Lecture 15: Orthonormal Bases and Fourier Series

1:16:02

Description: We prove some important identities for Hilbert spaces, such as the Fourier-Bessel series and Parseval’s identity. We explore a close connection to Fourier analysis, defining Fourier coefficients, series and the Cesaro-Fourier mean.

Instructor: Dr. Casey Rodriguez
