- Is it true that if C is a nonempty closed subset of R and x is a point not
- in C that there exists a point c in C that is closest in C to x.
-
- i.e. such that: |x-c'| >= |x-c| for all c' in C.
-
- If it is true I would appreciate if someone could give me a proof
- of the result.
-
- Thanks in advance.
