comment Help show $\lim \limits_{R\to \infty} \frac{1}{{2R}}\int_{-R}^R {\left[ \sum \limits_{n=0}^\infty\frac{{\cos\sqrt n x}}{{1+{n^2}}} \right]dx} =1$
I guess that you should conclude the continuity of $f$ from the first part. And then en.wikipedia.org/wiki/…

comment Is there any standard method for finding the function defined by a Taylor/Laurent series?
You know, most functions are not like $\sin$, $\cos$, $\exp$, and so on (which are elementary functions). There is a taylor series that have not closed form.

comment There exist a sequence $Z_n$ with $Z_n \to Z_0$ such that $\lim_{n \to \infty} |f(z)| = \infty$
If $Z_0$ is pole then $\lim\limits_{z\to Z_0}f(z) = \infty$. If $\lim\limits_{z\to Z_0}f(z) = \infty$ then $\lim\limits_{n\to\infty}f(Z_n) = \infty$ for any sequence $Z_n\to Z_0$.
