I hope you do badly LAYYEMAO
(AunionB)'=A'intersectionB'
Tell us the questions to see how difficult it was.
[math] \{a\}\neq\{a,a_{{}^{{}^{{}_{\!.}}}} \} [/math]
How to make the product of an arbitrary number of sets
[eqn]\{x:x\not\in x\}[/eqn]
It's essential to know set theory.
Okay guys,
I think I aced it. Some sample questions were:
Prove 1+2+3+...+n=(n(n+1))/2
Is [a] o-plus [b] = [a+b] a well defined operation
Prove sqrt(2) is irrational
Prove de Morgan's law
kek what sort of exam is this
Intersection
Union
Cardinality
Powerset
Emptyset
1-1 Correspondence
>set theory
It looks like intro to proofs what the fuck.
>Cardinality
useless concept desu
We learn basic set theory but mostly proof methods in this class. It is to set us up for our advanced calc class.
Are you a George Mason student? I ask because only a few places have "advanced calc" in place of true real analysis.
What are large cardinals
Are you in third grade?
>set theory
Is this a joke?
>Prove 1+2+3+...+n=(n(n+1))/2
>Prove sqrt(2) is irrational
>set theory
What the fuck????
That has barely anything to do with set theory?
That it's pointless to try to assign names to every point on a spectrum
i can do these two proofs, never taken a class in '''set theory'''', physics major. Barely done any maths modules. Is maths a fucking meme subject?
>Is maths a fucking meme subject?
Not if you go to a non-meme uni/country.
We also have a set theory course, but these questions are settled in the first semester and have absolutely nothing to do with our "set theory" course which is more advanced math.
>Unions and Intersections are the only things I know about set theory
