The Fourier series is a mathematical tool used to break down periodic functions into a sum of simpler sine and cosine waves. By representing a complex signal as a combination of these basic waves, it becomes easier to analyze and understand its frequency components. This method has wide-ranging applications, from signal processing and image compression to solving differential equations and modeling physical phenomena like heat and sound. 📌Support us - Like/Share/Follow👆❤️ 📩Interested in custo
