\begin{question}
\begin{enumerate}
\item Define what it means for a function to be \emph{analytic} on some open subset of $\mathbb{C}$.\marks{5}
%% Notice the emphasis of the term to be defined.
\interject{Let $s$ be a complex number such that $\Re(s)>1$. Define $\zeta(s)$ to be the
number:
\[\zeta(s):=\sum_{n=1}^{\infty} n^{-s}.\]
(In all cases, $n^{-s}$ means $\exp(-s\log n)$, with $\log n\in \mathbb{R}$.)}
\item State how to define the analytic continuation of $\zeta$ to all of $\mathbb{C}\setminus\{1\}$.\marks{10}
\item Show that all non-real zeros of this analytic continuation have real part equal to $\frac{1}{2}$.\marks{10}
