[edit] Re : deletion of The Prophet (book)

Received your message. I'll work on it shortly. - Mailer Diablo 17:27, 16 May 2006 (UTC)

  • Thanks for your message, I've restored the article. It was accidentally deleted as it somehow botched up with another article that was on articles for deletion. If you have any further questions, let me know on my talkpage. :) - Best regards, Mailer Diablo 17:32, 16 May 2006 (UTC)

[edit] Alison Bechdel...

...was wondering on her blog who wrote the Fun Home article here. You might want to drop by and take the credit! :) —Josiah Rowe (talk • contribs) 20:26, 18 August 2006 (UTC)

[edit] Thank You

Great work!! The French article on the cosine law was way better by any standards, I fell bad I can't understand it. I only see the general flow of ideas. Now it is all clear I will read in finer detail, Thanks!!! The determinant is also featured and looks an excellent site in French. Would you like to translate it? I see some geometrical important ideas not represented at all on the English site.Ricardo sandoval 23:41, 12 April 2007 (UTC)

[edit] FYI

Fun Home was recently promoted to Good article status. I was wondering how much work would be needed to bring it to Featured Article, so I've asked for a peer review. I thought you might be interested in seeing what develops. —Josiah Rowe (talk • contribs) 06:28, 3 August 2007 (UTC)

[edit] suggest change

it is simpler to use the x and y coordinates instead of the lengths. i.e.

mark the point where the blue line meets the circle (a,o). Then

cos theta = a
sin theta = o

if the blue line is extended to any length, h.

cos = a /h
sin = o / h

by similar trianges.

now, using pythag theorem you can find that

sin 45 = 1 /(sqrt 2)
sin 135 = 1/(sqrt2)

you can clearly see that

sin 0 = 0
sin 90 = 1
sin 180 = 0
sin 270 = -1

plot a graph of these values to give you the sin wave. (i would do but i dont no how to make pictures on wiki).

if you ever update the page ill write a bit about taylor series for u.

btw, like the matrices idea. u gona put reflections and rotations using trig?

(nb// rads are more elegant than degs.)

[edit] PID

Hi Kai- Do you think that a non-specialist is likely to have any understanding of the current introduction to PID ( even a mathematican from an area not using much algebra) or get a feel for the motivation for their interest? The words you use are correct, for people who know their meaning already, but likely to be a mystery for those who don't. Messagetolove 10:47, 19 October 2007 (UTC)

I read your response on my talk page. I did attempt, back in July,to motivate the interest of PID for the non-specialist (see history) , and got some fairly complimentary feedback. This has gradually been eroded in the meantime, until it's back to the same incomprehensible state of many mathematics pages, unmotivated and completely inaccessible to all but the already expert- those not needing to look it up here in any case. But there seems little point in trying again, as the same thing is likely to happen.

[edit] Speedy deletion of Karl Gass

A tag has been placed on Karl Gass requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about a person or group of people, but it does not indicate how or why the subject is notable: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, articles that do not indicate the subject's importance or significance may be deleted at any time. Please see the guidelines for what is generally accepted as notable, as well as our subject-specific notability guideline for biographies.

If you think that this notice was placed here in error, you may contest the deletion by adding {{hangon}} to the top of the page (just below the existing speedy deletion or "db" tag), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the article meets the criterion it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the article that would would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the article does get deleted, you can contact one of these admins to request that a copy be emailed to you. Triwbe (talk) 12:07, 3 April 2008 (UTC)
