🔗
Shows up when trying to solve 2D wave equation on a circular domain in polar coordinates with separation of variables, where we have to decompose the initial condition in termes of a fourier-Bessel series, exactly like the Fourier series appears when solving the wave equation in linear coordinates.
🔗
For the same fundamental reasons, also appears when calculating the Schrodinger equation solution for the hydrogen atom.
