A = (a,b)
B = [a,b)
C = [a,b]
D = (a,b]
, a,b are real numbers
Which one of these sets is the biggest?
(Proof is not necessary, I only need to know the correct answer)
Ok, thank you.
Another question:
I have prooved that a function converges in all these 4 sets.
I would just like to use the "biggest" of them to show that it converges in the a larger area (like trying to include all the 4 of them, in a sentence) and I am wondering which one to use.
Maybe the set "C" ?
(assuming , ...)
