How to Prove a Relation is an Equivalence Relation

[@Joel-js2gk]

This guy teaches me in 5 minutes things that I've struggled to understand after hours of studying teacher's notes. My teacher is actually really good for the most part but I think the majority of teachers struggle with over complicating matters. Or maybe I just don't pay enough attention in class 🤣

[@Sigmafemale..14]

Obviously both came to the conclusion bruh

[@erjon6569]

This guy is the most American looking person I've ever seen Thanks by the way 🙂

[@TheMathSorcerer]

Lol

[@isabelamaro7722]

Oh my gosh! You thought better than my professor! I love that you repeat everything multiple times and show where you got it from!

[@jessesambro9535]

did you do a line of coke before this video. Good video tho

Thats the best thing about this guy XD

[@TheMathSorcerer]

Lol

[@gerechte1]

Can you please start teaching at my university? The current prof even looks just like you but with 10 hours less sleep

[@TheMathSorcerer]

Lol

[@haleyanderson2258]

lol

[@Ekkos_Baked]

finally someone who knows what they're talking about and also has an accent i can decipher

[@bingusdingus8239]

Thank you so much, as someone with adhd you were able to actually keep my attention!!

[@TheMathSorcerer]

success!

[@wytewolf77]

Tiger King is a smart cookie, good vid, cheers.

[@raminhussain2740]

Goes straight to the point, well explaned I love it. Keep up the amazing work!

[@abrarrahman6302]

Really great explanation. Thank you. Great teachers like you make studying worthwhile.

[@TheMathSorcerer]

aww thanks man!

[@liem8687]

u just saved my assignment, thankyou

[@realyours643]

the explanation was really good, i watch it while i was laying down, but it got to my brain. really great explanation, thank you sir, keep doing your hard work💪

[@TheMathSorcerer]

Awesome

[@Ali124hdkflc]

Currently learning this stuff in my theoretical foundations class haha. Good stuff man, you always put out great content. How did you feel about these when you were first introduced to them?😅

[@TheMathSorcerer]

I didn't understand what a relation was at first, struggled hard lol

[@Sigmafemale..14]

@@TheMathSorcerer Not bad cos every master was once a beginner

[@S.edu2023]

Thanks

[@nandinichaurasiya8362]

Nice way of explanation, thanks a lot😊😊

[@דניאל-ט9ד]

nice to see exotic joe finally learned math

[@gpiludu]

Thanks, Sorcerer Cowboy. This was a good explanation.

[@TheMathSorcerer]

thank you!!

[@LeVraiment]

Nice video. I also discover that we can prove the transitive property by adding a + d = b + c and c + f = d + e.

[@TheMathSorcerer]

yup:)

[@ralphcastro8661]

this is way better than how my prof explained this topic

[@Fearnotsforlove]

This was very very helpful! Great method of teaching

[@Jacob-rg8fj]

thx for the video, keep up the good energy

[@XxYoShIkOgAkIxX]

Coke is your friend lol. Nice video, I see you have fun doing what you are doing :)

[@droidman425]

Thank you very much sir love from India ❤

what a knowledge man

[@TheMathSorcerer]

Thx

[@JamesBrodski]

Amazing video! Thank you so much.

[@Thegamer-kf8zz]

Awesome video!!!!!

[@TheMathSorcerer]

Thanks!!

[@philmccavity]

Makes me feel better watching math pros get confused doing proofs.

[@epicblubber]

This helped a lot thanks man. Nice hat by the way!

[@TheMathSorcerer]

Excellent !!

You are the best!

[@Hi_Brien]

Wild, you used to look like that?

[@TheMathSorcerer]

LOL wow yeah that facial hair, humm, I wonder if I should grow it back haha

[@Hi_Brien]

@@TheMathSorcerer so right now I am working with an equivalence relation. Specifically I have to show that bijectiveness defines an equivalence relation on sets. I can think of a few bijective relations that are not equivalence relations though, simply because of reflexivity, f(a) = a means the only function that works is an identity function like i: A->A, is there some kind of misinterpretation I am doing?

[@Hi_Brien]

@@TheMathSorcerer My current thought which I have very little faith towards is just showing that ~ is bijective? Is that what the prompt "prove that bijectiveness defines an equivalence relation"

[@Hi_Brien]

Update: The actual prompt was isomorphism defines an equivalence relation. I just renamed isomorphism wrongly in my head.

[@jeboitonny1901]

Thanks for this vid. It helped me a lot

[@TheMathSorcerer]

Glad it helped!

[@bestdeals-amazonus7779]

Amazing! Thank you!

what a great video

[@zeenatreddy7692]

this video + these comments made my day lmao, loved it. ahh thank you!

[@TheMathSorcerer]

I'm so glad!

[@natholdelessa6369]

Really Helpful Thank you very much

[@saipansmall]

Why do you add the inner and outer elements together? (A,B)~(C,D) becomes A+D=B+C

[@Caarve]

Thank you so much

[@TheMathSorcerer]

You're most welcome:)

[@bunstie5208]

hi, i pretty much have the exact same question but instead of outers + inners its, a+b = c+d. because addition is commutative i believe i can just rearrange to suit my question?

[@lemone9639]

It's 3am, I was about to do three shots of expresso cause I wasn't able to understand this all night and I need to prove a point to my prof at 9. You just gave me an hour of sleep. Thanks

[@Lionfish5656]

What if instead of (a,b) ~ (c,d), you have a + b? I'm trying to follow the video format, but it's very confusing. Perhaps I'm taking way too much meletonin.

[@user-ee4yx2hs3k]

Thank you bro

[@TheMathSorcerer]

Np

[@Jiang2718]

Convert the condition to a-b=c-d, then every equivalent point appears on a line.

[@abelmedina-aispuro3716]

He is awesome

[@sivatharshan]

i understood this and i dont know what it is and what we doing.only i want is pass the exam tomorrow.

[@TheMathSorcerer]

👍

[@sivatharshan]

@@TheMathSorcerer how can we do that for if a-b

[@Caarve]

6:08 LMFAO that facial expression

[@TheMathSorcerer]

LOL

[@ryanraymond8299]

Confuse a function and an equation in front of your professor, and this is the last thing you see.

[@shawnl7966]

Your videos are really great. If I may give my feedback, I preferred the ones that were just a blackboard. I think adding in mental processing of watching a person and all that comes with that is distracting. Goal is just to focus on the math for me.

[@Uax101]

math is a helluva drug

[@itslogic9583]

Well this was fun
