I usually just say
"Take the derivative"
I can't say that word well and sometimes I say derive on accident xd
You dy/dx that function

dbirb/dpizza
tenemos una variable en comĆŗn
š
pupper(crime) = dCrime/dPizza
don't think too hard about that one
didnt' someone need math help
im gonna go eat dinner
y despues, ver el siguiente capĆtulo de una serie
ufffff
i don't have anyyyy
Ew math
Math is epic
Maths* š”
??? Math is fine
Veraniego I can help you with your math hw
Ok
Can u help me find a polynomial time algorithm for factoring a product of 2 large primes
Yes
That's the point lol
maths>math
Yeah ok
i love vectors
I used to work with them when i was coding little games
Oh cool
and it was pretty interesting to see algebra in action
Coding is sort of hard but easy once you understand
We were doing a past GCSE paper and there were a few hard questions
Itās meant to be yeah
and more complex things
There was one
Wait I have a picture
It was really difficult
I confused myself
Ignore the working out
i love those things
i didnt learn those things in school thats why its even more interesting to work out a solution
now that i think about it a bit more its not even that hard
i might have had something like this in school
Can you explain it?
what do you mean?
How you would do it?
Yeah
But what does he get if it sells a losing ticket
50p?
I thought that's the cost of a ticket
Yeah
Oh he's selling them
Yeah haha
Ok, so he makes 50 cents per ticket and pays out 12 or 1.50
Or
Let x Be the number of losing tickets
He makes 50p if itās a losing ticket
He sells 7+75+x total tickets
id calculate the loss due to the winning tickets
Just by saying x has made this question a million time easier
and the win due to all the sold winning tickets
and thats the solution
5,15,25,35,45
Yeah 0 isnāt counted?
Oh right I see
Ticket number 5 is a winning one
Profit = sell price - pay out price
163 = (7+75+x)*0.5 - (7*12 + 75*1.5) solve for x
Yeah
just calculate how much prizes he paid out and and calculate how much he got for selling the winning tickets
Yeah that's what the above equation does
Iām still confused at how thereās 75
There are 5 tickets ending in 5 starting from 0 up to 50
4
5, 15, 25,35, 45
My eyes have been opened
So by induction you have 75 tickets ending in 5 from 0 to 750
yep with you now
Not sure if induction is the right term there but regardless
xd
Yeah
You know he sold those 75 tickets ending in 5 and those 7 tickets ending in 00
So you know how much he had to pay out
Yep
What you don't know is how much he earned from the tickets, since you don't know many he sold
Hence we use x to denote the number of losing tickets
but you know that he sold all the winning tickets
We know he gets 0.5 for each ticket sold
ooo gcse
So he gets 0.5 for each winning ticket he sold (7 + 75), plus for each losing ticket he sold (which is x)
i wrote the answer down. lets see if you guys get to the same solution
But 7 = 12
Expenses = 7*12 + 75*1.5
Yeah
So, what about the 50p that is already paid for
Did you take that into account with the equation
0.5 is the 50 cents
Looool
we're in £ town brother
So why is it a multiplier
2 * 0.5 = 1
Yeah I get that
4 * 0.5 = 2
Because you are multiplying (0.5 £ per ticket) by (7+75+x) tickets
To get the amount he was given for those tickets
Oh yes
So that's how you calculate his income
So thatās the profit from the actual tickets
You get profit by subtracting your expenses from the income
no need to apologize
Is income overall?
For all the tickets he sold
Donāt you need to add the profit too?
No, profit comes last
Profit = income - expenses
You don't add profit to income. That doesn't make sense
You can write it as income = expenses + profit, but to me that just makes it confusing
So
0.5(7+75+x)
Wait sorry this is very abrupt
I have to go for an hour or so, can I get back to you with this then?
Okay thatās fine, Iāll try to ping you if you are, thanks very much for the help anyways
ok lol
||like this||
||Like this||
my guess: ||15||
Surround your text with |
my guess is correct? @ashen mist
Does it satisfy the original equation?
i didnt check your equation. i was off for 25 minutes
that was my answer from 30 minutes ago
Uhh
@gentle heath u win
spoiler tags included
i didnt even check if it even makes sense
Double win
and it absolutely doesnt
but yeah. that was my try haha
and then i had to bring my son to bed haha
i better work on my concentration
thats ezpz
my idea of getting to the solution is like veraniegos
like the steps i had taken but while calculating it myself on my phone without making notes i kinda lost the path
either way
it was fun
No worries lol all part of the adventure
Iām back @ashen mist
got it yet?
Lol no Iāve been diving
loads of time
They start then
not gcses?
Yep okay now to simplify and find x
the fun bit
With paper lmao
163 = 37.5+3.5+x/2 - (84 + 112.5)
163 = 41 + x/2 - 196.5
163 - x/2 = 41 - 196.5
-x/2 = 41 - 196.5 -163
-x = 2(41 - 196.5 - 163)
-x = -637
x = 637
I think I got itttttt
indeed
Our whole class was struggling with that
But using algebra
Itās one hell of a lot easier
u trying to tell me they were trying to do that without algebra
its a maths paper
u do algebra
Always turn it into an equation
Word problems can be tricky to get used to
But that type of thinking will help you everywhere
Np
Iām going to do the test do the paper now, if the questions are quite difficult, am I able to ask you both for some help?
Ill be busy tonight but possibly
ye hmu
No problems, I can try to ask Sam
Hit us up
Iāve got myself into a muddle @gentle heath
show
the gradient is the rate of change
the rate of change of speed is acceleration
if you draw a tangent line at 6 seconds
and find the gradient of it
that will be your estimate of acceleration
Is that it
yep
did you draw a triangle on it?
take two points on the line
find the difference of the two y co ordinates
and the difference in x
Yeah
yeah if you did that
Thatās what I got I mean
ur good
@latent pulsar
Average speed for the whole journey
speed = distance/time
Yeah
and distance is the area under the curve
you know how long the journey took
just find the area under the curve
How come the distance is underneath
find the area of the little squares and count them
But the first bit
Like
Dont worry Iām not actually this dumb we havenāt done this since like a year ago or smt
^^
for each trapezium not for the whole thing
that's another way
it's hard to explain but split the curve up by drawing vertical lines underneath it
underneath the curve
split it into strips
then join the top of the strips
turning them into trapeziums
No Iāve done it before I know what you mean
^^ get it done then brother
Iāll give it a go
Cheers
I donāt count the squares that arenāt complete do I?
you're using that method? ;-;
How else is there?
the trapeziums..
Trapeziums?
brb ms paint
Lmfao
lol that'll help
Iāve never seen that
this is why we have integration 
I think weāve only been taught squares
im getting a headache thinking about how much effort gcse maths is
with bloody graphs
It really is
beautiful
don't scare the boy let him get his gcses gone before the calculus starts
except the other half of the graph is of straight lines so you just work out the area of the triangles
im just saying š
Dime
I had my stats exam today lol
i learned about quota sampling literally an hour before the exam
on the right it is
That looks fun
oh that's easy

they even give you the formula
Okay no flex pls
yeah I'm easing him in
in the exam
zed you a level or?
what board had their stats & mechs on tuesday
Can I just skip back into the question rea quick
gwon
fuck i can't even remember my own exam board
I legit have to count the squares
Idek how to do it otherwise
nooo pls dont count the squares i will choke
but thats what you have to do
How do I do trapeziums

OR JUST MAKE THE WHOLE THING EASIER AND FUCKING INTEGRATE THAT SHIT
yes
it gives no function
What do I do with said trapeziums
approximate it
find the areas of them
then add em all together
easy peasy
you know the formula for the area of a trapezium right?
What up
U have to find the acceleration given the velocity graph?
Yes
Who's talking about integration?
@vale quarry
it would be

Why
but they don't cover any calc in gcse
because fuck whatever the fuck this gcse shit is
Acceleration curve is the derivative of velocity curve

Don't say gradient lol this is single variable and you'll just confuse ppl
i dont suppose you're planning to do maths at alevel are you?
? gradient is the term
Gradient = multi variable version of derivative
@ashen mist Thats confused me lol
gradient is the gradient not whatever the fuck you just said wtf why so many words
You mean slope?
Sam what grade did you get?
9

i got 8, 4 marks off a 9 ;-;
ooo
Wtf
lmao i didn't pay attention to much in maths but had my dad teach me all the shit i missed
cause he was a maths teacher at one point
is that cheating?
Sam are you like a god or smt
I'm doing further maths alevel now
No Zed
nerds
I want to take maths and physics and A level
but not as impossible as people say
If you want to approximate the tangent line at a point, you can use secant line approximation

further maths at gcse was literally just maths in a level

We donāt have that
This is taking wayyyyyyy too long to find the trapeziums areas
They didn't have fm gcse at my place
maths is so much more harder in another language
i told you.. integration..
and veraniego is speaking american maths
You don't need to find trapezoiede areas
so 3 languages
i actually traded IT for further maths
haha
Oh ffs what do I do
Brb shower
even though i was getting pretty high grades in IT
my IT teacher was devastated lmao
LolL
no
This is taking way too long for what it should
not playing LoL
Am I doing it wrong?
wont help
picture?
maths in a nutshell
oh you don't have to do a trapezium for every few squares..
larger trapeziums

make big ones not smol
i screenshotted this wise maths trick
it's not wrong it's just time consuming
you're gonna miss a few squares but theres usually a pt2 asking whether ur things an over or underestimate
There is lmao
yeah as long as it says 'estimate' then you're good
but don't do 20 fuckin trapeziums
do 18
^^
Are you just naturally good at maths?
make em big
Thatās what I was thinking
looking back at gcse maths now..
Its really not hard
A level is kinda the same
FM is fucking hard
Do yo guys find English hard?
a level fm?
To which one lol
6&7
i got an 8 in english language
7 in literature
and i absolutely fucking scraped two 7s in science
You guys are a bit smarter than me
only maths and english were number grades when I did them
He was first year
my year was the pilot year
all my subjects were numbers with fm being the only letter
now we've got letters again
in a level
what's hard about english?
I donāt know
english was effort
like analysing stuff or creative writing kinda stuff?
ye
Like I just donāt fully pick out the stuff I need
f english
Preach
fell asleep memorising quotes
yeah that was the worst part
so many great books ruined by having to study them
but then again, without them i wouldn't know of many famous books
well i mean i probably would but not as well
i disagree
blood brothers is arse too
i liked john steinbeck
i think the ones we did were animal farm, of mice and men, this one short story about a homeless dude i dont remember, and a load of shakespeare
oh good
Iāve got all the squares
find the area of all your shapes and add that shit up
Weāre doing Macbeth, Jekyll and Hyde, blood brothers and inspector calls I think
oh yeahhh jekyll and hyde
Sorry nex
i read that like
Jekyll and Hyde is good
7 years ago?
i never finished half of those books
What do I do with the final total
that's ur answer my dude
total area/time
This is wrong surely
bit fast
if distance isn't the question
45 wtfff

you've got dudes buying 50 watermelons dont worry about it
since when has gcse maths been realistic
Where hemos gone wrong
nah look at the graph it's way too big
No but like the fastest is 12 m/s xD
did u work out the areas of the trapeziums wrong or smth?
and dont forget to half the triangles
Yeah yeah
show
Ah thatās it
what, the triangles?
it's always the triangles
has anyone seen that one bit in black adder with the triangles?

Lol not yet
Wait
Have I been super stupid
Like proper retarded
Iām meant to use the scales on the graph
Am I right
yes..
Fuck
what have you been using..?
The amount of squares omfg
Dude
sam this is your fault
Sam
i tried to warn you
Tut tut
manipulating minors
No wonder this has taken so long
LOL
May aswell be
Sam is dead
como se ha muerto?
Anything is an insult a this point
I ate him
@gentle heath you fucking nonce
Lmaoooo
Does that offend you
if you're getting acceleration from velocity, you shouldn't be calculating areas of anything
we moved on from that
Thatās what I said!!!
Because GCSE bruh
no that's how physics works
idc what GCSE says
anyway I got lost cuz I was showering
we were finding the area under the graph you fanny
xD
yeah that doesn't help him in any way
It does?...
finding the area under a velocity curve just gives you distance traveled..
that's the point..
Thatās what I need
i thought he's looking for acceleration?
like i said, different question..
ok
Average speed
"we moved on from that" <- I interpreted that to mean "we already know he doesn't need area for acceleration"
ty for the clarification
@vale quarry fucking baghead
@latent pulsar ur a baghead too for not using the fucking graph scale
nonce
Iāve finished
got it?
Sorry Zed I didnāt realize I was keeping you awake
niceone
thank fuck ive got a bangin headache but i couldn't leave a child struggling with maths behind
13.7166666 sounds a little better
no child left behind
how'd you calculate the average speed
Iām gonna leave this, do the other bit tomorrow or Saturday
sound
Btw if you want to see the last question I can send it in
have a good night everyone except you sam fuck you and your fucking squares i hope your items never go in the bagging area in morrisons you wanker
Lmfaoooooo
that hurt me
say that about my fucking squares again knobhead
who got a 9
and guess what i do
fucking squares
fuck you
what's a 9
Lmao
(I just want to interject and say I love the way brits insult each other lol)
we try we really do
makes me think of jason statham yelling angrily
rename urself to trapezium wanker
dang he's 51?
anyways take your 9 and shove it up ur ass at least i have consistency and no fucking bullshit squares
LOL
ok trapezium boy
it only gets fun in further
Arse*
all colleges (or most) have study days right?
what are those
my college takes off the study day for those who do fm
like a day of no class before final exams?
Isnt it like a break day
yeah I've got a study day
ooo lucky bastard
weds last year tues this year
oh my school had classes monday-friday
Lol
but if you're lucky, you could rearrange your schedule to have less than 5 days of classes a week
i had a semester with classes only 2 days a week
yeah our secondary schools r like that
oo big boi's in second year
yeah am doing my exams rn
buena suerte
How are they going
i thought they were already done
Last one tomorro
pretty smooth
oh no not quite
nah
swimmingly
i had my progression exams last month
I've had 3 this week
Well GCSE is
Sort of
goddamn
no not really
college isn't uni
Theyāre just sort of there
lol what
gcses are for 6thform
college is the 2 years before uni
gcse s are the most important thing for all of 2 minutes
A level courses are used for uni
yeah
every time i say college, I mean uni, btw
ye
@marsh linden donāt reveal stuff like that 
I have
sorry strager
5 days of class
we know, you americans got us fucked up
Well
But it's best you know it now
Iām going to
okay retard @lucid junco
LOL
um
@marsh linden I know anyway dw xd
gud
@gentle heath Iām gonna have to mute you. Such language is not acceptable in this server.
bruh
Goodbye
a levels are useless too once you get into uni
he gonna slap back hard
sam > /dev/null
No not Sam pls
use every swear word in the book
eh still valid qualifications
sure but like

kinda like the SATs in USA I suppose
no one cares about them once you're in college
uni*
We have SATs
yeah nothing compared to a degree
no one isnt gonna hire you bc u got a b in history a level
Thatās pretty true tbh
Sam is now muted
same
Let this be a lesson
fight me
he escaped
he lives
He survived
I'll mute u irl @lucid junco
uh oh
Maths -> fights dk how but here we are
š³
Errr
i still have a headache but im here for the banter

banter is unmissable
Incel lives matter
Hi brits
hello spanish prsn
oioi pasta

wtf is that testicle
okay boomer
say that to dew
who's a ball
he's shrivelling on himself
like an apple
lmao
mr ride
what does that say im gringo
Translator boi here
it says if you understand this give dew a hug
but im pretty good
seriously tho i cant read the yellow
Translator peter where
veracruz
it says dews a nonce
Where did dew appear from?
fucking knew it
Thatās ok Veracruz isnāt even worth anything
from the big bang
@gentle heath you are literally the most British person here
People from Veracruz are crabs
And you Zed
northern*
soy un cangrejo
What about me
ur just a twat
wow
what about me
did the role give it away
you canāt talk to me like that
Sorry Zed
Iāll tell on you
muted
shut the fuck up boomer
fuck off u wanker you're not powerful enough to stop me
āhave a good night everyone except you sam fuck you and your fucking squares i hope your items never go in the bagging area in morrisons you wankerā can we just reflect on this?
any of you degenerates want to vc?

yeah
Me
Muppets these days smh
that was very nice tbh zed
Letās go
Not rn Nex
See you in general
am proud of u for that
SEE YOU
if i do say so myself
some of your best work
The Morrisonās part really made it
the real iinsult
Me neither
is shopping at morissons
I might join but not talk
id say asda ftw but im lazy and morrisons is closer
poor cunts imagine not having a tesco
sh
lmao
And Nex
hi
Nex wtf you sound so different to what I thought
sick
damn my internet is so shit i cant even connect
i was just gonna listen in on ur voices and leave smh
gg
