Exactly the kind of channel I am looking for: great content about special functions, we meet so many of these in physics problems (I used the Bessel decomposition of exponential during my Phd for a Lock in amplifier signal processing) and here you demonstrate easily the relations involving these functions, thank you.

Amazing explanation! Will you make videos about how to obtain the recurrence relationships?

Thanks for this great video! Where can I find the video mentioned in the end of this video? about the integral representation of the bessel's function of the first kind.

2:41 small question, when can we switch up the sums?

You did not "derive" it. You verified it. A more challenging task would be to show how one might "discover" the generating function in a non-magical way.
