What do I do with the 6/3
#help-0
oak chasm
@plucky crow So, we'll go clockwise 90 degrees to get due east. Then we'll add another 90 to get due south. Then we'll add another 90 to get due west. Then we'll add 90 - 15.5 to get the angle.
plucky crow
oh
oak chasm
Do you see how I got that?
oak chasm
Yes, but do you see how I start out north and start going clockwise?
plucky crow
yeah
oak chasm
I get to due east, then due south, then due west.
Do you see why I went an additional 90 - 15.5?
plucky crow
yeah
oak chasm
Where does the 15.5 come from?
plucky crow
its 15.5 west from north
oak chasm
Right.
plucky crow
okay so the section shaded blue has two radiuses
oak chasm
What?
It's a circle, the radius is the same throughout.
Oh, you mean the lines from the middle to the edge?
oak chasm
That diagram is just to show you where the northwestish angle was.
Forget the blue part and the line due east.
Focus on the line that goes northwestish.
oak chasm
Then start at north.
plucky crow
im a bit confused about the method you used
oak chasm
Then go 90 clockwise to get due east, then 90 clockwise to get due south, then 90 clockwise to get due west, then 90 - 15 clockwise to get to that angle.
oak chasm
What other method?
plucky crow
you made the horizontal components = 0?
oak chasm
Yes, because you want to be swimming due north.
So, the horizontal components of the sum of the vectors has no horizontal movement.
oak chasm
No problem.
oak chasm
What is coming from the west?
plucky crow
oak chasm
Yes, the wind comes from the west and heads east, so it pushes your aircraft eastward.
plucky crow
alright
celest wagon
Is it true that a function cant be considered to be an operation if the output can result in something outside of the functions domain? Take for instance the function f(x) = x-1 with the natural numbers as the domain. This function can result in an output that is outside of the domain of the function, and can therefore not be considered as an operation. Am I onto something or is this wrong?
I haven't really found a formal definition to figure this out, so its mostly intuition im thinking with here
formal definition of what an operation is
oak chasm
@celest wagon Yes, it won't be an operation. See https://en.wikipedia.org/wiki/Binary_operation.
celest wagon
Thanks, this is a unary function tho am i right?
oak chasm
Yes, it will still require that you produce an element in the domain as your output.
celest wagon
"More specifically, a binary operation on a set is an operation whose two domains and the codomain are the same set." this is what i needed. Cheers @oak chasm
oak chasm
No problem.
final crag
Can someone explain how this is antisymmetric?
oak chasm
@final crag What definition do you have for antisymmetric?
oak chasm
@final crag Read the top part of this: https://en.wikipedia.org/wiki/Antisymmetric_relation.
Let me know when you've finished.
final crag
Let me know when you've finished.
so i just say that R(a,b) and R(b,a) ---> a=b?
oak chasm
No, I mean, that's one possible conclusion of your proof.
I think it's not antisymmetric.
Is R((1, 2), (2, 1)) true?
final crag
Is R((1, 2), (2, 1)) true?
yes
oak chasm
Is R((2, 1), (1, 2)) true?
final crag
Z×Z. (a, b) is related to (c, d) if a ≤ c or b ≤ d
ocean sealBOT
Chai T. Rex
final crag
what would b be here?
oak chasm
You saw that they had R((a, b), (c, d)), right?
So, b would be the second part of the first tuple.
I also filled it in in the parentheses.
final crag
so 1,2?
oak chasm
No
ocean sealBOT
Chai T. Rex
final crag
so b = 1
oak chasm
Right, b is 1.
final crag
so that statement is false
oak chasm
What statement is false?
final crag
**Chai T. Rex**
this
oak chasm
There's been a lot of statements so far.
ocean sealBOT
Chai T. Rex
oak chasm
**Chai T. Rex**
I already put it that way.
So, R((2, 1), (1, 2)) is true.
R((1, 2), (2, 1)) is also true.
final crag
so that would be 1 <= d(1<=2)?
oak chasm
What?
final crag
**Chai T. Rex**
where did this come from exactly?
oak chasm
Which part of it?
ocean sealBOT
Chai T. Rex
oak chasm
The second part came from filling in b and d.
oak chasm
Are you just guessing on these things or do you plan to use the relation's definition?
What's the relation's definition?
final crag
R(a, b) and R(b, a), then a = b.
oak chasm
No, that's antisymmetric's definition.
What's the relation's definition?
Right. What part comes after the if?
final crag
inclusive or
oak chasm
Of what?
final crag
of a ≤ c or b ≤ d?
oak chasm
Right, so figure out both parts of the or statement.
ocean sealBOT
Chai T. Rex
oak chasm
Then use or on them.
final crag
So our example was (2,1) ,(1,2)
oak chasm
No, on your latest example.
oak chasm
so if u do (1,3)(3,1) isnt it false?
This one.
oak chasm
Why?
oak chasm
less or equal.
oak chasm
Right, but you need a small correction. It's less than or equal, not less than.
final crag
yeah idk how to do that here on keyboard other than <=
oak chasm
<= is fine.
So, what if you reverse those and have (3, 1), (1, 3)?
Is the relation true or false?
final crag
3 <= 1 or 1<= 3 would be true
final crag
yes
oak chasm
(1, 3) = (3, 1)?
final crag
wait but it states "R(a, b) and R(b, a), then a = b."
final crag
Yes because it states then a = b?
oak chasm
I don't care what it states.
final crag
1,3 = 3,1 is not equal to each other though
final crag
so why is it saying then a =b?
oak chasm
Do you know how a logical implication works?
ocean sealBOT
Chai T. Rex
final crag
if and only if?
oak chasm
No.
final crag
oh then, im not sure
oak chasm
Do you see a doubleheaded arrow?
ocean sealBOT
Chai T. Rex
oak chasm
If you have the P, you should also have the Q.
ocean sealBOT
Chai T. Rex
final crag
then it would be true if its false and false?
ocean sealBOT
Chai T. Rex
oak chasm
What about the other three?
final crag
true true is false
oak chasm
No.
oak chasm
If you have the left side true, you should also have the right side true.
If you have the left side false, it's fine.
final crag
ah so false -> true would be true?
final crag
True
oak chasm
What's T -> F?
final crag
True as well
oak chasm
What's the rule?
final crag
left side has to be true
final crag
If you have the left side true, you should also have the right side true.
so this means if left side is true and then the right side has to be true
final crag
If you have the left side false, it's fine.
left side false, right side is true = true
oak chasm
What does "it's fine" mean to you?
final crag
oops
but then wouldnt that mean if you have true on the left side but false on the right side
it would result false?
oak chasm
What's T -> F?
final crag
False false would be true
oak chasm
What's F -> T?
final crag
F -> T would be True
oak chasm
What's F -> F?
oak chasm
Right.
final crag
F is on the left which means its fine
oak chasm
Now, let's go back to the definition of antisymmetric.
$$(R(a, b) \lor R(b, a)) \to a = b$$
ocean sealBOT
Chai T. Rex
final crag
oh i think i see whats happening now
ocean sealBOT
Chai T. Rex
sly mantle
@oak chasm \land not \lor
final crag
so first sstaement is True, 2nd is False?
oak chasm
@sly mantle In the relation definition, it's inclusive or.
final crag
That means its False
oak chasm
@final crag Right!
final crag
jeez
oak chasm
So, if you see "if ... then ...", it's like "... -> ..."
final crag
ur better than my professor teach my class
sly mantle
@oak chasm wdym
sly mantle
i'm not talking about the relation above
oak chasm
@sly mantle Oh! I see what you mean.
sly mantle
what you wrote isn't the definition of R being antisymmetric
ocean sealBOT
Chai T. Rex
sly mantle
yes
ocean sealBOT
oak chasm
No problem.

Does anyone know the answer to this Biotechnology question?
limpid spade
The sum of n terms of AB is the sum(addition) of first n terms of the arithmetic sequence. It is equal to n divided by 2 times the sum of twice the first term – 'a' and the product of the difference between second and first term-'b' also known as common difference, and (n-1), where n is numbers of terms to be added.

I am trying to find out if the series is convergent or divergent and come to the conclusion that is is divergent
Not sure where I went wrong
The entire question for context
I now know it converges (as I can tell by my choice being wrong), but how do I calculate the sum
severe forge
right side diverges clearly right ?
alpine sable
Are you taking about the (-1)^n/3^n?
severe forge
yeah XDµ
muted raft
It is a geometric series.
severe forge
even then it wouldnt help
stray pawn
no zs i just tested that
alpine sable
1/3^n is bigger than (-1)^n/3^n, and it converges, therefore the other also converges
muted raft
tested what
stray pawn
its not geometric series
muted raft
its not geometric series
Why not?
stray pawn
am i wrong? i dont see a common ratio
alpine sable
is this true?
$\\sum_{n=a}^{b} f(n) + g(n) = \sum_{n=a}^{b} f(n) + \sum_{n=a}^{b} g(n)$
ocean sealBOT
Mofumofu
muted raft
Yes this is valid
alpine sable
You can separate them 
stray pawn
yes so break it up into two then you have geometric series
severe forge
isn't the left one a o(1/n^2) ?
alpine sable
oh then that makes it easier
muted raft
and $\frac{\qty(-1)^n}{3^n} = \qty(\frac{-1}{3})^n$
ocean sealBOT
zslya
alpine sable
\qty ?
muted raft
$\qty()$
ocean sealBOT
zslya
stray pawn
oh okay. so it seems you have to break up the summation into two terms. then find the sum of each summation using geometric series formula and sum them up
muted raft
vs $\left( \right)$
ocean sealBOT
zslya
alpine sable
god, i used to do it like this $\left( \right )$
ocean sealBOT
Mofumofu
alpine sable
oh
muted raft
oh okay. so it seems you have to break up the summation into two terms. then fin...
and yes this is correct
alpine sable
left one is o(1/n^2) so it converges
But if this was the case, is the entire series not convergent?
severe forge
depends
stray pawn
you find derivative of f'(x) and plug the point (1, -1) to find the slope
sage lynx
oh alr
stray pawn
then you use point (-1, 1) in formula y = mx + b to find b
sage lynx
cool, i'll do that then get back to see if i got it right
alpine sable
Or I might be confusing the rule that a convergent series stays convergent if something is summed or if it is multiplied by a term
I probably has a misconception here
severe forge
but since the right one is also convergent it converges yes
alpine sable
Got that
So I would separate the summations, find their individual sums, and add them together
Then that would be the value of the original summation
severe forge
wait what are you looking for already ? Lmao
alpine sable

muted raft
haven't studied this so can't help.
severe forge
alright np
sage lynx
you find derivative of f'(x) and plug the point (1, -1) to find the slope
so i got the derivative to be f'(x) = -32x^3+36x^2-12x+1, do i plug in 1 for x and -1 for f'(x)?
bc then there's no variable
or do i add an m or b somewhere
nvm i got it

If by dilate you mean stretch, then you would do f((1/2)(x))

rigid pivot
Is there a way to transform the Fibonacci sequence's formula so that F0 and F1 are not equal to 0 and 1 respectively, but something else I arbitrarily choose?
This formula:
It assumes that F0 = 0 and F1 = 1, but what if I wanted that F0 = 3 and F1 = 7?
severe forge
If you start the sequence from somewhere else you can
But then you had 1 to n in the formula soo
muted raft
Does binet's formula work for arbritary a, b?

scatter plot in question>
this would be no correlation right? x increases as y increases but there is also random dips in the plot
so by that logic it would be no correlation right

correlation exist, but just weak

positive, negative, none??
because i wouldnt be able to tell if its + or none
neon aurora
I'd say positive
quasi sable
kk ill try that
uncut osprey
It's definitely a positive correlation. You can make out a positive slope
The random dips are just slight anomalies in the data likely caused by some form of margins of error

quasi sable
It's definitely a positive correlation. You can make out a positive slope
so scatter plot correlations are defined by the slope the line of best fit has, right?
uncut osprey
You can definitely think of it like that.
I doubt your teacher will be evil and intentionally give scatter data that's really hard to pick out if there's any correlation. But here's a general diagram to help you see the 3 types
Even this has some pretty extreme disparity between the positive/negative points, so if you can see the scatter plot correlations on this you're set.

You need x by itself. That means you need to get the 4 on the other side
To do this you would add 4 to both side

Then from here you would simplify both sides
and that will be your answer

It is the same for this, but now you need there to be an x in one side not two
So move one of the xs to another side
sage lynx
this is just 0 right because the derivative is 2x/e^x = 2(0)/e^0 = 0/1 = 0
i dont think there are any other values of x that work

alpine sable
at 0,2 and infinity
sage lynx
how come?

ah
alpine sable
As exponential grows faster than quadratic, at inifnity it goes to 0
sage lynx
so its 0 and 2 and then dips back down to infinity

It isn't a number we can assign to x

No but f approaches 0 as x approaches infinity

Why the pepe scared
Cos we’re becoming old and no one can save us from the marching of time as death takes us

I wanna go to Columbia
Transfer decisions come out at the end of this month
Kind of specific
Why Columbia
severe panther
I wanna go to brown, the future lies ahead but only surface area determines my future.

I love the environment built inside of Columbia, how friendly the students are and outgoing for their community, the professors are also amazing
Well where are you studying rn
I have a friend that attends there and he sneaked me into his dorm multiple times
severe panther
Also i am considering Swarthmore College.
alpine sable
TO DO WHAT

Well where are you studying rn
Dmed you it 🙂
After Columbia, my top choices are Harvard & MIT
The bubble built in Cambridge is amazing

My dad always says : Learn surface area, attend calculus, pass it- i can’t even pass 5th grade geometry 
alpine sable
Geometry was the hardest math class for me tbh
severe panther
Yeah exactly
alpine sable
Let’s be honest I’m never going to get into MIT😔it’s fine tho imma try anyway
For me Calc 1 is easier than geometry

Let’s be honest I’m never going to get into MIT😔it’s fine tho imma try anyway
You can do it

3 divided by 2 is 1.5
rugged lynx
so the bigger number first or what
rugged lynx
<@786396522475552768> what grade u in

I will admit, that tripped me up in the beginning
muted raft
I mean you have a parabola, so integral would probably be the fastest way to calculate the area here?
Its gonna need more context than just this.

You could do it the Chad way: manually divide the parabola into rectangles and calculate the area one by one for years until you die

Hey guys for question 9)a) I don’t know where the right angle is I’m triangle ATB
like how do I even know that it is right angled
woeful pulsar
triangle ATB is probably not right angled
tribal geyser
Th answer says it is
tribal geyser
That’s how a) is 400cos52
woeful pulsar
calculate all 3 angles
you are given two angles
can you calculate the 3rd angle?
oak chasm
like how do I even know that it is right angled
@tribal geyser The right angle symbols at point C.
oak chasm
For that, sum of angles is 180 degrees.
tribal geyser
yes yes thanks

When you multiply numbers of the same base you add their exponents. x^n * x^(n+1) becomes x^(n+(n+1))

Research factorial notation and show how factorials can be used in your solution.
How many 5 digit numbers can be formed from the digits 2, 3, 4, 5, 6 (without repetition)?

Evaluate the sum of the expression you got in e
It will depend on n but not on k since the k will disappear when you take the sum.

Can we replace 0 with C in the context of Exact differential equations because 0 is also a constant ?
such as C-C=0 so can we write C instead of 0

Can we replace 0 with C in the context of Exact differential equations because 0...
But why would you want to do that?
nimble matrix
because i am practicing exact diff equations and if we equate general solution to C and there is also a C present on left side and if we subtract them then we get 0 so 0 is a constant so according to my intuition, i think we can replace it with C but i need justification @glossy nymph

Nooo
You cannot cancel the constants since you don't know what they are
nimble matrix
Cant we do C-C
BTW i am getting a true answer
glossy nymph
And the point of having no constant in an exact integral is cause when you calculate upper and lower bound you subtract the same constant from itself. That's why you get no constant
In a general integral, you simply do NOT know what the constant is, so you have to call it c
nimble matrix
thats why i am writing C instead of 0
because then we can put limits in definite integrals
C-C=C and now we still have our constant C in equation
glossy nymph
C-C=C and now we still have our constant C in equation
No
In your general integral c is anything. In definite, c is 0
They are not the same
oak chasm
C-C=C and now we still have our constant C in equation
C - C = 0.

How is 5-0=0?

You better provide the context you wanna use it for.

When you put the C in eqn iii.) How were your sure that it's the same C on both sides?
I mean we write C to show any arbitrary constant but it doesn't mean it's the same value, you get it?
nimble matrix
So if we put C in equ 3 and also equate it to C
Then there will be 2 C's left and right side so how else would we solve it ?

You can subtract both the Cs to form a new constant, say K. Or whatever you wanna name it
But you can't equate to 0 unless you have information that the constants are equal
nimble matrix
Why not name It C
glossy nymph
Why not name It C
Yes you can name it that too😅

That's what I was saying that after subtracting C-C, can we write just C rather than 0

night geyser
oh you didnt translate it enough
idk what the x axis of your original graph actually was
i assumed it was years
but apparently that was incorrect

just increase 2000 until you get the correct placement i guess
without further information i cant be more specific

Please tell me im not going insane.
The question I have is
A) This triangle has angles in the ratio 1:2:3 please prove it is a right-angled triangle. Pretty easy right?
So I type: that there are 180 degrees
split into 6
so its 30:60:90
90 is a right angle
but i onlt get 1/2 marks?

Now, what would be the cost of talking if you were using kaseem mobile?
@keen fable
keen fable
27+0.12t

Now, the questions tells you that the 2 costs are equal
keen fable
yeah
upper sparrow
So, you put them equal. And solve for t
keen fable
oh ok
upper sparrow
but our teacher wants it to be 2 equation 2 unknown
Weird.
But ok, you can do that
So, just define one more variable
keen fable
which would be
upper sparrow
The cost of talking. Let it be c1 and c2.
So, u have c1 = cost for kareem
C2 = cost for hafeez
And c1 = c2 is your 3rd equation
It's basically, just beating around the bush though
