I am stuck on this one question. It meantions something like R(R^(-1)) can someone explain to me how to read this exactly and what does it mean.

- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:

R^-1 notates the inverse
vagrant iris
U plug the values into R again
vernal cape
how does that change R
well in this case R(-1)B gives the set of all elements of A which make the relation aRb possible
how do I plug that in a R()
vagrant iris
U can plug sets into functions
They give the united result of plugging them individually in
vernal cape
hmm
lemme try and get back to you
@vagrant iris that helped a lot thank you so much

<@734323423475662888> I can help if you made progress
yeah please do
tame bough
So what is your progress?
Show me your work
So I know where you stand/have difficulties
@vernal cape
vernal cape
its a mess
wait a min
I am really new to proofs so not really good at writing em
very bad
vernal cape
it will be R(R^-1(B)) = B is a contingency in the first page
tame bough
Now just to choose the right thing
vernal cape
Now just to choose the right thing
right thing in what terms
tame bough
a, b or c
vernal cape
oh got it
vernal cape
ig its the 3rd one which is the tautology
vernal cape
yeah
tame bough
Gg
vernal cape
well my proff told me to give examples to prove a contingency and to give general proofs for Tautology and Contradictions
thats what I am trying to do
I was really confused my all the symbols and stuff earlier
need to practise more to get comfortable with them
thanks for verifying it tho
tame bough
Welcome. Have fun! 🎩
