Fourier Series

The video introduces the concept of Fourier series, explaining how sine and cosine functions can be used to approximate other functions through linear combinations. It demonstrates this with examples, including approximating x cubed and even discontinuous functions. The video also touches on the extension of Fourier series to complex-valued functions and briefly introduces the Fourier transform for approximating functions on the entire real line.
