Find each of

a)The reflexive closure of T

b)The symetric closure of T

c)The transitive closure of T

Give your answers either as sets of pairs or as diagraphs

As I said with the previous question...

I apologize now for the fact I have not done any working out simply because I don't have a clue how to even start it! I'm trying to learn it now as I go along but don't have much time so thought I would look for help on here as well as the text book (which isn't making sense right now) so I have two points of view on the question. I'm stuck on two more questions which I will post on sperate threads too. Thanks for any help it's much appreciated.
