5 + 0.2p = 7 + 0.1p
fee fee

#

both sides are the fee don't pay attention to the variables

#

well actually the variables do matter

broken bough
#

Okay

#

Is x 20?

broken bough
#

What about 2 on this one

Was looking to see how you guys would interact w the canceling of these units along with an explination. I know the first two interactions end in multiplication but apperently the last one ends in division which I dont completely understand.

\textbf{Theorem 6.42 (One-sided derivatives of a convex function)}
Let the function ( f ) be convex on an open interval ( I \subseteq \mathbb{R} ). Then ( f ) has finite one-sided derivatives from the left and from the right at every point ( a \in \mathbb{R} ).

digital chasm
#

Can someone help me understand sine and cosine law

potent reef
#

What do you need help with?

digital chasm
#

Trig

#

It’s like finding the angle without it being a 90 degree

#

Angle

potent reef
#

What angle?

#

Please show the original problem, exactly as it was stated to you, with the entire original context. A picture or screenshot is best. If the original problem is not in English, then post it anyway! The additional context might still be helpful. Do your best to provide a translation.

#

these ones?

digital chasm
#

I think so

potent reef
#

What was the original question?

#

You either need to show the original question or articulate more clearly what problem you're facing with something.

digital chasm
#

The original question was I need help with understanding sine and cosine

#

Law

summer grove
#

like, understanding hwo to use them?

digital chasm
#

Yes

#

Because I was trying watch YouTube videos and I was still confused

summer grove
#

this is what it means

#

A, B and C are angles

#

and the ratio of the sine of the angle to the opposite sidelength is equal for all angles and sidelengths

#

to put it awkwardly into words

digital chasm
#

I get that part

summer grove
#

so what more is there to understand?

#

here, try solving this one

#

A is 40, a is 6, b is 8

#

what is B?

digital chasm
#

Ight I might not get it

#

So is it 40sine 6 for A right

summer grove
#

no

#

A is 40 degrees

elfin berryBOT
#

Result:

0.64278760968654
digital chasm
#

So do the side of a go to the bottom

summer grove
#

look at this equation

#

you have A, a and b

#

you should be able to get B

digital chasm
#

B 8 right

summer grove
#

no

#

b is 8

digital chasm
#

What the difference from what I said

summer grove
#

B is the angle

#

b is the sidelength

#

big difference

digital chasm
#

Oh

#

Is the angle A

summer grove
#

yes

#

A=40 degrees

digital chasm
summer grove
#

then solve for B

digital chasm
#

Did I set that right to find b

summer grove
#

yes

#

well, close enough

digital chasm
#

30.9

summer grove
#

thats not quite right

potent reef
digital chasm
#

Wouldn’t you cross multiple

glossy flint
#

You just need to multiply everything by 8...

#

You don't always need to cross-multiply

digital chasm
#

Is it 48

glossy flint
#

Nooo.

digital chasm
#

Yeah am cooked

tu comprends pas quoi

dark oxide

serene briar
#

tu connais le théorème de continue des intégrales à paramètres ?

dark oxide
#

non

#

si qui

#

where are u

serene briar
#

bah si tu le connais pas pk tu veux essayer de faire des exercices dessus

floral prairie
#

grosso modo une intégrale à paramètre c'est quand tu intègres une fonction (intégrable) F(x,t) à deux variables sur une des deux variables, par exemple tu intègres F(x,t) sur t, et tu voudrais voir comment varie l'intégrale en fonction de l'autre variable, ici x

#

Tu as des théorèmes de dominations etc. qui te permettent de déduire rapidement qu'une telle intégrale varie continuement en fonction de x

#

Mais si tu es pas à l'aise avec les intégrales, c'est peut-être pas à ton niveau, parce que tu as de nombreux théorèmes que tu dois savoir utiliser etc. Genre c'est quoi ton objectif @dark oxide ?

serene briar

le vent qu’il te met 😭😭

en vrai après avoir bouffé ça en agreg, crois moi je le recite en dormant ce truc XDDD

serene briar
#

carrément t’as l’agreg toi

floral prairie
#

oue

#

scuse nous

floral prairie
#

en vrai c'est pas un concours dur genre ca montre juste si tu connais bien ton cours

serene briar
#

MDR mais pardon terence tao

floral prairie
serene briar
#

c’est pas chill les développements

floral prairie
#

blague à part je comptais aider énorméemnt de gens en maths ou autre cette année parce que j'aurais bcp de temps donc hésite pas aussi eh

#

même pour des trucs que je sais pas on peut y reflechir ensemble etc

serene briar
#

ayi j’suis pas encore chercheur chef 😭

#

qu’en L2 pr l’instant

floral prairie
# serene briar c’est pas chill les développements

ça dépend, genre y a des dév qui sont vraiment très durs, genre c'est pas "difficile" c'est surtout qu'il faut vraiment le présenter en speed parce que t'es chronométré, puis t'as des dév qui sont vraiment plus simples typiquement tu pourrais les faire en L2

floral prairie
#

et genre si tu presentes un truc trop dur, les questions que le jury va te poser bah ca va etre hardcore

#

donc t niké

floral prairie
#

par contre

serene briar
#

si jcrois

floral prairie
#

tu peux avoir que le groupe multiplicatif de Fp est cyclique

#

ça ça tombe

floral prairie
serene briar
#

bah faut le montrer mdr

floral prairie
#

tous les elements sauf 0 sont générateurs

serene briar

I found the diagonalizing matrix P but I don't know if I did it right

#

I found the eigenvalues ​​$\lambda_{1}=1,\lambda_{2,3}=2$

elfin berryBOT
#

Task Bot
Compile Error! Click the errors reaction for more information.
(You may edit your message to recompile.)

rocky lark
#

So $\lambda_1$ has arithmetic multiplicity 1 while $\lambda_{2,3}$ has algebraic multiplicity 2

elfin berryBOT
#

Task Bot

rocky lark
#

So since I got 3 distinct eigenvalues ​​I can't say that it is diagonalizable for now

#

So I went to calculate the geometric multiplicities

#

And I found that $m_{g}(1)=1$ , so it coincides with the arithmetic one , and also $m_{g}(2)=2$ which corresponds to the arithmetic one

elfin berryBOT
#

Task Bot

serene briar
#

Did you find the 2 eigen space?

rocky lark
#

Yes

rocky lark
#

Yes

#

The dimension would be their geometric multiplicities

#

In more detail I found that $\vect{V_1={(t,-5t,t)}}$, \vect{V_2={(0,t,s)}}$

#

Where t and s are parameters

serene briar
#

Write it with « vect » I think it would be better to show the bases

jandro0103

yes

rocky lark

where even is the question

rocky lark
#

I need to find the diagonalizing matrix P

main idol
#

and where's your work

rocky lark
#

Above

wide citrus
#

we are working together btw

rocky lark
#

I can also take a photo but I don't know when it is clear

main idol
#

how'd you get those eigenvalues

rocky lark
#

$det(A-\lambda I)$

elfin berryBOT
#

Task Bot

wide citrus
#

take a photo

rocky lark
main idol
#

and where are your eigenvectors

serene briar
#

it’s not diagonalizable

wide citrus
#

(sending ...)

main idol
#

are the algebraic multiplicties equal to the geometric multiplicities?

rocky lark
wide citrus
serene briar
#

V2=vect(0,0,0)

main idol
serene briar
#

no..

wide citrus
#

it is

#

explain why

main idol
#

what it is "it" in your sentence

serene briar
#

V2=vect(0,1,0) mb

#

But it’s still not diagonalizable

rocky lark
#

What did I do wrong pls

serene briar
#

the eigenspace dimension associated with 2 is 1

#

and his multiplicity is 2

wide citrus
rocky lark
#

So

#

I did

#

dimV_2=3-1=2

wide citrus
#

Since the rank is 1 I have two free variables which are those not present in the chosen minor, in this case I took the minor -1 at the top left

So I have the system x=0, y=t, z=s

rocky lark
#

And therefore they are the same

wide citrus
#

yes

#

m_a = m_g

#

we got 2 = 2

#

so it is diagonalizable

serene briar
#

no we have 1 bro

wide citrus
#

Since the rank is 1 I have two free variables which are those not present in the chosen minor, in this case I took the minor -1 at the top left

So I have the system x=0, y=t, z=s

rocky lark
#

But the rank is not 2

wide citrus
#

^

#

indeed

serene briar
#

V2=vect(0,1,0)

#

x=z=0

wide citrus
#

yes

elfin berryBOT
#

jandro0103

serene briar
#

so dim=1…

rocky lark
#

No

wide citrus
#

x = 0 , 2x + 3z = 0

serene briar
#

yessssss

rocky lark
#

But

serene briar
#

3z=-2x=0 omg

wide citrus
#

the rank is 1 yes ?

serene briar
#

we only have y

#

yesssss

wide citrus
#

3 - 1 = 2

serene briar
#

with multiplicity of 2

wide citrus
#

so 2 = 2

#

ma = mg

serene briar
#

that’s crazy bro

#

i know how to calculate

serene briar
#

but they aren’t

#

we calculated it and it is vect(0,1,0)

serene briar
#

it would be 2 if A was diagonalizable

rocky lark
#

Why was I wrong?

serene briar
#

i don’t know but it’s not diagonalizable

serene briar
#

It is a characterization of diagonalization

rocky lark
#

I wrote that the rank was 1, however, perhaps isn't and I don't know why

serene briar
elfin berryBOT
rocky lark
#

Wait

#

But

#

[
\begin{bmatrix}
-1 & 0 & 0 \
2 & 0 & 3 \
-1 & 0 & 0
\end{bmatrix}
]

elfin berryBOT
#

Task Bot

serene briar
#

yeah it’s that, now multiply by the matrix X

rocky lark
#

[
\begin{bmatrix}
-1 & 0 \
2 & 3
\end{bmatrix}
]

elfin berryBOT
#

Task Bot

rocky lark
#

Can I consider this minor?

#

Here the rank is 2

serene briar
#

No, you would lose the y

serene briar
rocky lark
#

The first two rows are clearly linearly independent; in terms of minors you can look at the minor formed by rows 1,2 and columns 1,3. In the solution it is written because the rank of this matrix is ​​2

serene briar
#

you’ll lose the 2nd variable

#

the 3rd *

#

you solved it ?

rocky lark
#

No

serene briar
#

okay

rocky lark
#

But I'm trying to find the rank

#

[
\begin{bmatrix}
-1 & 0 & 0 \
2 & 0 & 3 \
-1 & 0 & 0
\end{bmatrix}
]

elfin berryBOT
#

Task Bot

rocky lark
#

Of this

serene briar
# elfin berry **ss**

just solve this and you’ll have the dimension of the eigenspace associated with 2

#

and if it’s not 2, it is not diagonalizable

rocky lark
#

But the thing I don't understand is why the rank is 2

serene briar
#

even chatgpt says it’s not diagonalizable 😭

rocky lark
#

Indeed

serene briar
rocky lark
#

Mmm

serene briar
#

oh

#

i’m dumb

#

rg(A-2I_3)+Ker(A-2I_3)=3

#

so such that rg is 2, the eigenspace dimension associated with 2 is 1

#

which is Ker(A-2I_3)

serene briar
#

it’s good for you?

Guys I want to be good at typing math symbols in Discord or Stackoverflow. what's the most popular and common thing called? Is it Latex?

wheat rover
#

you can use alt codes for some small symbols, but most of the times latex gonna help

#

so yeah if you know some basic latex commands that's gonna help ya

I have some sequence derived from test these are pretty hard and i wonder how i can tackle them:

These are the sequences in question missing is "?",

16 ,8 ,? ,110 ,-935
6 ,33 ,? ,45 ,46
1 ,40 ,? ,1000 , 625
4 , 2, ? ,-2 , 14

These sequences dont make much sense any way to tackle them?

late geode
#

values seem to random

vivid parrot
#

Right, yet there should be a answer according to this test..

#

I have broken my head over them, cant figure it out for my life

late geode
#

what class is this from

vivid parrot
#

No class, its an online assessment for a job position, its category is sequence solutions.

#

I thought I am just stupid, but if math genius levels dont see the answer then atleast i know i am not that stupid i guess

late geode
#

we can't assist with those

Difference between bar chart and histograph?
can anyone show in image the example?

the only difference is the SPACE?

#

just like both your thumbs are fingers, but not all your fingers are thumbs

#

make sense?

summer grove
#

bar charts are a whole range of graphs

#

a histogram is just a specific type of bar chart

ancient copper
#

you could interpret a histogram as a more “continuous” representation

woven condor
#

This is my data for histograph

but yeah, a histogram, as said before, is a type of bar chart

is THIS histograph? @summer grove

It seems the x labels are placed between the bars

theyre divided into bins

Seems right

#

I think the first bin goes all the way up to 4.99

ancient copper
#

methinks

#

the intervals are different?

ancient copper
regal coral
#

Oh I see, the graph was made from the table

ancient copper
#

your graph implies that the end interval is closer than it actually is

regal coral
#

Huh?

woven condor
#

@regal coral @ancient copper @summer grove would this be histograph Y/N

#

???

#

if i mark X axis like this.

do you want help or not?

what the fuck

seems right

actually the first one was fine

but these dont have RANGES.

that's how they look on wikipedia

it does

so like the first bin would be 0.5 to 1

then 1 to 1.5

because in between 1 and 2 must be 1.5

they all have width 0.5

@still temple Has your question been resolved?

rotund pike
#

They wanted to see if their answers were correct.

still temple
#

I chose b, is it correct?

rotund pike
# still temple I chose b, is it correct?

You have to close one of the channels you have, because you can't have the same question on two open channels, because that can lead to people not seeing whether you're being helped in the other channel and a duplication of effort.

rotund pike
#

Why do you think that's the case?

still temple
rotund pike
#

Maybe.

#

I'm asking questions to see why you chose B.

still temple
rotund pike
#

OK, but look at the description they gave. Can you find where they said that 2 is a prerequisite of 11?

rotund pike
#

OK, so B can't be the answer.

#

That's one way to work through the problem.

#

The other way is to draw the graph yourself and see which answer matches yours.

I chose C

rotund pike
#

OK, what is a bridge?

still temple
#

I forgot

#

it connects two vertices

#

i think

rotund pike
#

That's an edge.

#

A bridge is a special kind of edge.

#

A bridge is an edge where, if you delete it, the number of graph components increases.

#

Does that make sense?

still temple
#

yes

rotund pike
#

OK, let's look at C.

#

How many components do we start with?

still temple
#

not sure

rotund pike
#

OK. What's a component?

still temple
#

?

#

not sure

rotund pike
#

Well, think of a map with roads on it.

#

You have cities and roads that connect them.

#

A component of that would be a bunch of cities where you can use the roads to get from one of the cities in that component to any other city in that component.

#

If you have two cities and there's no way to take some roads from one to another, they're not in the same component.

#

Does that make sense?

#

Like the cities in Hawaii wouldn't be in the same component as the continental United States.

still temple
#

ok

rotund pike
#

Not only that, but the cities on different islands of Hawaii wouldn't be in the same component as each other.

still temple
#

Hey man I will stop asking questions, just tell me if my answer is correct

rotund pike

Sorry, it's not.

Currently learning about logs and its rules/laws. I'm curious if there was anything special about multiplying 2 logs, like the same way you can simplify 2 logs being added together/subtracted.

I concluded there wasn't much to take away from it

proud basin
#

dont think so

blazing pulsar
#

You have that alog(b) = log(b^a), so if a is a log and b is the appropriate base, there is some cancellation.

but how

@merry hinge Has your question been resolved?

severe owl
#

2012 = 2¹⁰+2⁹+2⁸+2⁷+2⁶+2⁴+2³+2²

merry hinge
#

but

#

thats just one solution

severe owl
#

This gives you the starting point to find other solutions

merry hinge
#

i did sum of 1+1+2+4+...1024=2048

#

for 2012 i need to remove 36 from this

merry hinge
severe owl
#

2¹⁰ = 2⁹+2⁹

#

2⁸ = 2⁷+2⁷

#

Like that

merry hinge
#

i understand this but... do you not think thats a lot of manual work?

exactly!

#

i did sum of 1+1+2+4+...1024=2048

To get AB we need to use 100 x tan41

86.9 cm

pliant coral

I got 35.6

#

nevernevermind my answers wrong

o

#

DC is 100 x sin32.4

#

53.6

#

And BD is just Pythagoras so it’s 100 squares + 86.9 squared

pliant coral
#

yes

dreamy harness
#

Which is square root of 17,551.61

#

132.5 cm

#

Is that right?

#

i have no understanding of how to solve this except ik the equations for the area of a sector, the length of an arc, and the cosine and sine rules

#

otherwise i have absolutely no clue what to do here

#

the only idea i MIGHT have is to make lines from the left point up and make them touch the places where the two circles meet to find THAT sector area

#

but otherwise im at a loss

onyx venture
#

i dont have the angle in between the two radii (which are going in almost opposite directions)

#

i assume i can use the cosine rule to find it but even then, how?

#

oh wait

#

i understand it now, i need to use the diameter

#

to make it like a triangle first and then use the angle to find the sector area

#

oh wait, that doesn't work though

#

because the two intersections are not completely opposite of each other

#

can someone help i have no idea what Im doing

\textbf{P3.} The carts A and B in the figure are connected by an ideal rope, which passes over a fixed (also ideal) pulley. A force $F = 25$ N pulls cart B parallel to the inclined plane downward. Cart A has a mass of $2$ kg, cart B has a mass of $3$ kg, and all frictional forces are neglected.

\textbf{P3.a.} Calculate the acceleration of the system.

@buoyant jetty Has your question been resolved?

sacred idol
#

and where are you stuck?

#

you almost finished the problem

#

only step left is to write the force equations for both blocks

buoyant jetty
sacred idol
#

say it moves with acceleration a in the horizontal direction

#

now the only horizontal force is tension

#

use Newton's second law to write the relation

#

F = ma

#

what would you get then?

buoyant jetty
#

F = 2a

sacred idol
#

here F is T

#

T = 2a

#

can you say what acceleration of B is then?

buoyant jetty
buoyant jetty
sacred idol
#

wouldn't matter

#

B moves along with A

#

both are connected by a taut rope

buoyant jetty
#

wdym Moves along?

sacred idol
#

if I move B by some distance d

#

A should also move by d

#

if B has velocity v

#

A should also have velocity v

#

same goes for acceleration

#

this is true for movement of any two particles connected by a tight rope

buoyant jetty
#

hmmkay

#

seems like hard to understand

#

what about sum of Forces of B

#

how do I figure out the tension

sacred idol
#

tension is same everywhere along an ideal rope

#

so tension force on B is also T

buoyant jetty
#

?

#

what about the sum of forces in B

#

in B is tricky because normal is not the same as the weight

sacred idol
#

do you know how to resolve vectors into two?

buoyant jetty
#

into x and y components?

sacred idol
#

somewhat like that

buoyant jetty
buoyant jetty
sacred idol
#

a vector can be resolved into one along x axis and other along y axis

#

say the vector makes angle $\theta$ with the x axis

elfin berryBOT
sacred idol
#

then the component along the x axis is $F\cos \theta$ and the component perpendicular to the x axis is $F \sin \theta$

elfin berryBOT
buoyant jetty
#

which vector are we talking about doe

buoyant jetty
sacred idol
#

every force in the diagram you showed is a vector

#

forces are vectors

buoyant jetty
#

for Wb

#

how do I find the weight

#

mass of B is 3

#

but idk

#

how do I find the normal of B

#

F = 25 sin(37)

#

what about normal weight and tension

still temple
#

So W_B = M_B * g

still temple
#

Here we are hence only bothered about the component of W_B along F (or inclined plane)

buoyant jetty
#

how do I find Wb

#

should I watch a video or no

still temple
#

You should

buoyant jetty
#

Wb = 3a

#

problem is at an angle

#

a = g

sum of masses = (3+2) = 5kg

#

3a = Wbx + 25

#

3a = 18N + 25N

#

,calc (18+25)/5

#

,, a = \frac{18N + 25N}{3kg + 2kg}

Result:

8.6
buoyant jetty
#

because they are connected by a rope

#

they have same acceleration

#

in this case sum of forces in x

#

in this case the free body diagram of B

#

indicates that the force F = 25N pulling the body B downhill is in the x axis

#

we are given Wb = 3 x g = 30 N

#

but we need to find Wb x axis component

#

Wbx = 30 sin (37°)

#

,w 30 sin(37°)

Wbx ≈ 18 N

buoyant jetty
#

like T ≈ a . 2 ≈ (8.6).2

#

,w (8.6)*2

elfin berryBOT
buoyant jetty
#

T ≈ 17.2 N

#

a ≈ 8.6 m/s^2

#

fnet in x

#

Wbx + 25N - T = Mb . a

#

T = M_A . a

#

Wbx + 25N -(M_A . a) = M_B . a

#

Wbx + 25N = (M_B . a) + (M_A . a)
Wbx + 25N = a(M_B + M_A)

#

(Wbx + 25N)/(M_B + M_A) = a

#

I think I got it broo

#

I like physics I like it

#

I am liking it bro

ripe sun
#

Bro what

#

Holy shit im failing

main idol
#

x^2 -4x - 10 = x^2 + bx + c

This is a short, animated visual proof showing what is meant when we "complete" the square algebraically and justifying why the formula holds for positive real numbers. #mathshorts​ #mathvideo​ #math​ #completingthesquare #mtbos​ #manim​ #animation​ #theorem​ #pww​ #proofwithoutwords​ #visualproof​ #proof​ #iteachmath #algebra

When are you allowed to switch integral and sums?

dawn grotto
#

as in their places?

#

As in something like this

summer grove
#

im pretty sure the conditions are quite complex, but most of the time (esp when working in some type of real world applications) you can swap them

spark otter
#

If all f_n are non-negative no problem

dawn grotto
#

Yeah but why?

static quarry
#

there are several sufficient conditions depending on whether this is riemann or lebesgue integration

spark otter
summer grove
#

ah wait, this is real analysis right?

dawn grotto
#

How do I prove that?

spark otter
#

this is lebesgue integration i think

static quarry
spark otter
#

yeah it's monotone convergence theorem

static quarry
#

for functions that are not necessarily positive, the dominated convergence theorem is the usual tool

spark otter
#

otherwise you would require $\sum_n \int_\Omega |f_n|d\mu < \infty$ or $\int_\Omega \sum_n |f_n|d\mu < \infty$
