Given a metric space [itex](X,d)[/itex], an element [itex]a \in X[/itex] and a real number [itex]r>0[/itex], let
[itex]A:= \{ x \in X | d(a,x) < r \}, C:= \{ x \in X | d(a,x) \leq r \}[/itex]
i need to show [itex] \bar{A} \subseteq C[/itex].
The definition of the closure of [itex]A \subseteq X[/itex] is
[itex]\bar{A} = \cap_{C \subseteq X closed, A \subseteq C} C \subseteq X[/itex]
*i wanted that writing under the intersection sign but can't do it can someone help me with that LaTeX code?*
anyway, I'm at a complete loss as to waht to take the intersection of...
