Homework Statement
Show that if K is compact and F is closed, then K n F is compact.
Homework Equations
A subset K of R is compact if every sequence in K has a subsequence that converges to a limit that is also in K.
The Attempt at a Solution
I know that closed sets can be characterized in terms of convergent sequences. Am I suppose to use that to prove the question?I really have no idea how to do this question.
