Talk:Trigonometry/Thales Theorem

Name for Page
I would call this Section "Right triangle trigonometry." -- H Padleckas 20:57, 27 May 2004 (UTC)


 * I agree with the comment that appeared on 27 May 2004. The page should be renamed "Right triangle trigonometry".  That term is conventional in US usage, though I don't know about UK usage.  Douglas W. Mitchell (talk) 15:48, 27 August 2010 (UTC)

Answers for Exercise
What I would like to see are some answers to the questions. Without them there's no way to be certain that you understand correctly. --Rastilin 09:49, 6 Apr 2005 (UTC)

What a Mess
What the heck is going on in this section? There's a lot of stuff in here that is or should be in other pages... --Ilg 17:49, 18 May 2006 (UTC)

Pretty messy a page. Also I want to see math symbols in LaTeX. If no one is gonna change that, I am.--BLY 06:26, 15 June 2006 (UTC)


 * I've started to take things out to new pages JamesCrook (talk) 19:06, 17 October 2010 (UTC)

Im going to at least add some headers so we know what we're dealing with. It looks like some of the proofs in there are useful but should be moved to their appropriate sections (I can start on that after I've labeled everything...) Mattb112885 02:56, 27 August 2006 (UTC)

OK, the headers are added. It looks like whoever wrote the stuff knew what he or she was talking about but did not really look into what the rest of the book was about, it seems to assume some knowledge of calculus, which the author kind of put there out of the blue like, oh by the way you can approximate it with a polynomial... the complex number stuff is quite in-depth, is there a wikibook on complex analysis or something we can put that in? I'm sure we can condense the author's proof to something workable for the target audience. -- Mattb112885 03:19, 27 August 2006 (UTC)


 * I've moved the derivatives of sine and cosine into new pages. Eventually all the material on this page that requires calculus or power series or complex numbers will move into the second chapter of this book. JamesCrook (talk) 18:59, 14 October 2010 (UTC)

"Construction of Right Triangles" - Unclear Directions
If followed, it would seem that the directions in this section would not create a Right Triangle. In fact, it seems like it would create anything but a right triangle. Can someone create an image to demonstrate these directions? 63.65.189.106 (talk) 20:31, 16 September 2010 (UTC)


 * Your correct that these directions are not that great, maybe we should add some different explanations of how to construct a right triangle. In the mean time I will at least point out that they do in fact always produce a right triangle.  This is a consequence of Thales' theorem.  The reason this explanation seems unclear is probably because it is not at all obvious the result will be a right triangle, unless you already knew this theorem.

 * Ah yes, I was wrong. Upon reading the Wikipedia article on the theorem I saw that this would always create a right triangle.  I'm going to add a gif animation from the wikipedia article to add clarification. 63.65.189.106 (talk) 16:30, 17 September 2010 (UTC)


 * Nice work, you should think about making an account and tinkering around for a bit. Thenub314 (talk) 18:19, 17 September 2010 (UTC)


 * Account created. Wasn't originally going to make an account as I wasn't planning on making more then one or two edits.  Now I'm thinking of doing some quality edits as I read through this entire book.Theyain (talk) 20:20, 17 September 2010 (UTC)


 * That is excellent to hear. I am not sure if every page is on my watchlist, so if you have a question and no one is responsive to the talk page right away you can always drop a note at the mathematics project discussion page.  Thenub314 (talk) 21:04, 17 September 2010 (UTC)


 * Its going to be a while (a week at most) before I can start again as my classes have changed again. This means constant access to the Online world is limited once again.  -_- Theyain (talk) 21:54, 22 September 2010 (UTC)
