User talk:Widener

Welcome!

Hello Widener, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay.

At Wikipedia, new Users do not automatically receive a welcome; not even a machine-generated welcome. Welcome messages come from other Users. They are personal and genuine. They contain an offer of assistance if such assistance is ever desired.

I suggest to everyone I welcome that they may find some of the following helpful — there’s nothing personal in my suggestion and you may not need any of them:

• Introduction
• The five pillars of Wikipedia
• How to edit a page
• Help pages
• Tutorial
• How to write a great article
• Avoiding common mistakes
• Manual of Style

I hope you enjoy editing here and being a Wikipedian! If you need help, check out Wikipedia:Questions, ask me on my talk page, or place {{helpme}} on your talk page and ask your question there. Again, welcome! Dolphin (t) 06:10, 11 February 2011 (UTC)

Could I suggest that instead of writing things like

$1+1+1+...\,$

you could instead write

$1+1+1+\cdots \,$

telescoping sum

Concerning the sum

${\begin{aligned}0&=0+0+0+0+\cdots \\&=(1-1)+(1-1)+(1-1)+(1-1)+\cdots \\&=1-1+1-1+1-1+1-1+\cdots \\&=1+(-1+1)+(-1+1)+(-1+1)+\cdots \\&=1+0+0+0+\cdots \\&=1,\end{aligned}}$

check out the article titled telescoping series. Michael Hardy (talk) 22:50, 20 June 2011 (UTC)

Hello

Hi! I'm curious if you are actively solving problems because you are enrolled in classes or rather because you are working independently studying. It's fine if you don't wish to answer: I'm just curious, and it is not important. Rschwieb (talk) 14:15, 15 April 2012 (UTC)

It is both, actually. It depends on which questions you are referring to. Widener (talk) 12:10, 16 April 2012 (UTC)

"Both" is a good answer, which I half expected at the outset While I'm no longer officially a student, I'm doing a lot of independent reading on physics, tensor algebra, and geometry. Rschwieb (talk) 13:57, 16 April 2012 (UTC)

Wikipedia Help Survey

Hi there, my name's Peter Coombe and I'm a Wikimedia Community Fellow working on a project to improve Wikipedia's help system. At the moment I'm trying to learn more about how people use and find the current help pages. If you could help by filling out this brief survey about your experiences, I'd be very grateful. It should take less than 10 minutes, and your responses will not be tied to your username in any way.

Thank you for your time,
