The sine function is a well known periodic function. Choose an argument factor, which doesn’t divide the period well, and add another sine function with a different factor, and you can see a complicated path around the origin.

This plot was originally made for my blog post on TikZ.de: http://tikz.de/periodisch/

Do you have a question regarding this example, TikZ or LaTeX in general? Just ask in the **LaTeX Forum**.

Oder frag auf Deutsch auf TeXwelt.de.

```

\begin{polaraxis}[
domain = -3600:3600,
samples = 4000
]
\addplot[blue!50!black] {1 - sin(50*x/49) - sin(8*x)};
\end{polaraxis}
