i believe \ in sets is the difference between the elements. so A={1,2,4,6} and B={1,3,4,7}, then A\B={2,6} (elements A has but B doesnt) but i have no idea how it actually means anything here.
idk whats ur cs prof smoking ive never seen shit like this before
my guess is
A1={a, (a), (a, a)}
A2={a, (a), (a,a), (a), ((a)), ((a, a)), (a, (a)), (a, (a, a)), ((a), (a, a))}
and so on
but it makes 0 fucking sense to me
the graph seems to draw a line to every memeber of the set, and if that member is another set u in turn draw the line to all its members and so on
im gonna eat rn and when im done ill try to draw it but im not surei even understood it correctly, shits weird as fuck, did u have than in ur lectures?
isnt A1 just a, (a), (a,a) because A0 is only a? then A2 would just be a, (a), (a,a), (a), ((a)), ((a,a,)), (a,a), ((a,a,)), ((a,a))? i dont know it looks dumb and there are repeats but thats just literally it
no the closest thing to this we did in lectures was the cartesian product, after that we did relations, binary relations, graphs and relational product
a2 is formed of all x, (x) and (x,y) such that x and y are in a1, so what u do is u first take all elements in a1 as x and add them in a2, then take a set with a single memeber x where x is again everything from a1, and then u combine every pair of elements in a1 and put them in a2
1500 students starting computer science with me (including bioinformatics, econ-informatics and games-engineering people, we mostly share almost all lectures though, each of these degrees has 1 module to make it "special")
theres about ~730 students in a full lecture room, the rest are split among 2 other rooms (and watch a livestream, theres a cameraman in the main room) or watch the livestream from home
it can get noisy at the end of the lecture when everybody wants to leave, but whenever the prof asks everybody to shu.t up they do
how big is the board that the student at the very far back can actually see it? do they write anything on the board at all or is it all just projection? and can you actually hear the prof at all?
the prof has a microphone (also used for hte livestream obviously), they write on the powerpoint presentation on their laptops using touchscreens
the seats are arranged in a way that u never have a head in front of u and can see the prof at all times (german engineering PogChamp), the profs are usually very good in general, u could probably understand the lectures without any visual input as well
the bord is huge (i'd say 10 meters x 1.5m) and there are buttons in the front to move the board up and down
Pivo je alkoholno piće koje se pravi od kvasca, hmelja, slada (ječmenog, pšeničnog, ražanog...) i vode. Spada u alkoholna pića sa manjom koncentracijom alkohola (3 - 13%). Jedno je od najstarijih pića koje se koristilo u Egiptu. Danas je veoma zastupljeno u cijelom svijetu, pa i u Bosni i Hercegovini. Pivo se proizvodi u pivarama a služi se u pivnicama, raznim kafićima i kafanama.
Pod pivom se podrazumijeva slabo alkoholno piće, koje se proizvodi u procesu alkoholnog vrenja iz slada, hmelja, vode i pivskog kvasca. Voda je glavni dio napitka i služi kao rastvarač. Slad se dobija od žitarica, najčešće od ječma i daje pivu sastojke ekstrata od kojeg zavisi punoća ukusa i koncentracija osnovnog ekstrata piva.
Hmelj konzervira pivo i daje mu ugodan miris i gorak ukus, dok pivski kvasac izaziva alkoholno vrenje u kome šećer prelazi u alkohol i ugljen dioksid. Pivo je potpuno prirodan i biološki uravnotežen proizvod, pa se s pravom smatra "tekućom hranom". Energetska vrijednost jedne litre standardnog piva odgovara energetskoj vrijednosti jedne litre punomasnog mlijeka.
does this make sense? instead of bracketing x, (x) and (x,y), i use the power function, with prime numbers in hope that the numbers dont collide due to the power function
what the hell is the "power" of a set? i have never heard of that before. or maybe i have but i dont recognize it now because its a different language.
Sure thing, I'm always happy to help my comrades with lesser minds! :)
:)
how do i draw A2\A1 in a graph like it is shown in the middle? i'm genuinely confused by this
human language pls, shits too obscure to understand without reading the task
what even is A2\A1 in this case
i asked a friend of mine whos studying cs in masters and he said "idc i forgot everything right after the exams"))
we define the following sets of tuples a0 a1 a2 this way:
a0 = {a}
...
(a) graphically show the elements of a2\a1
reminder: ((a), (a,(a))) looks like this:
i guess its A2-A1, somethimes its written with a backslash
i have no idea what is graph supposed to represent though, i think understanding whats written in the task will help
i believe \ in sets is the difference between the elements. so A={1,2,4,6} and B={1,3,4,7}, then A\B={2,6} (elements A has but B doesnt) but i have no idea how it actually means anything here.
yeh, its a2 without a1, but i got no clue how to do this operations on those 2 sets since the content is only shown implicitely
idk whats ur cs prof smoking ive never seen shit like this before
my guess is
A1={a, (a), (a, a)}
A2={a, (a), (a,a), (a), ((a)), ((a, a)), (a, (a)), (a, (a, a)), ((a), (a, a))}
and so on
but it makes 0 fucking sense to me
the graph seems to draw a line to every memeber of the set, and if that member is another set u in turn draw the line to all its members and so on

isnt A1 just a, (a), (a,a) because A0 is only a? then A2 would just be a, (a), (a,a), (a), ((a)), ((a,a,)), (a,a), ((a,a,)), ((a,a))? i dont know it looks dumb and there are repeats but thats just literally it
we had the basic version of this in lectures,
i.e. A={1,2,4,6} and B={1,3,4,7}, then A\B={2,6} and this:
i was there in the lecture and i was paying attention, i definetly didnt see sth like this (maybe i should check my notes give me a sec)
well yes what u wrote makes sense, how did u get these results for a2?
i have literally never seen anybody draw those like that before
no the closest thing to this we did in lectures was the cartesian product, after that we did relations, binary relations, graphs and relational product
a2 is formed of all x, (x) and (x,y) such that x and y are in a1, so what u do is u first take all elements in a1 as x and add them in a2, then take a set with a single memeber x where x is again everything from a1, and then u combine every pair of elements in a1 and put them in a2
im gonna draw a diagram or smth when im done stuffind mself
me before studies:
"hehe pls i want to be in top 2% of 1500 students with a bit of work to get into the honors program and/or get a good job"
me 2 weeks in:
1500 students? is that the entire university or just your faculty/deparment?
wtf is that
so i did this
seems reasonable?
1500 students starting computer science with me (including bioinformatics, econ-informatics and games-engineering people, we mostly share almost all lectures though, each of these degrees has 1 module to make it "special")
Do you even understand shit with 1500 people in a lecture?
theres about ~730 students in a full lecture room, the rest are split among 2 other rooms (and watch a livestream, theres a cameraman in the main room) or watch the livestream from home
it can get noisy at the end of the lecture when everybody wants to leave, but whenever the prof asks everybody to shu.t up they do
holy shit 730? how gigantic is that shit?
this is the smaller one, the one i was talking about is a bit bigger and has no "balcony", couldnt find a good pic on google
lmfao
how big is the board that the student at the very far back can actually see it? do they write anything on the board at all or is it all just projection? and can you actually hear the prof at all?
the prof has a microphone (also used for hte livestream obviously), they write on the powerpoint presentation on their laptops using touchscreens

the bord is huge (i'd say 10 meters x 1.5m) and there are buttons in the front to move the board up and down
ok i think thats the way to do it
I hope its simple enough for your feeble mind to comprehend. :)
the projection (as shown in the image) is very big as well, it covers pretty much the whole wall on the back (~5x7m)
shouldnt (a) be removed as well? all duplicates of (a) should be removed since they are in a1, no?
right, my bad
thank u very much that helps a lot
mmm calculation |a3| and |a4| sure seems like some fun
i did a3 by hand but a4 isnt possible i think, u think its hard to write a java program for this?
if theres an in-built set type in java why not but i think ull spend less time writing it out on paper than writing a program
the issue here is finding a common rule to count the elements from a set a1 and calculate the amount of elements a2 will have
no its not possible to do a4 on paper i think, unless i want it to take 2 pages
a4 is a2, (a2), 28 combinations, (a2,(a2), 28 combinations) and all possible combinations
i mean u still gotta write it out on paper dont u?
no, only need to write down the amount of elements in a4

oh its easy then
|A(n+1)| = 2*|A(n)| + C(|A(n)|, 2)
for A(3) its 2*9 + C(9, 2) = 18+36=54;
for A(4) its 2*54+C(54,2) = 108+1431=1539.
yeah well writing 1539 members out would be pretty problematic ;););) hehe ~<3 *rawr*
Ayy lmao
does this make sense? instead of bracketing x, (x) and (x,y), i use the power function, with prime numbers in hope that the numbers dont collide due to the power function
dude i dont know java and u dont need it just to calculate the power of ur sets, there is a formula
huh
what the hell is the "power" of a set? i have never heard of that before. or maybe i have but i dont recognize it now because its a different language.
whoops almost roasted my pc because of a while loop
