comment What does Elim $\land$ actually eliminate
It's hard to be sure, because I don't know for certain what rule you mean by “Elim $\land$”, but the answer is probably “Neither of the things you said is correct.”

comment In classical logic ~~p -> p? Intuitionistic?
$\sim(\sim p)\to p$ is classically valid but not intuitionistically valid. $p\to \sim(\sim p)$ is both classically and intuitionistically valid..

comment What exactly is an “analytic function”?
Yes, you have it exactly right. The point isn't that you would represent a non-analytic function with a power series; as you observed, that would be silly. The point is that some functions can't be so represented, and it's useful to have a special term to distinguish functions that can be so represented from functions that can't.
