An animated introduction to Fourier series
A visual introduction to Fourier Series
In this series, we will start with a brief recap of some of the math concepts related to the circle, including trigonometric functions like sine and cosine. We can always add more terms to the partial sum to help the red dot in its holy mission, improving the approximation until nobody cares anymore. To better visualize what’s happening, let’s look at a Fourier Series Machinery and how the circles move to create beautiful practical patterns.
