Thankyou so much it helped me for my DM exam

[kilrati]

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

[huntergaming]

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)

[Mauri]

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

[ebrimagajaga]

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 ???

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

[carlazuritarubindecelis]

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

thank you so much everything makes sense now

[শূন্যপথেরবালি]

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

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