But what is a Fourier series From heat flow to circle drawings, DE4

Fourier series, from the heat equation to sines to cycles. Home page: Brought to you by you: 12 minutes of pure Fourier series animations: Some viewers made apps that create circle animations for your own drawing. Check them out Thanks to StuartBiocinematics for the oneline sketch of Fourier via twitter. As it happens, he also has an educational YouTube channel: Small correction: at 9:33, all the exponents should have a pi2 in them. If you re looking for more Fourier Series content online, including code to play with to create this kind of animation yourself, check out these posts: Mathologer The Coding Train Jezmoon F
