Discrete Math - 9.1.3 Combining Relations

[@farhan-momin]

Thankyou so much it helped me for my DM exam

[@carlazuritarubindecelis7068]

Thank you soooooooo much! You really are amazing at teaching... that's really rare to say. You saved me from my bad teach of DM!

[@ahmedbilal6376]

Thank you for covering this book so well...

[@zhyakoxalid6892]

Thank you very much, These videos are really useful, great presentation and pace

If neither of the original sets have the number 4, how can R have the tuple (4, 3)? In timestamp 11:34

Will composing a relation (over a finite set) with itself always eventually yeild a fix-point?

[@alimul_nishat]

you are lifesaver dude

[@davidruvinskiy6347]

Hello. Is there a video for 9.2 n-ary relations? Thank you!

[@bmenjamint]

You are a life saver!

[@raghidhammoud]

thank you so much everything makes sense now

[@ebrimagajaga4639]

Essentially, would I be right to say that the R1 XOR R2 is the same as (R intersection R2)' i.e (R1 intersection R2) all complement ???

[@শূন্যপথেরবালি]

Thank you..☺ This videos will help me a lot.

[@effendi_j.kamal03]

Is there a video for 9.4?

[@huntergaming7774]

Question though I got a given of {(1,1)(1,3)(2,3)(2,4)(3,1)} How am i gonna map out (2,4)

[@Gottastudyhard-m3b]

Not a relation then. Maybe its a function but not a relation.

thanks a lot great lessons from you!

Hi! This is also Rosen book??

[@SawFinMath]

Yes. Still the 7th edition.

[@Gottastudyhard-m3b]

​@@SawFinMath@11:00 ma'am clarify here, the two sets are not same?

[@ibrahimalmashaleh2009]

what is the answer for R2 o R1!!

[@ibrahimalmashaleh2009]

and why the answer is invalid!!!

[@SawFinMath]

I went through R2 composed with R1 in the video. The answer is valid and I gave it in the video. R1 composed with R2 would be invalid because their sets don't match up. R2 maps to {0, 1, 2} and R1 maps from {1, 2, 3} so this would be invalid.

[@eminj96]

@@SawFinMath at 11:00 you composed the relation by itself but the first R maps to {0,1,2,3} and second R maps from {1,2,3}. The sets are not the same.

[@amadakram5722]

theres a mistake in R^2, R^3, and R^4, the last one shuld be (4,2)

[@Gottastudyhard-m3b]

Correct.
