A property of PI

The title is not informative. The property in the article is

$\frac{1}{1^2}+\frac{1}{3^2}+\frac{1}{5^2}+\frac{1}{7^2}+\cdots =\frac{\pi }{8},$

which is a trivial consequence of the result in Basel problem:

$\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\cdots =\frac{\pi }{6}.$

Indeed,

$\frac{1}{1^2}+\frac{1}{3^2}+\frac{1}{5^2}+\frac{1}{7^2}+\cdots$

$=(\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\cdots )-(\frac{1}{2^2}+\frac{1}{4^2}+\frac{1}{6^2}+\frac{1}{8^2}+\cdots )$

$=(\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\cdots )-\frac{1}{4}(\frac{1}{1^2}+\frac{1}{2^2}+\frac{1}{3^2}+\frac{1}{4^2}+\cdots )=\frac{3}{4}\frac{\pi }{6}=\frac{\pi }{8}.$

I see no reason why we should have articles on every series which sums to π or some expression involving π. Wikipedia is not an indiscriminate collection of information. See also Talk:Pi#Formula by 64.59.233.88. -- Jitse Niesen (talk) 03:37, 7 April 2006 (UTC)

• Merge to Pi and see what they want to do with it there. If it's notable, then it'll stay. Certainly doesn't seem to deserve its own article. ConDem^Talk 03:52, 7 April 2006 (UTC) Delete per Jitse's comment. ConDem^Talk 06:11, 7 April 2006 (UTC)

  • Comment. In fact, this was put in pi first and the discussion on Talk:Pi#Formula by 64.59.233.88 shows that two editors and myself think that it should be removed. -- Jitse Niesen (talk) 05:58, 7 April 2006 (UTC)
• Delete The purpose of an encyclopedia is to explain. Articles should make their readers more intelligent. Now, math is not my strong suit, so this article makes absolutely no sense to me. If it were better explained, I would say merge it to Pi, but since its not, Im going to vote delete.--Pal5017 06:49, 7 April 2006 (UTC)
