Introduction to Set Theory (Discrete Mathematics)

[@yamatanoorochi3149]

A bunch of neat little details that my professors skip over because they don't deem it relevant to the curriculum... So neat, it makes the video that much more interesting Learning maths outside of the academic context makes it easier to like

Thank you...You make Math and English easy to understand! You save my life.

I was trying to do a self study of proofs from the book of proof and I’m glad you have this playlist! Its already helping me so much.

Great you made a playlist for discrete mathematics!

[@dannycollins5698]

You are amazing and make my life better!

Hi, is it convenient to review this playlist before to do the Udemy course in Abstract Algebra: Group Theory?

Thank you for this video

My pleasure!

Great vid Math Sorcerer! Im teaching myself set theiry from a book by Chatles Pinter and got a bit stuck with a proof....wondering if you or sbyone could help? Im trying to show that the Russell class {x: x forsnt belong to x} is a proper class and therefore not a set. My intuition tells me to do this by contradiction by assuming this class is a set, and so its a member of some other class...?

Hi sir its sufficient for olympiads level quetion

we need for cardinality proofs!!!

If U = {all people) then Imagine x e U | x living life in peace. Sorry, couldn't resist!

12 ads are alot for any video...

Haha wow that many

[@jonathanstudentkit]

actually some things are wrong, e.g. it is wrong to define i as sqrt(-1), since in the complex field, there are exactly n solutions to z^n = c, in this case n=2, c = -1, hence the definition is unclear. Also methodically the approach is bad, since i*i = -1 is more of an implication of the definition of *: C x C -> C if we set i = (0,1) \in R^2.

Definition of "collection"? 😂
