## Coosje van Bruggen

Usually, "by request" is accompanied by an OTRS ticket number in the edit summary or on Talk. Is there any such thing you could add to the Talk page so folks don't try adding these particular images again? Thanks. --Lexein (talk) 02:22, 10 November 2012 (UTC)

Thanks for the remark! I added a section with corresponding references to the Talk:Coosje van Bruggen page. — Mikhail Ryazanov (talk) 02:51, 10 November 2012 (UTC)
Thank you for the excellent response. That DMCA takedown was rather extensive - shall I help note on article Talk for the other deleted images? --Lexein (talk) 07:43, 10 November 2012 (UTC)
Sure. I just saw that DMCA notice accidentally and was making fun of it, but if you can do anything more serious, please go ahead. — Mikhail Ryazanov (talk) 08:54, 10 November 2012 (UTC)

## why jpeg?

Good point. I have uploaded a new png-version, and made a change to the article on which the image resides. Cheers - DVdm (talk) 07:06, 12 April 2013 (UTC)

## (moved)

Dear Mr Ryazanov: I saw your modification to Multivariate normal distribution dated 25/4. You wrote that "^k was missing in normalization factor" but actually the ^k should not be there, since the $2\pi$ is inside the determinant, and $|2\pi\Sigma|=(2\pi)^k|\Sigma|$, so there's no need for an additional ^k. Hence, I removed it. Cheers. YetAnotherBunny (talk) 14:47, 30 April 2013 (UTC)

## Cubic equation picture

Looks good. Can you please upload it to Commons? Then {{vva}} can be added to the old PNG version there. — Mikhail Ryazanov (talk) 05:14, 12 May 2013 (UTC)
I think i did that right. Olin (talk) 12:58, 12 May 2013 (UTC)
Now — yes. :-) I marked the local file as duplicate and added {{vva}} to the old PNG and JPEG versions. — Mikhail Ryazanov (talk) 03:33, 13 May 2013 (UTC)
This one is next! Olin (talk) 14:55, 13 May 2013 (UTC)
