#

Doing this is probablyy not the way to go since too verbose

#

But I’m running out of ideas

#

Our number is a multiple of a perfect square

#

But that doesn’t help us that much

#

Would anyone have ideas?

Maybe a step that narrows everything down a bit is to notice that your product on the left is bigger than the sum of the digits to the 5th power. Therefore, the digits have to be less than or equal to 6

fickle laurel
#

That's a good point (because 7^5 > 10000)

#

Although I'm not sure how I could use that information other than accelerating my python script to find everything

dreamy yacht
#

We can go further to less than or equal to 5

odd edgeBOT
#

@fickle laurel Has your question been resolved?

fickle laurel
#

5000 would be greater than 5^5=3125

#

So left hand side bigger than right hand side

#

So I don’t think we can bound similarly to what we previously did?

dreamy yacht
#

6^5 = 7776

#

So if we had a 6 our first digit needed to be at least a 7

fickle laurel
#

Ah

#

Fair enough

#

Good point

#

Does make the search easier but still ain’t convinced that’s what my teacher suggested with analytical solution

That is because you don’t do that

Every time you see a + or a -, what’s behind is a whole thing

Everything behind it is only one thing

What do you mean? You've computed both factors of the chain rule.

It’s finished

latent scaffold

So it should be elementary for such an astute student as yourself to compute the derivative by applying the chain rule you started yourself!

Hi community, I'm trying to use the finite element method to get laplacing for my 2d image, could you help me please?

next parcel
#

I see on wikipedia there are two methods:

#

the 5 point of
0 1 0
1 -4 0
0 1 0

#

Then the 9 point
0.25 0.5 0.25
0.5 -3 0.5
0.25 0.5 0.25

#

Which one should I use? I saw on wikipeadia that the 9 point is better for accuracy, but what's the difference between the two 9 point filters here?

#

Thanks very much🙏

In mathematics, the discrete Laplace operator is an analog of the continuous Laplace operator, defined so that it has meaning on a graph or a discrete grid. For the case of a finite-dimensional graph (having a finite number of edges and vertices), the discrete Laplace operator is more commonly called the Laplacian matrix.

The area of a small rectangular window is 306 cm2

. If the length exceeds the width by

1 cm, what are the dimensions of the window?

I have tried substituting and I ended up getting stuck at w^2 + w = 306

#

What am I missing in my understanding of substitution problems like these?

hang on, is it 306 cm or 308 cm?

I watched the video but it doesn’t correlate. I’m not sure

#

<@&286206848099549185>

wise jasper
#

When doing a question like this, it is important to identify three big things.

#

Speed, distance, and time.

#

Which of the three do you know?

#

@cinder basalt

cinder basalt
#

I know the speed equations

#

And how to apply it

wise jasper
#

In this question

cinder basalt
#

However the part I’m struggling with is the bearing

#

I’m not sure how to draw it

wise jasper
#

I think that is unimportant

#

not very sure though

cinder basalt
#

And you have to use trigonometry

cinder basalt
wise jasper
#

Ok, so you are supposed to use trig

cinder basalt
#

This was the example question

#

That’s similar to it

wise jasper
#

Ok

cinder basalt
#

Yes

wise jasper
#

Gimme one sec

cinder basalt
#

Okay

wise jasper
#

I'll draw a figure

cinder basalt
# cinder basalt

By the way, here the example question says west but the actual question im doing says south

wise jasper
#

The west and south don't really matter

#

The only important part is the angle

cinder basalt
#

I’m not entirely sure actually if it’s important

wise jasper
#

Could be better, but should suffice

#

Ok

cinder basalt
wise jasper
#

Do you know the trig ratios?

cinder basalt
#

Sohcahtoa

#

?

wise jasper
#

Ye

#

What side do we know?

cinder basalt
#

yes is it cosine to use

wise jasper
#

Ok

#

gj

cinder basalt
cinder basalt
wise jasper
#

Oh wait the drawings wrong

#

gimme a sec

cinder basalt
#

Okay

wise jasper
#

That side is 27km

cinder basalt
#

Ohh

wise jasper
#

So we have opposite

cinder basalt
#

so we need to find the hypotenuse

wise jasper
#

We want hypotenuse

cinder basalt
#

sine

wise jasper
#

Sin of what angle

#

(measure)

cinder basalt
#

148-90?

wise jasper
#

Which is?

cinder basalt
#

58

#

27/sin(58)

wise jasper
#

so $\sin(58^\circ) = \frac{opp}{hyp}$

clever fjordBOT
#

Dork9399

wise jasper
#

oh wait mb u alr got it lol

#

so what is 27/sin58

cinder basalt
#

I got 27.194

wise jasper
#

,w 27/sin(58 deg)

cinder basalt
#

oh

wise jasper
#

Thats radians

cinder basalt
#

oh is that wrong

wise jasper
#

There are two angle measuring systems

cinder basalt
#

would it be different on my calculator

wise jasper
#

Radians and degrees

cinder basalt
#

ohhh

wise jasper
#

you can change your calculator back and forth

#

Anyway

#

The distance is about 31.837

cinder basalt
#

Yes

#

So now we divide by time?

wise jasper
#

*speed

#

we want to find time

cinder basalt
#

so

#

wait lemme write this

#

divide by 6.7

#

I got 4.06

wise jasper
#

and we can recalculate sin(58) so that we wont make a mistake because we rounded

#

,w 27/(6.7 * sin(58 deg))

cinder basalt
#

im confused because

#

When I did 27/sin58

#

I got a different ans

#

Even on my calculator rn

wise jasper
#

just do sin(58)

#

tell me what you get

cinder basalt
wise jasper
#

Your calculator is set to radians as well

cinder basalt
#

oh

wise jasper
#

Try pressing mode and see if you can change "rad" to "deg"

cinder basalt
#

Okay

#

ohh I did it now

#

How do I know if it’s supposed to be in radians or degrees

cinder basalt
wise jasper
#

Yes

cinder basalt
#

Thank you so much

#

I understand now

wise jasper
clever fjordBOT
#

Dork9399

wise jasper
#

If you don't then its radians

cinder basalt
wise jasper
#

ah i see

paper moth
#

can anyone help me with this, is it possible to do by using the x^2 + y^2 = r^2 formula?

paper moth
#

you have tell whether the statement is true or false

paper moth
#

how?

summer river
paper moth
#

5

#

units

summer river
#

so

#

what's the radius

paper moth
#

5

#

units

summer river
#

plug it in

#

x^2 + y^2 = 25

#

now is (6,8) inside the circle?

paper moth
#

how do we find that?

#

do i put x as 6 and y as 8?

summer river
#

you can graph it

summer river
#

to see what circle it would be at

paper moth
#

i have to uuse the non-graph method

summer river
#

like

paper moth
#

green one

summer river
#

and the radius is greater than the red one

paper moth
#

but i have to solve without graphing

summer river
#

so like

summer river
#

you can find the radius

#

using calculator

#

√(8^2 + 6^2)

paper moth
#

why square root

summer river
paper moth
#

radius of the green circle?

#

wait

#

so before i got 84=25

summer river
paper moth
summer river
paper moth
#

triangle?!

summer river
#

it's a triangle with base 6 and height 8

#

so c^2 = 6^2 + 8^2

#

c = √(6^2 + 8^2)

paper moth
#

so square root of 84

summer river
paper moth
#

oh whoops

#

yes so 10

summer river
#

10 > 5

#

so does it lie outside of the circle or nah

paper moth
#

what does that mean

paper moth
#

wdym

summer river
paper moth
#

ye ik that but what i am i supposed to use that info for?

#

like if greater does it mean it lies outside or smthing?

summer river
#

if you have a point on a circle of radius 10

#

it's going to be outside a point on a circle of radius 5

paper moth
#

so basically we just found the distances between the points and compared them

#

to find out whether it lies on the circle or not right?

paper moth
#

can you help with this one as well

#

@summer river

#

<@&286206848099549185>

mystic saffron
#

Hey can anyone help

paper moth
#

bruh

#

take another channel

#

this one is occupied

summer river
paper moth
#

thanks

#

and also befor that

#

prove whether true or false

summer river
paper moth
#

sqr root of 26

#

and also can we solve using the formula

#

x^2+y^2=r^2

#

so it is 32 is not equal to 36 so it is false?

Query regarding vector spaces..

#

The vector obtained by plugging values into say property 7, does it need to satisfy the original condition?

#

Taking this question as example; if we take values of u,v which satisfy x+y+z=0

#

does c(u+v) also need to satisfy x+y+z=0?

wooden python
#

because no, you don't -- assuming axioms 1 and 6 are satisfied.

fallow saffron
#

I know that we need to verify c(u+v)=cu+cv

#

solving both sides would give us a vector, LHS = RHS means that the property is satisfied, but I'm just curious whether the obtained vector needs to fulfil the original condition which applies to u,v i.e x+y+z=0

#

If yes, does it extend to other properties as well? Does the zero vector need to satisfy x+y+z=0 as well for the set to form a vector space?

wooden python
fallow saffron
#

Implying that the results from 2,3,7,8,9,10 don't need to lie in V?

#

LHS=RHS is sufficient

severe veldt
#

help pls

fallow saffron
#

Occupy a new channel por favor 🙏

sharp oak
#

c(u + v)
And
cu + cv

Need to be the same vector.

Note that you have this for free, because this holds for all members of R³, not just the ones where x + y + z = 0

fallow saffron
#

but the vector which is c(u+v) or cu + cv doesn't need to lie in V, right

sharp oak
#

Well, u and v are in your space, so u + v must be as well, by def 1.

Likewise if u + v are in there, c(u + v) is, by def 6.

#

So yes, if u and v are vectors such that x + y + z = 0, then it must be the case that c(u + v) is also such a vector.

fallow saffron
#

The same applies to property 8.9?

sharp oak
#

Note that property 7 played no part in my derivation

#

So I'm not certain what you want to show about 8 and 9

fallow saffron
#

my query was just that

#

for the LHS=RHS conditions / properties

#

whatever resulting vector is obtained from it

#

does it need to lie in V i.e fulfil the condition which is x+y+z=0 in this case, for V to be a vector space?

sharp oak
#

If u is a member of the vector space, then (c + d)u is as well

#

By def 6

#

(cd)u is as well

fallow saffron
#

like if c(du) was not satisfying x+y+z=0, would V still be a vector space?

#

oh

sharp oak
#

As yes, we would need (cd)u to be a member, if u is.

fallow saffron
#

ah alright, so we don't need to bother checking that since u,v lie in V

#

but that's only for the given condition which is a rather convenient one (x+y+z=0)

#

makes sense I suppose. Thank you for your time and assistance.

how do i get g(g(x))

odd edgeBOT
mystic saffron
#

i got somewhat like this but idk how to simplify it

trim matrix
mystic saffron
#

the final answer is -1/x

mystic saffron
trim matrix
#

just simplify

mystic saffron
#

i tried but i prob did sm mistkaes i cant get the answer

trim matrix
#

what does $\frac{x-1}{x+1} - 1$ simplify to?

clever fjordBOT
mystic saffron
#

i genuinely have no idea how to simplify that. my bad

trim matrix
#

can you simplify $\frac12 + 1$?

clever fjordBOT
mystic saffron
#

i'd use calculator which is 3/2

trim matrix
#

you can't do it by hand? : |

mystic saffron
#

uhm

#

so thats my problem isnt it

trim matrix
#

indeed, it is

mystic saffron
#

wait

#

hmm

#

isnt it like

#

cross mutiply

#

multiply

#

and then add

#

i dont rlly rememebr it

trim matrix
#

alright, let's learn how to add fractions

#

let's say you have two fractions $\frac{a}b$ and $\frac{c}b$

clever fjordBOT
mystic saffron
#

yes

trim matrix
#

they both have the same denominator, right?

mystic saffron
#

yes, b

trim matrix
#

let's add them.
$$ \frac{a}b + \frac{c}b $$
This simply evaluates to $$ \frac{a + c}b $$

clever fjordBOT
mystic saffron
#

i see

trim matrix
#

the rule is this: if two fractions have the same denominator, we can add the numerators and divide by the denominator

mystic saffron
#

got it

trim matrix
#

time for an exercise. simplify $\frac{1}3 + \frac23 + \frac33$

clever fjordBOT
mystic saffron
#

thats just gonna give ((1+2+3)/3) sorry idk how to use the texit bot

trim matrix
mystic saffron
#

6/3=2

trim matrix
#

very good

mystic saffron
#

what if theres variable

trim matrix
#

we're gonna come to that

mystic saffron
#

okay

trim matrix
#

now, let's try and add $\frac{1}2 + \frac{1}4$

clever fjordBOT
mystic saffron
#

wait

trim matrix
#

we don't have same denominators now, do we?

mystic saffron
#

nope

#

but

trim matrix
#

yes?

mystic saffron
#

this is how my elementary teacher taught me 😭

#

i dont mind if u wanna teach another way

trim matrix
#

what he taught you is an algorithm

#

what i'm gonna teach you is what goes under the hood

mystic saffron
#

oh woaw

#

okay

#

sure

trim matrix
#

alright now..

#

multiplying a number by 1 doesn't change anything abt it, yes?

mystic saffron
#

yes

#

correct

trim matrix
#

let's write that sum differently. $1\cdot\frac{1}2 + \frac{1}4$

clever fjordBOT
trim matrix
#

i multiplied the first term by 1

#

do you think that changes the sum?

mystic saffron
#

no

#

dont think so

trim matrix
#

indeed it doesn't. because multiplying by 1 does nothing to a number

#

now... what does $\frac{2}{2}$ simplify to?

clever fjordBOT
mystic saffron
#

just 1

trim matrix
#

what does $\frac33$ simplify to?

clever fjordBOT
mystic saffron
#

also 1

trim matrix
#

what does any $\frac{a}{a}$ simplify to, if $a$ is any number?

clever fjordBOT
mystic saffron
#

its also 1

trim matrix
#

very good

#

that means $1 = \frac22 = \frac33 = \cdots = \frac{a}{a}$, right?

clever fjordBOT
mystic saffron
#

woah

#

yes

trim matrix
#

let's get back to our sum

#

$1\cdot \frac{1}2 + \frac14$

clever fjordBOT
trim matrix
#

we want a 4 under the first term, right?

#

so we can add the two fractions?

mystic saffron
#

do we multiply by 2

#

for both numerator and denominator

trim matrix
trim matrix
mystic saffron
#

i see

trim matrix
#

so it becomes $\frac22\cdot \frac12 + \frac14$

clever fjordBOT
trim matrix
#

which becomes $\frac{2}{4} + \frac14$

clever fjordBOT
mystic saffron
#

ahh

#

right

trim matrix
#

now we can add the usual way

mystic saffron
#

and we have the same denominator

trim matrix
mystic saffron
#

which is 4/3

#

i mean

#

3/4

trim matrix
mystic saffron
#

wow that was easier

trim matrix
#

now let's work with letters

#

okay no.. let's do another example

mystic saffron
#

uh ohh

#

okay

trim matrix
#

let's add $\frac12 + \frac13$

clever fjordBOT
mystic saffron
#

wait wait what

trim matrix
#

what whole number can we multiply 2 by to make it 3?

mystic saffron
#

dont think so

#

wait

#

1.5

trim matrix
#

indeed, there's none

trim matrix
mystic saffron
#

oh

#

i see

trim matrix
#

can we multiply 3 with any whole number to make it 2?

mystic saffron
#

nope

trim matrix
#

let's see.. what number do 3 and 2 both divide?

mystic saffron
trim matrix
#

can you think of such a number?

mystic saffron
#

i cant

trim matrix
#

what about 6?

mystic saffron
#

oh

#

6/3?

#

and 2

trim matrix
#

indeed

#

6 divides both

#

in general, the product of two numbers is always divisible by those numbers

trim matrix
#

now let's back to our sum

mystic saffron
trim matrix
#

$\frac12 + \frac13$

clever fjordBOT
trim matrix
#

we want to make the denominator the product of the two denominators

#

what do we multiply 2 by to make it 6?

mystic saffron
#

3

trim matrix
#

very good. so it becomes $\frac36 + \frac13$

clever fjordBOT
mystic saffron
#

2 times 3 and 3 times 3??

#

oh

#

nvm

#

numerator and denominator

trim matrix
#

indeed

#

and what do we multiply 3 by to make it 6?

mystic saffron
#

oh

#

OHH

#

OHH

#

I SEE WHERE THIS IS GOING

#

3 TIMES 2

trim matrix
#

indeed

mystic saffron
#

2/6

trim matrix
#

$\frac36 + \frac26$

clever fjordBOT
mystic saffron
#

((3+2)/6)

trim matrix
#

now we can add it the usual way

mystic saffron
#

5/6

trim matrix
#

indeed

#

now.. time to introduce letters

mystic saffron
#

ohno

#

lets see

trim matrix
#

let's add $\frac{a}b + 3$

clever fjordBOT
trim matrix
#

what are our denominators?

mystic saffron
#

uhhhhhhhhhhhhh

#

b

trim matrix
#

b and?

mystic saffron
#

1

#

b and 1

#

denominator

trim matrix
#

indeed

#

what number is divisible by both b and 1?

mystic saffron
#

uhm

#

issit 1

mystic saffron
mystic saffron
trim matrix
#

do you know what it means for p to be divisble by q?

mystic saffron
#

q/p ??

trim matrix
#

it means p/q is a whole number

mystic saffron
#

oh

#

p can be divide by q

#

and the answer will give a whole number

#

is what it means

trim matrix
#

what is the produc tof x and y?

mystic saffron
#

does that mean both x and y is divisible by k

trim matrix
mystic saffron
#

so its like k/x and k/y

trim matrix
#

now, tell me, what's the product of x and y?

let's do this again

mystic saffron
#

isnt any number is divisible

#

by those

trim matrix
#

The product of two numbers is divisble by both of those numbers.

#

What is the product of b and 1?

mystic saffron
#

its

#

b

trim matrix
#

very good

#

then what number is divisble by both b and 1?

mystic saffron
#

whic means

#

both b and 1 is divisible by b

trim matrix
mystic saffron
#

:sOB

trim matrix
#

it means b is divisible by both b and 1

mystic saffron
#

wait

#

let me

#

oh

#

ok

#

okay

#

the product of two number is divisible by both of those two numbers and in this case the product is b and the two numbers is b and 1

#

FINALLY

#

😭

Question - I'm creating an AI logic in a traffic simulation to have cars detect their closure rate speed. Basically I need a value of Car1's distance to Car2 and how quickly the value is dropping for each calculation. What is the best formula to achieve this?

abstract shell
#

I've figured out the cars distance. But only need to figure out how to calculate the speed in which the distance is dropping.

leaden karma
#

what other information do you have about the cars?

abstract shell
#

Their speed in mph is available.

#

For both cars.

#

So their distance from each other and speed is available.

#

Currently I don't have the logic of direction the vehicles are, to see if they are facing each other or away from each other, but I can set this up. Would this help?

frigid canopy
#

if you know their directions you could find their relative velocities

abstract shell
frigid canopy
#

and based on their relative velocities you could find the distance between them

frigid canopy
#

In that case I'm not too sure, sorry

No worries, thanks for the suggestion.

This is the step by step walk through for part of a problem in my textbook, but I can't figure out how the last two steps happened

wet raven
dusty fern
#

That I could get

#

What I can't get is line 4

#

And from there to b-2

wet raven
#

Thats just a factorization

dusty fern
#

I understand factoring out 10

#

Wait

#

My bad, I wrote the problem wrong

#

Still stuck on the last part though

#

I don't think x+10b-10 factors

#

Unless I split it up....

#

Then I'm still stuck with x/10 + b - 1

#

Oh but x=-10 so that becomes a 1 as well

#

Just ignore me.
