... This is referred to as the Null Set or Empty Set. Caution: Do not write the {0} set as the null set. This set contains one element, the number 0. Example 5: To show that 3 “is a element of” the set {1,2,3}, use the notation: 3 {1,2,3}. Note: This is also true: 3 N Example 6: 0 N where is rea ...

... Lecture 2.8. A real number is positive iff there is a positive integer m such that xn ≥ m1 for all n. See Bishop’s proof p.21. 4. We need to be careful in how we think of x ∈ R+ . We need the witness to ∃n : Z+ .(xn > yn ), so we think of the pair < x, n >. 5. Comparing numbers is delicate, we do no ...

Disproving something: counterexamples If we are asked to show that a proposition is False, then we just need to provide one counter-example for which the proposition is False In other words, to show that x P(x) is False, we can just show x P(x) = x P(x) to be True Example: “Every positive inte ...
