... in which case there is a sequence hn ↓ 0 and numbers e > d > c such that ψ(hn ) > e for all n. Furthermore, since ψ is continuous on R/{0}, there exist numbers ln < rn with ln → 0 such that for every n ≥ 1, ψ(t) > d for all t ∈ In ≡ (ln , rn ). In light of (?), there can be no t > 0 such that the s ...

Functions
... A function or map is often seen as a rule that associates, to each element of a set A, exactly one element of a given set B. Formally, this can be expressed as follows: Let A and B be sets. A function from A to B is a set f of ordered pairs of elements (a, b), where a ∈ A and b ∈ B, so that each ele ...
