[crystal berry]

if you can do that

[novel remnant]

Why -

[crystal berry]

you can do this

[novel remnant]

Lemme try

[crystal berry]

diff cos you get -sin

-sin x sin = - sin sin

[novel remnant]

Hold on🤣

It takes time

[silver tundra]

guys help

[crystal berry]

wait till bro tries to differentiate

$\arctan(\ln(\sqrt(x^{2}e^{x})))$

[ocean seal]

[crystal berry]

smh bad tex

[novel remnant]

🤯🔫

[novel remnant]

Do computer science major get to this shit

What calculus is this

[crystal berry]

oh

no

ur good

[novel remnant]

Phew

[crystal berry]

CS is all about algorithms

and Linear Algebrs

[novel remnant]

We have cal1 and cal2 tho

And that’s only the first 3 semesters

[crystal berry]

diff eqs

type calculus

[novel remnant]

Ohew

Phew

Are you math major

[crystal berry]

yeah

well not pure

im doing

mathematics with computer science for statistical modelling

[novel remnant]

Holy

Do you have any free time🥲

[crystal berry]

uh

maybe

[novel remnant]

I don’t and I only have calculus🫠

[crystal berry]

why are you focusing on calculus if you're a CS student

[novel remnant]

Can’t imagine how much you have to study dude🥲

I’m asking that everyday lol

[crystal berry]

you should be focusing on linear algebra

💀

[novel remnant]

Why tf am I doing this shit

College shoves so much shit

I have politics critical thinking math and c++ this semester

[silver tundra]

ik this is easy 8th grade math but pls help I’m too tired to do this 😭😭

[crystal berry]

CS maths is 90% linear algebra and 10% number theory

[novel remnant]

Last semester I had fucking public speaking English

So much bullshit

[novel remnant]

It’s not cs math tho it’s just like math

[crystal berry]

ong

[novel remnant]

Some people in my class aren’t cs majors

[silver tundra]

help me bro

[crystal berry]

firstly its the wrong channel

[silver tundra]

oh

[crystal berry]

find another help channel

[silver tundra]

shit

[crystal berry]

[crystal berry]

um

wrong command

[silver tundra]

I’m so confused

[novel remnant]

7x1000+2x100+5x0 is the next step

[crystal berry]

find math help available

[novel remnant]

Bro took over my channel😭

[crystal berry]

anyway brother you should learn linear algebra

[novel remnant]

Wait I’m confused is that an x or a multiplied sign lmao

[crystal berry]

vectors, matrices, eigen stuff

[novel remnant]

Say that to my college lol

I wish I could just study computer science

[crystal berry]

and then you get to do fun CS stuff like optimisation and linear programming

im talking

[novel remnant]

But they shove all this shit to make you pay more

[crystal berry]

SVD

[novel remnant]

I wish

[crystal berry]

gradient descnet

descent

[novel remnant]

But again these are mandatory classes

English101,201 3 electives 3 math classes

It’s all core

[crystal berry]

i mean u do need calc knowledge for gradient descent

hmm

[novel remnant]

Absolutely not

But again

Out of my control

I don’t do this I can’t graduate

It’s all about money

[crystal berry]

u can do it bruv

wait

how old r u

[novel remnant]

24

[crystal berry]

im not in the US

so idk

[novel remnant]

Oh

[crystal berry]

damn

[novel remnant]

Then it’s a US thing lmao

They shove shit to make you pay more

[crystal berry]

bro's 24 with a nezuko pfp

[novel remnant]

Cuz you pay for each credit

[novel remnant]

I’ll be 70 with a nezuko pfp🔥

[crystal berry]

nice

[novel remnant]

Hell I wear nezuko shirt too😭

[crystal berry]

anyway

back to your

uh

differentiation 🤣

[novel remnant]

Hahaha

Hold on

?

Correct?

[crystal berry]

try

[novel remnant]

Hell yeah

It is

FUCK I KNEW IT

🥲

We have the quotient rule now

What’s the rule again

[crystal berry]

bruh

quotient is just product

in disguise

[novel remnant]

No it’s different

I remember

[tight pier]

unfortunately i am 7th grade 😭

[crystal berry]

sin(x) / x^3 = sin(x) times 1/x^3 = sin(x) times x^-3

[novel remnant]

There’s something squared in the division

And the order matters too

[crystal berry]

nah dont use quotient rule

its gei

[crystal berry]

do this

[novel remnant]

Can you put it in the picture form please

It’s x cubed??

I’ll never remember that bro😭

[crystal berry]

$\frac{sin(x)}{x^{3}} = sin(x) \cdot x^{-3}$

[ocean seal]

ℵ₁

[novel remnant]

What the hell😭

[crystal berry]

wdym what the hell

thats highschool shit

[novel remnant]

Oh hold on

What’s the rule

Just that you do -exponential??

[crystal berry]

$x^{-n} = \frac{1}{x^{n}}$

[ocean seal]

ℵ₁

[novel remnant]

And that’s how you find the derivative?

(-3)(-1)x**-4?

No hold on

Anyway it’s -3x^-4?

[crystal berry]

just apply product rule

[crystal berry]

yessir

[novel remnant]

Oh and then I do the product rule after that

that makes sense now

[crystal berry]

you can derive quotient rule

actually

[novel remnant]

Didn’t you say it’s gay

Lol

[crystal berry]

if you do f(x) times g(x)^-1

product rule

[crystal berry]

it is

math ≠ memorising formulas

math = deriving formulas

[novel remnant]

I know it’s understanding the logic behind it

But I gave up on that when I started calculus

Now I just suffer

[crystal berry]

just like how I derived the zero inflated poisson distribution from a coin flip this morning

[novel remnant]

Our professor is allowing us everything on the exam too🤣

Calcs, notes, books, fucking phones💀

[crystal berry]

bernoulli -> binomial -> poisson -> ZIP

im a chad

[novel remnant]

And it’s all multiple choice questions💀

[novel remnant]

Nani

[crystal berry]

thats wild

we cant bring shit to exams

[novel remnant]

Zip files?

[novel remnant]

Not even a formula page?

[crystal berry]

zip is zero inflated poisson

[crystal berry]

nah they expect us to derive the formulas 😭😭🙏🙏

[novel remnant]

The first one sounds like Italian food

[crystal berry]

fr

[novel remnant]

Bernoulli🤌🏻

[crystal berry]

and poisson is fish

in french

[novel remnant]

Lmaoo

Foods to zip files

Wth has math become

I just wanna study c++ and develop video games bruh😭

[crystal berry]

void main(){
  printf("Im Gay");
}

[novel remnant]

🤣🤣

What language is that

[crystal berry]

😑

[novel remnant]

Printf isn’t c++

Is it c

[crystal berry]

c++ is superset of c

sure you use std::cout

[novel remnant]

In c++ it’s cout << or std::cout <<

Yup

[crystal berry]

bur you can still use printf

[novel remnant]

Oh you can use the c functions?

I thought it’s only build on top of it but with everything changed

[crystal berry]

😑

[novel remnant]

Alright bud

I’ve been studying it for like three weeks🤣

We didn’t even do while loops

[crystal berry]

oh

I've beeb studying it for 2 years now

been*

[novel remnant]

I’m only on my second semesters

[crystal berry]

noice

c++ is fun

[novel remnant]

Took a whole break after high school lol

[crystal berry]

unlike python

[novel remnant]

It looks like it fs

[crystal berry]

but I love python too

[novel remnant]

Yup I had python last semester

It wasn’t as fun

[crystal berry]

the snake I mean

[novel remnant]

I find c++ easier too

[crystal berry]

🤣

[novel remnant]

Lmaoooo

[crystal berry]

ur tripping

wait till you see pointers

[novel remnant]

I saw it😭😭 I don’t get the point

Why would I ever use pointers

[crystal berry]

memory allocation

malloc

calloc

[novel remnant]

But the syntax of c++ makes more sense to me

[crystal berry]

fair

[novel remnant]

I love the brackets too {

Looks nice

[crystal berry]

learn java

c++ without the hassle

[novel remnant]

That was the first language I touched back in high school

Java has a lot more syntax tho

[crystal berry]

sicj

sick

[novel remnant]

System print out

Cout

[crystal berry]

but they make sense

unlike c++

anyway

r u done w ur questions nezuko chan

[novel remnant]

🤣🤣

Not close even

[crystal berry]

brev

[novel remnant]

We gonna be here all night Alef

Buckle up

[crystal berry]

do you even know what aleph 1 is lol

[novel remnant]

Yes Hebrew is my first language lol

[crystal berry]

its the "cardinality of the continuum"

oh

[novel remnant]

Wth is that

[crystal berry]

i mean in maths

LOL

[novel remnant]

😭😭😭

WHAT

It’s used in math??

Since when

[crystal berry]

yesh

idk

aleph null is the cardinality of the countable sets

aleph one is cardinality of continuum

meaning imagine you have infinite sets of infinity

[novel remnant]

Aleph for me is just the first letter of the alphabet lmao

[crystal berry]

that's how much rizz I have 🤫

[novel remnant]

Lmaoo

[crystal berry]

[novel remnant]

Does that also mean you can only infinitely approach a woman but never make contact

My first calculus burn🥲

[crystal berry]

fr 😭🙏

thats the point

[novel remnant]

Hell yeah😭 I was hoping I got that right

[crystal berry]

[novel remnant]

Alright lemme do this calculation hold on🤣

[crystal berry]

[novel remnant]

Hell yeah

Only 7 questions left for the homework and 107 for the exam review🥳🥳

Wth is this guy doing here

What’s the derivative of secent

[tacit arch]

Use sec = 1/cos

[crystal berry]

NO WAY ITS RIEMAN THE MATH WIZARD

all hail the math wizard 🛐

[novel remnant]

Lmaoo

[novel remnant]

Oh the rule from last semester

Damn I miss that time

So basically it’ll be 1/-sin?

[tacit arch]

No

Use quotient rule or power rule and chain rule

,tex .diff rules

[ocean seal]

riemann

[novel remnant]

What🥲

[tacit arch]

The right side is a fraction

[novel remnant]

Oh no

So it’s a quotient rule of a quotient rule,

??

[crystal berry]

huh

why

[novel remnant]

Cuz that’s only part of the answer

[crystal berry]

express 1/2/4 in terms of x/y

[novel remnant]

I gotta do quotient rule for 1/cos

Then the answer of that/6x

[novel remnant]

What is 2 and 4

Where did that come from

[crystal berry]

just an example

[novel remnant]

So 1/cos/6x?

Complex fraction quotient rule??

How th do I do that

[crystal berry]

$\frac{\frac{1}{cos(x)}}{6x}$

[ocean seal]

ℵ₁

[crystal berry]

glgl

[novel remnant]

Wym gl😭

Idk how to begin

[crystal berry]

if we have

1/2/4, its the same as 1/2 x 1/4 yes?

[novel remnant]

Is it?

I have no idea

1
2
4

How is it the same

I have no idea how to look at it

Y’all lied to me

It’s just this

[crystal berry]

bruh

u cheated

u need to put in effort

[novel remnant]

Effort in what I have no idea how to approach it

It’s like telling a week old baby what’s 2+2

I have no context to this

[tight pier]

a baby has two fingers

[novel remnant]

He has no idea what to do with them

And you need 4 fingers anyway

[tight pier]

so even with context you would have no idea??

[novel remnant]

I wouldn’t know

[tight pier]

what is even the question

[novel remnant]

Until I tried

[tight pier]

the other guy is getting cooked by his queen

[novel remnant]

They wanted me to calculate this

And I have no idea where to even begin

[novel remnant]

Wut🤣

[crystal berry]

bro what

my queen is studying quantum information theory

I'm actually getting cooked

[marsh ravine]

Guys can i ask

[crystal berry]

ask what

[marsh ravine]

About this question i have

[crystal berry]

find another channel

[marsh ravine]

Aight thx

[novel remnant]

Erm excuse me sir

[marsh ravine]

I'm new here dont mind me

[tight pier]

Someone else is already using this help channel. If you need help with a question, please open your own help channel/thread (see #❓how-to-get-help for instructions).

[novel remnant]

ANYWAY

Back to my question

Am I on the right track

[tight pier]

,rccw

[novel remnant]

WITCH

[tight pier]

what is this

sec(x)/6x?

[novel remnant]

The start of the quotient rule

Yes

[tight pier]

Do you even know it?

[novel remnant]

Yes I took the derivative of the top and the bottom

Now I put it

Together

Hold on

Thank you

[ocean seal]

bacc

[novel remnant]

I was looking at this and it broke my brain

[tight pier]

ye

[tight pier]

and this fixed it again?

[novel remnant]

WHY NOT😫😫😫😫😫😫

[crystal berry]

that handwriting is crazy

[novel remnant]

Shush🤣

Typing is my shit

[novel remnant]

Yes

Wtf did I do wrong

[tight pier]

why twice 6x

where did you learn algebra bruh

[novel remnant]

Cuz it’s being distributed

[tight pier]

you in calc 1

[novel remnant]

???

[tight pier]

no

it's not a(b+c)

it's

abc

all factors

[novel remnant]

What

[tight pier]

yes

[novel remnant]

It’s (ab)(c)

[tight pier]

which is abc

[crystal berry]

bro

[novel remnant]

Wtf

[crystal berry]

ur actually cooked

🫥

[tight pier]

insanity how you came through till here actually

[novel remnant]

So (xy)(6) is 6xy???

[tight pier]

yes

[crystal berry]

💀

[novel remnant]

WHAT

😭😭

[crystal berry]

bro is fighting the ice dragon even tho bro lost to a mere goblin

[tight pier]

bro nezuko

[novel remnant]

It all went downhill when the fucking sin cos and all these came along😭

I hate that shit

[crystal berry]

no comment

[livid sage]

what do u study bro

[novel remnant]

Lmaoo

[crystal berry]

mathematics and computer science for statistical modelling

[novel remnant]

This makes no sense to me

[crystal berry]

how does it make no sense

[novel remnant]

Each one should get one

[tight pier]

witchcrafting a summand

[novel remnant]

Because it’s being multiplied

[tight pier]

ok

[crystal berry]

then try multiplying 3(2*5)

[tight pier]

what is

[novel remnant]

But that’s the same

These are all numbers

But x and 6 are differents

[crystal berry]

huh

x is any number

[tight pier]

x is also a number

[crystal berry]

what u on

💀

[tight pier]

dont be racist against x

[novel remnant]

😭😭

[tight pier]

x is as real as 1

[novel remnant]

But why is it called then multi something

Multivariable or smth like that

[tight pier]

2 * x = x + x

[crystal berry]

bro is still struggling on Algebra 1 and doing Calculus

[novel remnant]

😭

[tight pier]

it's insane

cause he actually dont struggle with calc

he gets the derivatives

it's the arithmetics

[novel remnant]

Look I didn’t study math the right way okay😭 my road was paved with blood

[tight pier]

ok nezuko

[novel remnant]

I’m just baby🥲

[crystal berry]

bro ur 24

[novel remnant]

I just wanna study code man😫

[crystal berry]

then take a bootcamp

dont go to college

[novel remnant]

I can’t I’ll get deported😫

I’m on a visa

[crystal berry]

bruh

[novel remnant]

🥲

[tight pier]

you should just listen to us rn and question it after you are done

otherwise it's a waste of time

[novel remnant]

I believe you

I just don’t get it lol

But lemme try

[tight pier]

watch a video after

[crystal berry]

[tight pier]

yea i am saying just accept that you dont get it

[novel remnant]

That’s true

[tight pier]

so you were having a 6x too mich

[novel remnant]

Like everything in calculus lol

It’s like when the limit is x—>5 and then you have y=x^2 and you put 5^2
I don’t get that shit

How can you replace x with 5

[novel remnant]

If x only approached 5

And is never actually 5

That makes no sense

[crystal berry]

yoi dont

you dont

[novel remnant]

You do

We did that

On the first week of calculus

[tight pier]

bro just changed topic

[crystal berry]

you dont "replace"

[novel remnant]

We yapping we having fun

[novel remnant]

You know what I meant

[tight pier]

aight bet

[crystal berry]

if you replace then the derivative of anything would be 0

since the definition is divided by h as h -> 0

[novel remnant]

No I mean before derivatives

Forget derivatives

Just limits

Y=x^2 while limit x—>5

[crystal berry]

i think a good think about limits is that, when the equation is simple, then "replacing" would be so accurate

but if the equation is complex

then simply replacing it would not be accurate

[novel remnant]

So it’s only when it’s something simple?

[crystal berry]

yeah like x^2

its simple

[novel remnant]

But it still doesn’t make sense how x can be 5

Because it can never be 5

[crystal berry]

its not 5

it approaches 5

[novel remnant]

So how would you solve it

[crystal berry]

we approximate that its 5

since it approaches 5

[novel remnant]

By making it 5

[crystal berry]

i.e we dont have any other information

so making it 5 would be the best estimate we have

[novel remnant]

So we never have a definitive answer then

Damn

[crystal berry]

that's calculus

:))

[novel remnant]

That’s gonna be fun for my ocd lol

[crystal berry]

or to be more accurate

"Real Analysis"

its called analysis because you're analysing / estimating stuff

[novel remnant]

I only got the concept of analyzing it when we used it for speed

Like to find the speed velocity and acceleration

[crystal berry]

the derivative is also an estimate lol

integral too

[novel remnant]

Ffs😭

[crystal berry]

anyway

[novel remnant]

Let’s goooo

This one only took an hour this time

[crystal berry]

nice

[novel remnant]

The exam is gonna go amazing it seems

We have an hour and 40 mins😭

[crystal berry]

ur cooked

so

ill explain why

6(xy) is 6xy

[novel remnant]

We don’t gotta show any work luckily so I’ll just ask ChatGPT😭

[crystal berry]

say we set z = xy

[novel remnant]

Listening

[crystal berry]

what does 6z mean

it means z + z + z + z + z + z

[novel remnant]

Mhm

[crystal berry]

so 6(xy) is

xy + xy + xy + xy + xy + xy

and what would that be?

[novel remnant]

Wth

I thought it’d be x+x+x+y+y+y😭

[crystal berry]

huh

[novel remnant]

Like half and half

[crystal berry]

thats 3x + 3y

[novel remnant]

3*2

[crystal berry]

why would it be that

💀

[novel remnant]

No wait

Wait continue

[novel remnant]

From here

[crystal berry]

no i finished

thats it

[novel remnant]

And assign numbers please

To make it equal

[crystal berry]

wdym

[novel remnant]

What would z= x= and y= to

[crystal berry]

anything

[novel remnant]

Huh

All 3 of them??

[crystal berry]

z = xy

x could be anything

y could be anything

[novel remnant]

Yes but like make it make sense with numbers

Cuz it can’t just be anything

[crystal berry]

okay

6(3 * 1)

is 6 * 3 * 1

[novel remnant]

Z is 6?

[crystal berry]

which is 18

[novel remnant]

Bruh that makes no sense

[crystal berry]

how does it make no sense

6 * 3 is 18

[novel remnant]

6=3*1

That’s wrong

[crystal berry]

6 is not z

z is 3

[novel remnant]

Put it in the same format please I’m trying to click it in my brain🥲

Z=xy

3=what two numbers

[crystal berry]

okay reset

the rule is:

a(bc) = abc

proof:

let z = bc, az = z + z + z ... a times. Since z = bc we have that az = bc + bc + bc ... a times.

example: let a = 2, b = 3, c = 5

2(35) = 23*5

im actually sleepy

[novel remnant]

So a is the amount of repetitions

I see

And as many repetitions as z have

Bc must have too

So 2 z is 2bc

z+z=bc+bc

z=4, b=2, c=2

4+4=22+22

8=8

I see

So z will always have double the value of bc too?

Like of bc separate

[lone heart]

@novel remnant Has your question been resolved?

[sinful rock]

Yo

[novel remnant]

Hey

[sinful rock]

I will help you

you'll need to use the product rule for derivatives. The product rule says that if you have two functions,
f
(
x
)
f(x) and
g
(
x
)
g(x), the derivative of their product is:

(
f
(
x
)
g
(
x
)
)
′

f
′
(
x
)
g
(
x
)
+
f
(
x
)
g
′
(
x
)
(f(x)g(x))
′
=f
′
(x)g(x)+f(x)g
′
(x)

The blue graph is
f(x).
The red graph is

g(x)

Move the point
A
A along the x-axis and look at the tangent lines at each point.

The slope of the tangent line gives the derivative of the function at that point (so
f
′
(
x
)
f
′
(x) or
g
′
(
x
)
g
′
(x)).

Basically, just use the applet to get the slopes and values at each point, then use the product rule to calculate the derivatives.

[novel remnant]

Bro wait wait I can’t see anything

[novel remnant]

??

i dont get which numbers are which on the graph

it says the slope is 0 for one but for the other its(1,1.5)

and then the derivative of g which line is it

im so confused

[balmy grail]

Derivative of g has the black line with slope 1 in the top left. The derivative of f looks to be the same as the x axis

[novel remnant]

so 1 and 0

[balmy grail]

Yes

[novel remnant]

What about here?

The red g is 2

And that’s the slope

Or the derivative

And then the blue one is 0

But how is that 0 if it’s not aligned with the x axis

[balmy grail]

Slope of g overlaps x axis. Slope of f is -1

[balmy grail]

No

[novel remnant]

Where do you see that🥲

I don’t see -1 anywhere

The black line is the derivative right?

Of the function itself

[balmy grail]

Sorry, -1.57 in the brown

[novel remnant]

How do you know it’s that?

I don’t get what belongs to what

[balmy grail]

It’s the tangent line at that point

[novel remnant]

How is that even a tangent line if it touches the graph at multiple points at once

[balmy grail]

Try moving to x=3

[balmy grail]

It only touches the blue curve once

[novel remnant]

It looks like it touches it all along this line

Like they are overlapping

[balmy grail]

In that area, it looks like it, but it’s probably just a display error and they’re very close but not the same

[novel remnant]

Ohh I see

So basically using the product rule I do 2*-1.57+0*0?

Fuck

[balmy grail]

Though if you look at x=2.5 the tangent line will cross the curve more than once. The key is a tangent line has the same slope at the point it lies tangent to, not that it only touches the curve once

[novel remnant]

2 times 1.57 + 0 times 0

[novel remnant]

Ohh I see so it sometimes works with multiple points as long as they have the same slope

Thank you that makes sense

[balmy grail]

Yep

[balmy grail]

This us what I mean

Because the derivative is not constant, and the concavity changes sign long enough that the tangent line hits the curve again. The tangent line only shows the slope near the point of tangency

[novel remnant]

It’s wrong🥲

Sorry too blurry hold on

[balmy grail]

Negative 1.57

[novel remnant]

Oh I assume it’s something we didn’t learn yet😅

Right! Whoops

[balmy grail]

It’s something that will probably come back later, but if your homework is on tangent lines you should know it

[novel remnant]

The professor only mentioned not touching two points on the graph lol

That’s why that’s what I knew🥲🥲

[balmy grail]

The definition is that the slope is the derivative at that point, and it crosses that one point. Not that it only touches the entire curve at one point

Though, it’s better than a secant line, which approximates a tangent line by crossing the curve at two points

[novel remnant]

Yes that’s what we learned, how it approaches eventually becoming the tangent line

Thank you for your help and explanations😄

[trim pelican]

[slim barn]

!!!

[slim barn]

my first part of point slope is correct

the other two are not

[tacit arch]

How did you get 1/9

[slim barn]

(-18,0) (0, 2) points

2/18

1/9

[dawn cosmos]

how is it

-18?

u mean -1/8

and so gradient isnt 2/18

its 2 / 0 - (-1/8)

so 2 / (1/8)

so 16

[slim barn]

y-2 = 16(x-0)?

[dawn cosmos]

ive never used point-slope

but slope-intercept

is y = 16x + smth

[slim barn]

y=16x+2?

or probs -2 now that i look at it

no wait im slow

[dawn cosmos]

yes

[slim barn]

+2

[dawn cosmos]

huh

yeah +2

[lofty pollen]

huh-

[slim barn]

so that means yeah point slope is 16(x-0)

okay okay

[dawn cosmos]

what

[slim barn]

thank you, i got mixed up on reading fractions

[dawn cosmos]

nah wait i think i did it wrong

[lofty pollen]

i think so too 😭

[slim barn]

it says it was correct

[lofty pollen]

@slim barn question?

[slim barn]

the system

yea wassup

[dawn cosmos]

wait

what no i didnt

its right

[slim barn]

yea ur cracked dw

[dawn cosmos]

@lofty pollen never doubt me again bruh

[slim barn]

🧠 💥

brain blast

[lofty pollen]

wait wait

[dawn cosmos]

REALLLL

[lofty pollen]

waiiit

oh yeah

its right

what method you used? @dawn cosmos

[slim barn]

call him himmy neutron up in dih bih

[lofty pollen]

frf

[dawn cosmos]

m = y2-y1 / x2-x1

[dawn cosmos]

yes flipping sir

uk im like that

[lofty pollen]

OH sht

mb

k

its goat

nice

[dawn cosmos]

appreciate it

!!

[lofty pollen]

im getting so rusty at math

[dawn cosmos]

☠️

[lofty pollen]

i needa exam now

[slim barn]

okay so you need help with this question

?

[lofty pollen]

yaur!

[slim barn]

well, to solve

[dawn cosmos]

so basically if u divide math by rusty

[slim barn]

you must solve math equations

and then find maths coefficient

[dawn cosmos]

(math) / (rusty)

[lofty pollen]

i mean rusty can be y here

[dawn cosmos]

ohh yeah

and let math = x

[slim barn]

and divide mols/g to get the molar mass of N2

[lofty pollen]

and math can be x

yeah!

[dawn cosmos]

x / y

[lofty pollen]

:0

[dawn cosmos]

and then uh find the inverse tan

[slim barn]

and then utiilize the function of the balanced chemical equation

[dawn cosmos]

u get angle of 30 degrees to antartica

[lofty pollen]

and i did the x/y guys

its telling me to

kill myself

😭 🙏

[dawn cosmos]

HSSHDLSADHDLAHSD

[slim barn]

you forgot y^2 + 3

[lofty pollen]

:0

[slim barn]

i think that's where you went wrong

[lofty pollen]

yeah

ig

wait lemme see 🤔

[slim barn]

anyways, say thank you.

and close the channel

[lofty pollen]

wow

what a genius

i owe you 😂

[stark crater]

What have u tried

[iron dragon]

I'm confused it says p is true q is true and whenever p is false and r is true, why does it matter if r is true, if p is false the whole thing is true right?

[stark crater]

Nah they are defining this tertiary operator to have the given properties. I think you may be letting your knowledge of normal (if p then q)s influence how you read this, but that isn’t relevant here

[iron dragon]

why isn't the knowledge of normal (if p then q) needed anymore?

[stark crater]

Yeah sorry that might have been misleading

You know that in the statement “if p then q”, if p is false then whole statement is true. This property does not hold for the statement “if p then q else r”

If p is false then you also need r to be true for “if p then q else r” to be true

[iron dragon]

yea I don't understand why that is

[alpine sable]

its giving you hint that statement is true=p is true and q is true also when p is false and r is true

[iron dragon]

why would r matter though? if p is false everything is true

when an implication's premise is false, it's true

[alpine sable]

try to take example of certain statement and let them be p,q,r then solve it

[stark crater]

It is given in the problem.

“If p then q else r” is true only when these conditions are true

1. If p is true then q is true
2. If p is false then r is true

For example if p=T, q=T, r=F, then by 1. if p then q else r is true

Another example, if p=F, q=F, r=T is true then if p then q else r is true by 2.

Now if p=F, q=T, r=F, then if p then q else r is false because it does not satisfy 2.

[alpine sable]

you will get the answers then

[iron dragon]

so it wants me to write a truth table with the rules it gave me?

[stark crater]

Yeah

[iron dragon]

do you know what the sign is for else?

i've never seen else yet in the textbook

that's what's strange about this

p q r p--->q else r
0 0 0 0
1 0 0 0
1 1 0 1
1 1 1 1
1 0 1 1
0 0 1 1
0 1 1 1
0 1 0 0

[stark crater]

First 6 rows are good

[stark crater]

Not exactly sure what you mean by this

[stark crater]

Yeah they are defining it for the sake of the problem. You probably wont use it much later

[stark crater]

Last 2 rows (after edit) are an issue

Remember the 2nd condition “if p is false then r is true”

If p=F then (p is false)=T. We have r=F. So (if p is false then r)=(if T then F)=F

[iron dragon]

i'm lost

[stark crater]

Are you able to point out a specific part you get lost at

[iron dragon]

the statement is true when p and q is true

and whenever p is false and r is true

2nd to last row, p is false, r is true, so true

and last row is p is false and r is false so false

[stark crater]

Yes 2nd to last row is good I think edit may have confused me

Let me recheck everything

[wintry wadi]

5th line is wrong

the statement is saying
if p is true, then take q
otherwise, take r

[lethal pollen]

hi there nay i have some help w the following

[stark crater]

!occupied

[lone heart]

Someone else is already using this help channel. If you need help with a question, please open your own help channel/thread (see #❓how-to-get-help for instructions).

[iron dragon]

let me rewrite the table

p q r p --->q else r
0 0 0 0
0 0 1 1
0 1 0 0
0 1 1 1
1 0 0 0
1 1 1 1
1 1 0 1
1 0 1 0

[wintry wadi]

group the p=1 and p=0, it's easier to see that way

last line is wrong btw

correct now

[iron dragon]

for b it wants me to write a statement that is logically equivalent using signs

but I've never seen else in the textbook

[stark crater]

Dont worry about not seeing else before. Think about how if p then q is equivalent to not p or q. You should do a similar thing here.

[iron dragon]

if p then q = (-p V q)

[stark crater]

Yeah

If I gave you a truth table for if p then q without ever telling you what “if” and “then” mean, you could have figured that out.

Now you are given a truth table (you found it) for if p then q else r, and you can find a logically equivalent statement without ever knowing what if, then, or else even mean

[iron dragon]

the statement I make needs to have all the same truth values

I don't know how to do that because the rules they gave us doesn't follow the normal logic rules

ohh

(p /\ 1) /\ (q /\ 1) /\ ((p /\ q ) / (-p V r))

[stark crater]

Lol how did you get that. No idea if it works but there is a much more concise way using only 2 connectives

[iron dragon]

if I am this bad at math should I give up on trying to get through my degree

I have dropped math classes for years because in the first 2 weeks they are always too hard

[stark crater]

If you have the money and you enjoy the subject you shouldn’t quit

[iron dragon]

well I enjoy Computer Science, but I can't do the math

and they won't let me further in Computer Science without the math now

[alpine sable]

good evening everyone

[iron dragon]

good evening

[alpine sable]

im guessing your school requires a certain math level for cs?

[iron dragon]

yes

[alpine sable]

are you able to do math credit over the summer

[iron dragon]

Calculus 1, Calculus 2, Calculus 3, Discreet Math, Linear Algebra and Stats

[alpine sable]

at another highschool

ah

[iron dragon]

and i've only done Calculus 1 and I keep dropping Calculus 2 and Discreet math, and I'm thinking I might need to redo Calculus 1 again

[alpine sable]

well is there anything you dont get?

[iron dragon]

but Discreet Math doesn't even need pre reqs and I'm struggling in it too

If I'm not good at something I get discouraged

and I'm not good at math so it's really hard

[alpine sable]

take your time

dont rush anything

you need to find the right balance of study

[stark crater]

Might look into related majors. In the US many colleges have software enginner majors, information technology, etc that require less math than cs.

[alpine sable]

and taking time to understand

[iron dragon]

software engineering at my school has the same amount of math + physics + chemistry

[stark crater]

rip

[iron dragon]

maybe I should look to do school in a different country

[alpine sable]

hmm can you reserve yourself some time to study

every single day

just an hour or so

[iron dragon]

yes

[alpine sable]

try that

just review a bit

everyday

[iron dragon]

but I take like 10 hours on 1 question

[alpine sable]

no distractions

[alpine sable]

you just gotta practice

yknow the different forms of friction?

static friction is stronger than kinetic

its gonna take more force in the beginning but once you cross the threshold

things are easier

[iron dragon]

think I should learn on my own outside of the class before trying to take the class

because I keep dropping the classes because they move so fast

[alpine sable]

yeah

try to preview lessons

so you have time to process

before the teacher throws shit at you

[iron dragon]

I dropped all classes and I'm trying to decide if I should add some back or take the semester off

and just study math on my own and then come back next semester already knowing it

if possible

@stark crater you said there's a way with 2 connectives?

[stark crater]

Yeah you can do it with an “and” and an “or”

[iron dragon]

(p AND q) OR r

[stark crater]

The strategy is to look at patterns in p q, then patterns in q r, then patterns in p r

[stark crater]

Yes exactly

[iron dragon]

wait though

how do you know that's right?

[stark crater]

Compare the truth tables

[iron dragon]

using the normal rules or the rules they made up?

[stark crater]

You compare the truth table you found in part a with the truth table of (p and q) or r.

To show two statements are logically equivalent you show they have equivalent truth tables.

In the question they didn’t really “make up rules”. They defined a logical operator. This is not really any different than defining a function like f(x)=x^2. Instead of function though they defined a logical operator (which is kind of like a function)

[iron dragon]

ok they do have the same truth tables

now they want me to write something logically equivalent to p ---> q else r only using p q r ~ -->

[stark crater]

Do this idea

[iron dragon]

patterns on the truth table?

[stark crater]

Yeah. For example when p,q are true, does r being t/f influence the truth value of the entire statement? Or when p is true and r is false, does the truth value of q influence the total truth value?

Think about properties of p -> q like how when p is false then the entire statement is true.

Another strategy is to just completely make up a guess and see where it fails. This may help you gain some inspiration on how to improve your guess until the truth tables completely match

For example you may start with p -> q -> r and see where this fails

[iron dragon]

how did you get so good at discreet math?

( p --> q ) --> r

[stark crater]

After writing a lot of proofs (im in my 4th year of math major) you understand this more.

Also it can hard when you first start but luckily logic is something you can apply to tons of stuff outside of math so eventually you gain intuition for it

[iron dragon]

are some people just not built for math? I feel like that could be the case

[stark crater]

I don’t think that is true for most people. Sometimes people have rough foundations and fixing that can be harder than just learning from scratch.

I believe though if you use the right resources, have good teachers, and do things smart, almost anyone can get good at an undergraduate level of math.

[iron dragon]

I do have rough foundations, that's why I need to probably need to re do Calculus 1 but what foundations are needed for Discreet Math, it's a whole new Math starting fresh

[buoyant saddle]

if you’re struggling with calculus then you are just struggling with algebra

almost everyone i see in help channels who struggles simply lacks algebra foundations

discrete math is different for sure

logic is something entirely different than calculus

having mathematical maturity and just a brain tuned for logic which can be developed is really all you need

it doesn’t rely on the content from previous courses

[iron dragon]

how do I develop it though, when I am in university class it moves so fast I have to drop it in the first 2 weeks

[buoyant saddle]

practice

that’s all there is to it really

[iron dragon]

just read the book and watch youtube videos for the next 3 months and show up next semester?

[buoyant saddle]

some pick it up faster than others

[buoyant saddle]

i mean how many classes are you taking

you shouldn’t be that crunched for time

[iron dragon]

0 right now

[buoyant saddle]

0?

[iron dragon]

I was signed up for 4, 2 math classes and 2 electives

but trying to do Calculus 2 and Discreet Math took so much time

and I ended up having to drop all of them

[buoyant saddle]

isn’t the add/drop over by now

[iron dragon]

yea

[buoyant saddle]

at my school it’s been over for 2 weeks

[iron dragon]

but you can ask to add back after the deadline with a form

I've still been trying to do the work

[buoyant saddle]

bro you’re in no classes

why did you drop all of them

even the electives

[iron dragon]

because the electives will take time away from me actually learning the math

[buoyant saddle]

that was an impulsive decision

[iron dragon]

which is needed for the degree unless I change the degree

[buoyant saddle]

have you failed the classes already?

[iron dragon]

well I don't know what to do

I'm on question 1 of the assignment

and its due tomorrow

[buoyant saddle]

in the past

[iron dragon]

and theres like 5 questions

[buoyant saddle]

did you fail

[iron dragon]

and the Calculus 2 I had to drop because they moved into trigonometric integrals and integration by parts

and I'm way behind

I've never failed, I always drop before failing

but I've dropped Calculus 2 and Discreet Math like 5 times

[buoyant saddle]

i don’t man i don’t agree with dropping so much

bruh

[iron dragon]

or more

[buoyant saddle]

what’s your major?

cs?

[iron dragon]

that's what I want it to be

[buoyant saddle]

what year are you

[iron dragon]

but I can't be in the department without passing Calculus 2

I got accepted into the University for Social Sciences

but yea I was aiming for Computer Science

I'm year 2

but I've been at university for 12 years

[buoyant saddle]

wait fr?

how does that work

[iron dragon]

but 7 of those years I wasn't even at the university

[buoyant saddle]

so you dropped out?

[iron dragon]

yea

[buoyant saddle]

and are going back

[iron dragon]

yea

[buoyant saddle]

did you do a year first
