SUMMARY

An epsilon-disc in R^n is path-connected, meaning any two points within the disc can be connected by a continuous path. To demonstrate this, one must define a continuous function f over the interval [a,b] such that f(a) = x and f(b) = y for any two points x and y in the epsilon-disc. A straightforward approach is to construct the path through the center of the disc, ensuring that the function remains continuous throughout the interval.

PREREQUISITES
  • Understanding of epsilon-discs in R^n
  • Knowledge of continuous functions and their properties
  • Familiarity with path-connectedness in topology
  • Basic concepts of real analysis
NEXT STEPS
  • Study the definition and properties of path-connectedness in topology
  • Learn how to construct continuous functions over intervals
  • Explore examples of epsilon-balls in R^n and their geometric properties
  • Investigate the implications of path-connectedness in higher-dimensional spaces
USEFUL FOR

Students of mathematics, particularly those studying topology and real analysis, as well as educators seeking to clarify concepts related to path-connectedness in epsilon-discs.

Homework Statement



I'm asked to show that an epsilon-disc in R^n is path-connected.

Homework Equations





The Attempt at a Solution



I can kind of understand in my head why it must be, but I literally have no clue how to begin a rigorous attempt at this. I know I need to define a continuous function over [a,b] with f(a) = x and f(b) = y for any two points x,y in the epsilon-disc, but I am not sure how to define this function. Any help would be much appreciated.

What you need to show is that there is a path connecting any two points in a ball. Define a path explicitly. Go through the center if that makes it easier.
