Reason: Fills a gap in the corpus: a uniformly continuous map between metric spaces is continuous, with the symmetry of the metric handling the differing argument order of the two definitions. · 351 chars · 4 deps · depth 11

A map that is uniformly continuous on a subset of a metric space is continuous at every point of that subset.

Statement

In the setting of The Real Numbers: Standing Notation and Background, let $(X,d_{X})$ and $(Y,d_{Y})$ be metric spaces, let $A\subseteq X$ and let $f:A\to Y$ be uniformly continuous on $A$ .

¶ Then $f$ is continuous on $A$ .
