Hein's Identity? #28

Open daturkel opened 5 years ago

Do you have a source for this equation? I can't find reference to it anywhere on the internet.

\frac{1}{\sqrt{z - \cos \psi}} = \frac{\sqrt{2}}{\pi} \sum_{m = -\infty}^\infty Q_{m - \frac{1}{2}}(z) e^{im\psi}

Looks like I spelled it wrong: https://en.wikipedia.org/wiki/Heine%27s_identity

This problem doesn't seem to be working right for me. Any idea why?

I'm really not sure why this wouldn't be accepted. It's pretty much exactly what the "official" solution is. Have you been able to consistently reproduce this failure? What browser and OS are you using?

I've been using Firefox on Ubuntu 18.04. I've seen this issue several times.
