Bonjour,
j'ai ressayé de dessiner un demi-cercle pour mes résidus et l'intégrer dans un document latex en .png. Pas terrible le résultat, pourriez vous m'aider ?
\begin{tikzpicture}
\draw (1,0) arc (0:180:1)
\draw (\sqrt{3},\sqrt{3}) node[right]{$\Gamma_1$};
\draw (\dfrac{1}{3},0) node[below] {$\Gamma_2$};
\draw (1,\dfrac{1}{7}) node[below] {$Ri$};
\draw (-1,0) node[below] {$-R$};
\draw (1,0) node[below] {$R$};
\end{tikzpicture}
\begin{tikzpicture}
\draw (1,0) arc (0:180:1)
\draw[->] (0,0) -- (\dfrac{1}{3},0);
\draw[->] (1,0) -- (\dfrac{\sqrt{2}}{2},\dfrac{\sqrt{2}}{2});
\draw (\dfrac{\sqrt{2}}{2},\dfrac{\sqrt{2}}{2}) node[right]{$\Gamma_1$};
\draw (\dfrac{1}{3},0) node[below] {$\Gamma_2$};
\draw (1,\dfrac{1}{7}) node[below] {$Ri$};
\draw (-1,0) node[below] {$-R$};
\draw (1,0) node[below] {$R$};
\end{tikzpicture}

\draw (0,0) -- ({sqrt(2)/2},{sqrt(2)/2});
paspythagore a écrit:je vais essayer de m'y mettre. Lequel est le plus simple ?
\begin{tikzpicture}
\draw (1,0) arc (0:180:1);
\draw (-1,0)--(1,0);
\draw[->] (0,0) -- (1/3,0);
\draw[->] (1,0) -- ({sqrt(2)/2},{sqrt(2)/2});
\draw ({sqrt(2)/2},{sqrt(2)/2}) node[right]{};
\draw (1/3,0) node[below] {};
\draw (1,1/7) node[below] {};
\draw (-1,0) node[below] {};
\draw (1,0) node[below] {};
