The way to find c in this case is to use the product and the constants given by (n+1)! and your (x-x_k)
warm brook
then what does the other one do
xi is just another variable in the application I used there. In this part of numerical analysis, it's used as an arbitrary value to describe the exact error in polynomial interpolation
warm brook
Yes, tbh zeta can be named anything, but it was just chosen with that variable for whatever reason
It's just conventional

someone needs to right a book full of these weird functions and there nmes as well as what they do

if ink_left/max_ink == 1 and paper_left/max_paper == 1 then it will return max_print_amount

alpine sable
yes
warm brook
yes
Then yes, c1 and c2 will be 0
A way to think about this so you don't have to solve the first order system is just that this is after all of the exponential terms have effectively reached 0, so it makes sense that the differential equation solution is 0
so you're just left with the particular solution
alpine sable
ok so I used Acos(2t) + Bsin(2t) as the ansatz for the particular solution
$$x(t) = -\frac{3}{17}\cos\left(2t\right)-\frac{5}{17}\sin\left(2t\right)$$

Can someone like explain to me
Why the ^-1 is the inverse
Is it because it’s the reciprocal?
agile torrent
its not reciprocal
its inverse function of tan x
in case of tan, you get a ratio for a particular angle
but in tan^-1 you get the angle as result for a particular ratio
daring roost
But what does -1 do
Compared to normal
Like why is the -1 do
Could you convert it into 1/tan(x)
warm brook
no you can’t, it’s a problem in notation i suppose, but typically ^-1 attached to a function means the inverse. hence why arctan is also the inverse of the tan function
so $f^{-1}(x)\ne (f(x))^{-1}$ is what i mean by that. the left side is the inverse of $f$ and the right side is the reciprocal of $f$

Three ants are located at the corners of an equilateral triangle ABC. The triangle has sides of length 1m. Ant A starts walking towards ant B, ant B starts walking towards ant C and ant C starts walking towards ant A. All the ants walk at a speed of 1cm/s. If the ants keep walking towards each other, will they ever meet? If so, where, and after how long in metres or centimetres?
quaint trout
Convert to the same unit first
Then just write it as a fraction and simplify
the one is in cm, the other is in m
Write them both in cm
Or both in m
Do that first
What did you get?

3m and 3cm are not the same
How many cm is one m?

austere obsidian
The sequence of partial sums here is unbounded so does not converge to any L
But it seems that the value we add gets smaller
so why not the sum approach a particular value?
quaint trout
Because of the definition of convergence of series
It converges to a value if the sequence of partial sums gets closer and closer to that value
That's the defn
That does not happen here
The partial sums here can get arbitrarily big and is unbounded
alpine sable
can i ask sumthing
i'm dumb at math need to understand something about linear equations
3x + 2x × x = 12
Is this a linear equation? Cuz if we add the expression first than multiply the variable we'll get the value of x as square
But if we multiply any of the expression with the variable x first it'll not be possible to add the other expression later cuz the value will change to x² and we can't add two expressions with different variables 😀
can sumone explain that
n y
verbal ermine
placid zinc
You can add x and x².
For example, 3 + 9 = 12
However, there's no nice way to simplify x + x²
It's not linear because there's no y (or, there's no input/output)
And there's an x²

Hess' law will allow u to add enthalpies as they are state functions lol

it lasts for a short time whilst allso producing high intensity light

im not too sure as im not that much of an expert on this, but i remember our teacher talking about something related tothis
gilded turret
i read this but i dont get how it being "extremely exothermic" makes it difficult to measure

the fact that its extremely exothermic implies that theres ALOT of energy given awsay from the reaction . This happens really quickly as well hence making it hard to measure

you're not measuring any force when you measure mass
when you measure weight you're measuring the force of gravity based on its mass

look you r mass is the same wheather your on the moon or on jupiter or while floating in space,
BUT
your weight isnt
glass lichen
mass: the amount of shit in the object

sacred sapphire
are you the troll guy?
so hear me out. firstly For a force to exist need not mean there is motion.

Does space have mass?
sacred sapphire

depending on the normal force experienced by the object

sacred sapphire
question:
red ledge
nope, but we can see their impact
U mean u can see the result? U can't actually see an imapct!
glass lichen
The honest answer is they're just a mathematical object to explain motion
sacred sapphire
what grade are you im just curous, you dont hae to answer if you dont want to
red ledge
By imapct u mean what the forces did which is the result
glass lichen
yes
example the force of gravity pushes things down towards the center of the earth/body
(or pulls them, I digress)
Friction impedes motion, Normal force keeps objects on the surface they're on
etc
red ledge
example the force of gravity pushes things down towards the center of the earth/...
But how come the force of gravity be that way? To push them down flawlessly to the center?
I mean what makes it this perfect?
glass lichen
That's just how gravity works, there's an attractive pull b/w the planet and the object
red ledge
Like how it controls it? I mean it's non a living entity or something
glass lichen
cause it's a function of mass
and distance the object is from the center
$\abs{F_g}=\frac{GMm}{R^2}$
red ledge
cause it's a function of mass
What is a function of mass?
ocean sealBOT
Mosh
red ledge
I mean why it's always down to the center?
sacred sapphire
observation
glass lichen
cause we model everything as point masses.
red ledge
I mean there is a reason
glass lichen
Physics is just a model to explain phenomena, it's not a set in stone rulebook for the world
sacred sapphire
a process of trying to match theory with observation
red ledge
Okay how do we know that specifically this force is gravity? And how do we know that gravity is what pushes things down and not like an effect of gravity..
glass lichen
...
red ledge
What made us so sure that graivty is one singluar force?
glass lichen
put something in a vacuum and let it drop
only force is gravity, and the object fell
so gravity pulls downward.
red ledge
Okay Mass shouldn't be a force, but if it remained or became this way then it's a force since it keeps the object from changing
But if mass changes! then the object would be effeceted
Therefore, mass is a force
sacred sapphire
you would have learnt this in school?

Mass isn't what makes gravity?
Just because gravity changes! Doesn't mean the mass was the reason that made it change!

rapidly changing topic (admittedly to my benefit)
(see eq below)
wolfram alpha gives a real solution as smth and an integer solution as a=3, b=3, how would I mathematically arrive at the integer solution? I admit the algebra is a bit scuffed because it stems from 2+sqrt(3) = (sqrt(a)+1)/(sqrt(b)-1) and I just messed around w it until I got the above, but unsure of how to proceed

Ahhh yeah I'll try that too - I'd tried rationalising the denominator when it was in its previous form but that didnt help much
sacred sapphire
yeah
astral latch
got it to the current state to try and move the variables to one side and constants to another
its rly weird tho, cus symbolab gives the real solution too - only wolfram alpha gives both the real and integer solution
red ledge
Exactly! Neither to anyone asking here, U are just here trolling and interrupting. which isn't the purpose of this channel.
Cause u are a troll, U didn't answer.

for what its worth, for an integer solution both a and b are 3, so ofc if you just replace either of them with the same variable or have the prior knowledge that a=b then its piss easy n everything cancels out

Probably better off asking in like abstract algebra

The question does say use an addition or subtraction formula, so it did work through into tan 30 +45 which simplifies into 2+sqrt(3)

so ur saying that i need to find the reason why i see the limits so hard , right?

The answer is f.
You can say so, since you split 50 hours into at least 2 days.
In 24 hours, it'll be 9:00 AM.
Then 24 hours again, we get 9:00 AM.
Finally add two hours, since 50-48=2.
