Homework Statement
For a metric space (X,d) and a subset E of X, de fine each of the terms:
(i) the ball B(p,r), where pεX and r > 0
(ii) p is an interior point of E
(iii) p is a limit point of E
Homework Equations
The Attempt at a Solution
i) Br(p) = {xεX: d(x.p)≤r}
ii) Br(p) = {xεX: d(x.p)≥r}
iii) I do not know the answer to this at all.
I do not know if the first two parts are correct either so I would appreciate any help given.
