Example: Polar plot of sine based function

Published 2017-01-01 | Author: Stefan Kottwitz

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This plot was originally made for my blog post on TikZ.de: http://tikz.de/periodisch/

Oder frag auf Deutsch auf TeXwelt.de.

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