I am sorry. I just did not realized that I was using infinity and not infinite values. Thanks for the discussion.

comment How to find all the pairs satisfying a relation?
Relations are sets having some link within. Here all the points satisfying the equation belong to the relation. Domain being all the 'a' values and Range is all the 'b' values of the relation.Oh, I got it :) Both of them should be equal to the set of real numbers ?

As it has infinite values so shouldn't the domain and range be infinity?

No, there can not be a 'x' whose pair does not satisfy this relation. But still the problem remains about how do I find its domain and range?

comment How to represent the Cartesian product of an infinite set?
Thanks. Can you please help me out with the notations you used? In {a,b:a is a real number and n is 1,2, or 3} what is 'n' and why is there a need to define it?Moreover how would the person know that 'b' is also a real number?

comment How to represent the Cartesian product of an infinite set?
@Qiaochu and lhf: What I mean is that there are infinite terms in a set of all real numbers.Moreover as it includes all the floating point values so it more difficult to represent all of the elements of that set.

I would be thankful if someone could create a Cartesian-Product tag for the community.

comment What does {2x|P(x)} mean?
Should I think that first I have to check the conditions of the preposition and then mark them true for all multiples of 2?
