How do you show that the closure of [a,b] is not closed in C0[a,b]?
C0[a,b] is .. the space of continuous functions with compact support..?
If the answer is affirmative then i cant help you, [a,b] is not a subset of C0[a,b] .
If the answer is negative then i cant help you since i dont know what you mean with C0[a,b].
Need context
I think what southprkfan1 thought vinnie100 meant was:What did you think he meant? I don't actually understand what he was asking for.
Prove that is not closed on
where is the set of functions with p continuous derivative on [a,b] and the set of continuous functions
