One way to prove this (which I have seen) is via a theorem which proves that if a sequence of functions converges uniformly to , then is continuous. And clearly it is ... Webbn) converges to f (as n → ∞) uniformly on E if, given any ε > 0, there exists n 0 such that for all n ≥ n 0, f n ε-approximates f on E. That is, f n(x)−f(x) ≤ ε for all x ∈ E. 10.1. If (f n) converges to f uniformly on E, then it converges to f pointwise on E. Proof. This follows at once from the definition with x fixed. 1

WebbComparison. Pointwise convergence means at every point the sequence of functions has its own speed of convergence (that can be very fast at some points and very very very very slow at others). Imagine how slow that sequence tends to zero at more and more outer points: 1 n x 2 → 0. Uniform convergence means there is an overall speed of ...
