{\bf Theorem 1 (Residue Theorem).}
Let $f$ be analytic in the region $G$ except for the isolated singularities $a_1,a_2,\ldots,a_m$. If $\gamma$ is a closed rectifiable curve in $G$ which does not pass through any of the points $a_k$ and if $\gamma\approx 0$ in $G$ then
\startformula
\frac{1}{2\pi i}\int_\gamma f = \sum_{k=1}^m n(\gamma;a_k) \text{Res}(f;a_k).
\stopformula

{\bf Theorem 2 (Maximum Modulus).}
{\em Let $G$ be a bounded open set in ${\mb C}$ and suppose that $f$ is a continuous function on $G^-$ which is analytic in $G$. Then}
\startformula
\max\{|f(z)|:z\in G^-\}=\max \{|f(z)|:z\in \partial G \}.
