Mathematical equations do not display correctly
The image at right is a screen capture of part of the article Cauchy–Schwarz inequality. Notice that the last few symbols of the equations are not displayed. Can someone help me correct this problem? Thanks very much for your help!--老陳 (talk) 05:32, 23 March 2017 (UTC)


 * It displays correctly on my ipad screen. Loraof (talk) 15:34, 23 March 2017 (UTC)


 * I am using Windows 10 with Microsoft Edge browser on my PC.--老陳 (talk) 23:29, 23 March 2017 (UTC)


 * I just tried using that setup, and it renders fine for me. Don't know what to tell you.  Deacon Vorbis (talk) 04:54, 24 March 2017 (UTC)


 * Is here the right place for this kind of questions?--老陳 (talk) 05:13, 24 March 2017 (UTC)


 * The question has the word "Mathematical" in it. I guess it is related to the expression of Mathematical concepts. 148.182.26.69 (talk) 05:22, 24 March 2017 (UTC)
 * Per WP:?, questions about Wikipedia editing should be placed at Help Desk (or a more specialized venue if you know where to go); reference desks are for questions about the world outside Wikipedia edition. For that particular question, the best venue is either Reference desk/Computing if the problem is on your end (as it seems to be), i.e. your computer does not display the equation, or the help desk if the problem is that the Wiki-code on the page is incorrect and causes display problems; it is not a big deal either way, I think.

 * I have no idea what the reason might be, but try going to the Preferences page Appearance tab (Special:Preferences) and choose 'PNG images' if you use 'MathML'. --CiaPan (talk) 14:25, 24 March 2017 (UTC)
 * I tried to change it and the display problem went away. So, I think there's a bug in the 'MathML' option.  Thanks for the help.--老陳 (talk) 00:00, 25 March 2017 (UTC)

Reflection formulas for the Gamma function
We have
 * $$\begin{align}&\Gamma\Big(1~+~x\Big)~\cdot~\Gamma\Big(1~-~x\Big)~=~\frac{\pi x}{\sin\pi x}\\\\&\Gamma\left(\tfrac12+x\right)~\cdot~\Gamma\left(\tfrac12-x\right)~=~\frac\pi{\cos\pi x}\\&\Gamma\left(\tfrac14+x\right){\bigg/}\Gamma\left(\tfrac14-x\right)~=~\pi^{2x}\cdot\frac{\zeta\left(\tfrac12-2x\right)}{\zeta\left(\tfrac12+2x\right)}\end{align}$$

where the latter is nothing else than the functional equation of the Riemann zeta function. I was wondering whether yet another similar relation might also exist, involving $$\Gamma\left(\tfrac18\pm x\right)$$ or $$\Gamma\left(\tfrac13\pm x\right).$$ — 79.113.251.53 (talk) 11:12, 23 March 2017 (UTC)
