Talk:Conic Sections

What do people think of deleting circles and integrating it with ellipses, since technically the two are the same thing? Also I have started trying to make some big additions to this wikibook, but this is the first time I have ever contributed so please tell me if I do anything wrong. Lakshan 12:45, 25th February 2011

I've moved all 5 pages to WB:NP friendly names... --Azertus 23:00, 13 August 2005 (UTC)

Illustrations needed
At a minimum, I suggest two illustrations for each conic, one showing the plane intersecting with the cone to form the conic, and another showing the conic straight on, with characteristic points (center, foci, vertex) and lines (axes, directrix, asymptotes) of the conic section denoted.

Revamping
I hate to be so assertive, but here's what I plan on doing in terms of structure:

Conic Sections Introduction: Just what it says. Connections to Flatland.

Types of Conic Sections General Conic Sections: Two equation formats (Ax^2+Bxy+Cy^2+Dx+Ey+F=0 and (x-h)^2/A+y^2/B=1) The Circle The Ellipse The Parabola The Hyperbola Lines and Points: Unofficial Conic Sections: just to mention it.

Features of Conic Sections Foci of Conic Sections: The foci, directrix, and defining conic sections in terms of that. Conic Sections as Loci: defining conic sections as loci. No axes involved. Eccentricity: Stuff about eccentricity. Identifying conic sections by eccentricity.

Conic Sections as Algebraic Relations Intercepts of Conic Sections: finding x and y intercepts. How this can help graphing Translation of Axes: how the take the ABCDEF format and transpose the x and y axes Rotation of Axes: derivation of most things worth knowing about rotation Rotation of Axes (examples): examples on a seperate page Slopes of Conic Sections: Calculus stuff. Implicit derivation

Concluding Remarks: applications of conic sections (parabolas as paths of objects under gravity, for example) Acknowledgements and Further Reading: Just that. Some sources contributors have found helpful.

Just leave it be for a while. I'll at least establish the structure, and then some. Grace notes  T &#167; 02:48, 22 June 2006 (UTC)


 * Once again, would you be so kind as to not touch anything! Thank you. I'd just like to get off on the right foot. Including me, there have only been 10 edits in the past year. The next one is technically not due until about 2 weeks.Grace notes  T &#167; 02:53, 22 June 2006 (UTC)


 * This is a wiki. If you ask nicely, I'll leave it alone for a week or two, but eventually this will be "edited mercilessly", etc. How can I help make it better? --DavidCary 20:01, 18 October 2007 (UTC)
