Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have problem with understanding of expanding of formula in this video (at 30min 05s), after few second he neglects term (r/R)^2).

For me there is missing factor 2 at second term (in "j" component). Similarly as here at 24min 10s.

If somebody knows what's the matter there...please let me know.

Thank you.
