How prove that the set of irrational numbers are uncountable?
Proof By Contradiction: Claim: R\Q = Set of irrationals is countable. Then R = Q union (R\Q) Since Q is countable, and R\Q is countable (by claim), R is countable because the union of countable sets is countable. But this is a contradiction since R is uncountable (Cantor's Diagonal Argument). Thus, R\Q is uncountable.
