comment Difference between boundary point & limit point.
My apologies. I thought $X$ was the set in question, not the entire topological space.

comment Difference between boundary point & limit point.
Yes, that's true. From a purely answer-the-OP's-question point of view, it helps to make a distinction, but from an educational point of view (for others who might later stumble upon your answer) it should be technically correct.

comment Difference between boundary point & limit point.
Let it be known that boundary points need not be members of $X$. For example, the set $T=(0,1)$ has two boundary points: $0$ and $1$, even though they are not members of $T$.

What is $K$? Is it a function of $x$?

comment Why I can't calculate $0*log(0)$ but can $log(0^0)$
Good explanation and answer. However I think the statement “any real number raised to the $0$ is $1$” is about as true as the statement “$0$ raised to any real number is $0$.”

Prove $0^0=1$ : )
