\textbf{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
%
\[
\mathop{\mathrm{Res}}\limits_{z=a}f(z) = \mathop{\mathrm{Res}}\limits_a f
= \frac{1}{2\pi\mathrm{i}} \int\limits_C f(z)\,\mathrm{d}z,
\]
%
where $C\subset D\backslash\{a\}$ is a closed line
$ n(C,a)=1$ (e.\,g. a counterclockwise circle loop).
