Math Animations on Instagram: "Fourier series is a mathematical concept to represent periodic functions as an infinite sum of sine and cosine functions with different frequencies or coefficients. It was introduced by Joseph Fourier in the early 19th century and is widely used in mathematics and applied sciences. Although the Fourier series has infinitely many terms, it converges to the original function under certain conditions. This convergence process makes it possible to simplify complex prob
