So I am dealing with perlin noise in unity
I just have to add an x and y coordinates and unity returns a float that determines how dark or bright a pixel is
Now, i have a slider that would zoom in and out of the texture
The problem is that, making said texture bigger or smaller will also zoom
"newScale" Was something I tried that didnt work
What should I add to the coordinates to make it so when the texture gets larger or smaller it will give me the same exact texture but in higher definition?

why is the slope of a line defined as y2-y1/x2-x1?
why is it not m = x2 - x1/y2-y1 or something else
@abstract scaffold
abstract scaffold
we just conceptually defined slope as rise/run instead of run/rise. it makes more sense that way.
especially with derivatives. speed = distance/time
median trail
it's just that I'm trying to understand what slope means since rice/run doesn't make sense to me
I'm trying to get the concept by using triangles, their similarity and assuming m is a proportionality constant, but I don't understand why I would use y2-y1/x2-x1
abstract scaffold
slope is defined as rise over run. with this we can generalise it (not fixed at some origin/axis) {if rise/run can't be easily found}
median trail
but okay, if I define m = y2-y1/x2-x1, then what can I do using this? what special property of geometry I can use by defining it this way?
abstract scaffold
if you run at a constant rate of one unit to the right, if you rise y units up, the more y increases, the more taxing it is just to "run one unit to the right"
slope is just general. could be as simple as just figuring out how steep a hill is.
or you can use it to assist you into introducing derivatives.
using the other definition m = tan(theta)
you can see the bigger theta is, the steeper the slope becomes.
median trail
hmmm let's say I have two points A(2,3) and B(5,4), so the slope of the line between those two points is 4-3/5-2 = 1/3 = m
and let's say y = (1/3)x
so, for every x I plug into that formula I get the corresponding y value, would it be correct to say that x and y correspond to the the sides of a right triangle?
I'm gonna draw this for you to understand what I mean
I just want to understand why I would define m that way and what it means to use that formula
abstract scaffold
y can't equal (1/3)x, it needs to be shifted as well btw.
you can use the gradient as a locus to generate a "general equation of a straight line@
=tex m = \frac{y - y_0}{x-x_0} \
y - y_{0} = m(x-x_{0})
rotund pawnBOT
median trail
the only thing I get with this definition is that every time I choose an X, I get a Y that will make m stay constant
abstract scaffold
ah. i think i see what ur trying to do. i'll try to show similar triangles.
median trail
yeah
by using this definition I generate all kinds of similar triangles; therefore the X and Y stay in the same line
But what's the connection between a line, slope being constant and m = y2-y1/x2-x1?
abstract scaffold
tan(theta) = y2 - y1/x2-x1
pero tambien
tan(theta) = y4-y3/x4-x3
o sea
son triangulos semejantes, asi que
(y2 - y1)/(y4-y3) = (x2-x1)/(x4-x3)
=> y2-y1/x2-x1 = y4-y3/x4-x3
slope being constant, we can define steepness this way, and it just helps.
median trail
and what's the tangent of a triangle?
abstract scaffold
defined as opp/adj
it works out because this coincidentally becomes the tangent of the unit circle definition of trig.
median trail
Hmmmmm this?
median trail
and where/what is the tangent in your graph?
abstract scaffold
if i drew a unit circle separately, then i can show it's tangent.
I have to shift the ratios such that x2-x1 is one.
on the unit circle, the tangent(opp) divided by adj (radius 1 unit circle) ends up giving the same as the triangle definition opp/adj
median trail
oh what if x2-x1 = 3 or something? how do you change the x2 - x1 to one?
oh by using similar triangles?
median trail
My brain is trying to process what's going on because this is very impressive to me
abstract scaffold
if i rotate the triangle in the same as as this, then it'll look like this.
median trail
this is very cool
abstract scaffold
yes
median trail
thank you 🙇♂️
when we calculate tan(tetha) it's the value of the tangent of the unit circle that's also the tangent for every other triangle of the line if we stretch or expand the unit circle, right?
or is tangent only used when talking about the unit circle?
abstract scaffold
well. on the unit circle. it is exactly the length of the tangent line from x axis up to the secant.
on other cricles, it becomes opp/adj
where opp is still the tangent line.
median trail
I could even define my own slope as m = sin(tetha) but it would be harder to calculate, right?
tan(tetha) is better because I can use X and Y
abstract scaffold
i guess you could... but then that would change definitions of other things in maths. so yeah tan is more superior as it just works out nicely afterwards
like it makes more sense to say a slope can just keep increasing or decreasing forever rather than being capped at [-1,1]
oh yeah. with sin(theta) u have problems... is a vertical line +1 or -1?
well. i guess tan(theta) has that problem as well, depending on if you approach 90 degrees of -90 degrees.
it makes more sense to use tan() as it signifies more of the rate of change we're used to such as speed/velocity/accelration
median trail
it's cool to understand why concepts are the way they are 😊
I have another question, when we find the derivative at a point, then it gives you the slope as if the coordinate system was centered at that point?
abstract scaffold
yeah. slope of the tangent at that point.

@abstract scaffold when we find the derivative of a function say f(x) = x^2, we are not getting the slope of a tangent line at a certain point, so what does this represent?
gusty ermine
The function f(x) = x^2 is a parabolic curve.
So the tangent to the curve is of equation y = 2x, found by taking derivative of the given function f(x)
median trail
hmmmm
gusty ermine
So what's your doubt there @median trail ?
median trail
So, is 2x tangent to each point of the graph x^2?
i just dont know what it represents besides a tool to help you find the derivative at a certain point
gusty ermine
Hmm let's see
Yes, 2x is a tangent to each point of the graph of x^2
Okay, now the derivative of a function is the tool to find out the monoticity of the given graph/function.
Monoticity talks about whether the graph is increasing or decreasing in nature.
Or is it neither increasing nor decreasing.
Shall I explain it with the graph x^2 @median trail ?
Welp.
In case of the graph x^2, the derivative/tangent is 2x
Now, input some real values in y = 2x
Let's say -
x = - 15, y = 2(-15)= - 30
Now, let's take 2 more numbers.
If x = 0, y = 2(0) = 0
If x = 5, y = 2(5) = 10
We can see here that
When we increase the input value of x, the output value of y increases
median trail
the only thing I do not understand is that we have a formula that represents the slope of the tangent line at any point
if we plot both graphs, 2x doesn't look that special like it just touches x^2 once and that's it
so, how come 2x represents the slope of the tangent line at any point?
gusty ermine
No, 2x represents a tangent which is a straight line to a point on the curve of x^2
Hmm so what's the problem?
By the way, the slope of the tangent is 2
I guess, you were asking about that 😆
2x represents the tangent line.
And the slope of the tangent line is 2
Just 2
median trail
I guess, you were asking about that 😆
@gusty ermine no
I just don't understand how we can find the slope of the tangent line at any point using the same formula
gusty ermine
Okay
The slope of tangent is found by looking at the equation of the tangent line itself
So when you look at equation of line y = 2x
You see a general equation of y = mx + c
Compare the two equations here @median trail
What's the value of m and c in equation y = 2x?
median trail
c? m = 2
gusty ermine
Right
You can't see the value of c because it's equal to 0 in y = 2x
A standard linear equation is represented as y = mx + c
Where m = slope of the line and c = y-intercept made by line on Y-axis
So if m = 2
That's the slope of tangent line y = 2x
median trail
gusty ermine
Look at the graph
still radish
what is x
gusty ermine
X represents the input value in the function
gusty ermine
Or in graphical terms, it takes the values on the X-axis on 2D graph.
median trail
I just don't understand why we can describe the slope of the tangent line at any point using just one formula 
gusty ermine
5 = 10?
@still radish no, 2(5) = 2x5 = 10
still radish
gusty ermine
I just don't understand why we can describe the slope of the tangent line at any point using just one formula
@median trail oh the general representation of y = mx + c?
We can describe the slope of a line through other methods too.
For that you might need at least two points through which the line passes
gusty ermine
Yes?
median trail
I mean how is the slope of the tangent line at every single point of the graph x^2 just by using 2x
why this formula doesn't change at any single point of the graph x^2
gusty ermine
So your question is - why doesn't equation of tangent line 2x changes at every point on the graph?
median trail
yes
gusty ermine
Means why does it stay the same goddamn way?
You see, the tangent can't change because it tells the nature of the graph.
The graph has a nature.
It follows that nature with the mathematical relation of y = x^2
So this tangent represents that unique nature of the graph
gusty ermine
That the rate of change of this graph, means the tangent/derivative, is uniform in nature
Tangent just screams the property of a graph
A graph has one nature (whether it is increasing, decreasing or neither of those)
@median trail you can watch a khan academy video on tangent/derivative
Or maybe ask a math teacher about it to explain you more

@median trail la derivada de la función f(x) sí representa el valor de la pendiente del tangente en el punto "x" (o sea, cualquier punto x).
podemos describir la pendiente del tangente en una fórmula por la definición de la derivada usando los límites (la cual con "h" , la otra definición describe la derivada en un punto específico)
la derivada de x^2 es igual a 2x
la pendiente en x=0 es 0
x=1, m = 2
x=2, m = 4
x=4, m = 16
median trail
interesting, I just can't wrap my head around this haha it's so hard to understand why it holds for every single point in the graph

=tex \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}
rotund pawnBOT

es así gracias a esa definición hacia arriba
median trail
maybe this is something that requires a deeper knowledge in math, it's not very clear for me why that definition spits out the same result for every single point 😅
I'm trying to understand this graphically what this means
(the fact that the slope of the tangent line is the same at every single point)
abstract scaffold
la pendiente no es la misma. está subiendo linealmente (si es un polinomio de grado 2)
la pendiente sí es la misma si es una recta

median trail
@abstract scaffold I mean the formula is the same
abstract scaffold
pues, sí el límite existe, sólo va a haber "un resultado"
se puede elegir cualquier x. en este caso, parece que se elegió x=1 para demostrarlo
e.j, cuando x = 1 y h = 4, x+h = 5
f(1) = 1, f(5) = 25
=tex \implies m = \frac{f(5) - f(1)}{5-1} \
\implies m = 6 \text{, una aproximación}
rotund pawnBOT
abstract scaffold
se puede elegir una h muy pequeña para aproximarla más.
y para cada x, es así.
=tex \frac{d}{dx}({x}^2) = \lim_{h \to 0} \frac{(x+h)^2 - x^2)}{h} \
= \lim_{h \to 0} \frac{(x^2 + 2xh + h^2) - x^2}{h} \
= \lim_{h \to 0} \frac{2xh + h^2}{h} \
= \lim_{h \to 0} \frac{h(2x+h)}{h} \
= \lim_{h \to 0} 2x+h \
= 2x + 0 \
= 2x
rotund pawnBOT
median trail
interesting so the explanation is just that when the limit approaches 0 at any point of f(x) then the limiting value follows the same formula for any x
abstract scaffold
si, cuando h->0, el resultado es asi
median trail
when we plug 0 in limits we mean "this is such a small value that we don't really have to care about it"?

ankiapp is fake, they really need to change their name and stop stealing users. It's fine that they can import Anki decks, just don't use the same name. The subreddit gets support requests for missing features because of this rip-off.
quizlet can only handle four boxes worth of image occlusion at a time, even if you give it more boxes: Which state is California? only covers four states but not the state you thought it was. In that case you should've gotten it wrong, but by limiting the answers in the interest of making it relatable for people who only understand multiple choice, you get a second chance to get it right.
Duolingo and Memrise both suffer from an inability to mix due cards. You have to visit every subject for it to remember you actually had to study it.
Use either Anki or Supermemo and stick with it for the rest of your life.
Also in case anyone stumbles upon it, it's not legal to use Brainscape.

Their terms of service are a copyright infringement trap, against how the main page appears

it's illegal because it is too effective for language learning
people were becoming native in 3 days
and it wasn't fair to everyone else
low mesa
If you create Anki flash cards from a school book you bought (say, including a diagram) and sync it to your other device, the intermediate backup copy on the web is still a private copy. If you share a deck, then it becomes a public copy, and that's when you need to make sure you're allowed to share that content. With Brainscape, they don't make that distinction. Everything you upload, you must have the rights to.
This isn't as important, and applies to other websites as well, but it's a walled garden: Buying a commercial deck locks you into using their service, you're not allowed to export it to another app.

(jk it’s pretty cool and I use it often)
Though maybe a user interface uplift for the mobile app would be nice
Also an easy way to practice cards by seeing the back instead of the front first for an entire deck of cards without having to individually select each card
It seems that’s the only way to do that... though maybe I’m wrong
