Talk:Sophomore's dream

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Cool!

(But this article is not linked-to enough. I'll see if I can do something about that.) Michael Hardy 23:36, 6 February 2007 (UTC)

But why "sophomore's dream"? 24.137.126.62 09:08, 28 February 2007 (UTC)

Agreed... a reason for the name would be good to add. Privong 04:20, 16 March 2007 (UTC)
I'm wondering the same thing. There's probably an interesting story behind it. Roger 18:11, 14 May 2007 (UTC)
I came to the talkpage to see if this was being discussed actually. The etymology would add to the article. Mehmet Karatay 13:00, 20 June 2007 (UTC)
I agree that some etymology would flesh this out a bit. —Preceding unsigned comment added by 143.44.71.171 (talk) 01:28, 1 October 2007 (UTC)
I added something, but I couldn't find an adequate reference so at the moment it's unsourced. skeptical scientist (talk) 05:18, 12 May 2008 (UTC)

[edit] Expression

Wouldn't the second be simpler as follows?

\sum_{n=1}^\infty -(-1)^nn^{-n} = \sum_{n=1}^\infty -(-1)^{-n}n^{-n}  = - \sum_{n=1}^\infty (-n)^{-n}

I feel like the rightmost expression is much better. --Cheeser1 16:17, 9 July 2007 (UTC)

True, but I think the current expression is in the standard form for an alternating series. Roger 16:25, 9 July 2007 (UTC)
It's not though - it starts at a different index. --Cheeser1 01:39, 1 October 2007 (UTC)

[edit] Images

I don't think the graphs of the functions are very accurate - it appears that as x approaches zero, y tends to a value either slightly above or slightly below 1, when the the actual limit should be exactly 1. Maybe someone with good quality graphing software could confirm my thoughts and upload better images? Pscholl (talk) 12:57, 11 May 2008 (UTC)

Agree with Pscholl. It is sufficiently misleading that it would be better to remove these images. AdamWGibson (talk) 05:22, 4 June 2008 (UTC)

I made a more accurate graph showing both functions. If anyone has any suggestions it would not be difficult to fix... Blues shuffle (talk) —Preceding undated comment was added at 01:06, 12 February 2009 (UTC).
