The Fourier series has been used widely to model various physical phenomena. It becomes a core concept taught in mathematical physics courses. To help students understand the concept and interpretation of the Fourier series, we propose the utilization of the Desmos application in the classroom. Desmos has a feature of a graphing calculator that can be used for visualizing a function without programming. With an appropriate teaching approach, the Fourier series can be understood more easily. © 2025 Sociedad Mexicana de Fisica. All rights reserved.
