General DiscussionAyy lmao

yea theres one event on 15th with free beer for the whole university, will see how that one goes

its less about team building tho, just getting drunk with music, probably ppl will move to clubs after that (partys from 7 pm to 10 pm or sth)

lul alenari where do u study

hahaha

which one i mean? the "не пту а колледж" sort of university?

at твоя мать коллежд

cy ka

gotta be quite an awful college tbh

нет
полноценный универ со всеми вытекающими
просто двух долбоебов перваков оторвали от сиськи, они пошли на пати и набухались как "настоящие студенты)))"

про девку не в курсе, мб байка

an alcohol enema sounds like one of those things that suck in any possible way, regardless of the outcome

жаль если так :)

one girl on our welcome party got hospitalized thanks to alcohol too afair

тебе бы хотелось видос с места преступления?

da

i dont know why people are so obsessed with alcohol anyway. after some time they are drinking for literally no reason other than to be "manly" or w/e. its dumb. and the worst is its so fucking expensive.

жертва > видос

how is alcohol expensive, a bottle of vodka for 6€ can kill u (or me, becaus eim a lightweight)

no reason other than to be "manly" or w/e

fucking expensive

man ppl still screaming outside but im too lazy to cehck ZZZZZZZZZZZZZZZZzzzzzzzzzzzz

the good stuff can be expensive, no doubt but no student will spend money on that they cant even afford food

why does the quality matter? i usually only have to take a few disgusting shots to be completely drunk, and/or u can mix shit with orange juice so u dont taste it that much anymore

even just a memory of the taste of vodka mixed with orange juice causes disgust

how is this used in proofs?

for any x in R x^2 is greater than 0
such a x exists that x^2=5

i dont understand the question

but why is the a on its head and why is the e mirrored

they drunk?

u retarded?

mirrored E means "exists such a"
reversed A means "for any"

theyre quantors, A for "all", E for "exists"

A x means "for all xes ..."
E x means "such an x exists ..."

ye guess the jokes about my states high school graduate exams being a joke is true

its much more comfortable to use symbols than to right sentences that look extremely idiotic on paper

lmao spunki what was y'all doing in high school man

Gib fur die Aussage ̈ ¬(∃x∈Z : x 2 = 5) eine aquivalente Aussage an, die
keinen Existenzquantor enth ̈alt (Allquantoren sind erlaubt. . . ). Hinweis: ein
negierter Allquator entspricht einem Existenzquantor und umgekehrt.

state an equivalent statement for the statement ¬(∃x∈Z : x 2 = 5), that does not contain a existence-quantor (allquantors are allowed) tip: a negative allquantor equals a existencequantor and vice versa

what to do here, dont i just have to get rid of the brackets

are those 2 equivalent? and why

u have to rewrite it with another quantor instead of mirrored E in such a way that the meaning would be the same, as far as i understood

hell no, they are not equivalent.
if R stands for rational numbers, 2nd one is just not true

ure literally told what to do man

for any X there exists such an Y that x=y (always true for any R as x is part of R and u can take Y=X which is part of R by default)

and

there exists such an x, that for any y x=y <= absurd in case R consists of more than 1 element (type of elements)

¬(∃x∈Z : x 2 = 5) => there isnt such an x that x^2=5 => for every x x^2=/=5 => [for all]x∈Z : x^2 =/= 5

im 99% sure R stands for real numbers
Q = rational and this set of numbers is almost never used anyway

i think i need a dictionary for this one^

thank u guys i got it now

yeah i think r is real numbers, but what triple said is right anyway

in any case u r right, i am extremely bad in english terms for maths cz thats the only course we had fully in russian

i am extremely bad in english terms for maths

i'm having PTSD triggers reading these last pages

the following statements are proposed:

1) every student wants to have good grades

2) no student studies for boring exams

3) every exam that does not contain math is boring (XXXXDDDD le funny PROF!! xD)

4) every student that wants to have good grades, but didnt study, has to rely on their luck

prove: if no exam contains math, the students have to rely on their luck

usually when i dont know the term(90% of the time) and it isnt obvious what i do is put in into ggl translate, then if it doesnt yield anything menaingful i google it and as a last resort i go to wikipedia and click the articles english version

what sort of task is this
are u suppose to say
exams have no maths => considered boring and no one studies => acc. to 4) everyone rely on luck

or do u need to use quantors

btw is it fine to argue using WORDs in a math exam? the exercise i just wrote down here seems so simple to answer in words, but i have no idea how to do this formally/mathematically

i dont google shit cz opening multiple pages simulatenously on ipad fucks it up, so i just rely on my luck and post crap expecting everyone else to guess correctly what i meant
