For functions that are not periodic, the Fourier series is replaced by the Fourier transform. 4 References • https://en.wikipedia.org/wiki/Joseph_Fourier • https://www.britannica.com/biography/Joseph-Baron-Fourier • https://famous-mathematicians.com/joseph-fourier/ • https://www.encyclopedia.com/people/science-and- technology/mathematics-biographies/baron-jean-baptiste- joseph-fourier • Newsletter of the european mathematical society, European Mathematical Society, issue 113, September 2019. • https://mathworld.wolfram.com/FourierSeries.html • https://www.lindahall.org/joseph-fourier/ • https://news.cnrs.fr/articles/joseph-fourier-is-still- transforming-science 5.
