You can study the GGBScript for details in the [b]Setup[/b] button. In this version I was able to reduce the amount of lists to calculate the [i]Discrete Fourier Transform[/i] with low frequencies.[br][br]Check this tweet to see an animation: [br][br][url=https://twitter.com/jcponcemath/status/1219928096880525317?s=20]https://twitter.com/jcponcemath/status/1219928096880525317?s=20[/url][br][br]This is an adaptation from the amazing worksheet [url=https://www.geogebra.org/m/vexwne6r]Epiciclos e Séries de Fourier (Batman)[/url] made by [url=https://www.geogebra.org/u/hjbortol]Humberto Jose Bortolossi[/url].[br][br]Finally, the GGBscript was significantly improved thanks to the great master [url=https://www.geogebra.org/u/thijs]Thijs[/url]. Now the performance of the applet is better.[br][br]Enjoy!
