In Maxime B�cher's 1891 dissertation, " Ueber die Reihenentwickelungen der Potentialtheorie ", it was shown that the Laplace equation in three variables can be solved using separation of variables in 17 conformally distinct quadric and cyclidic coordinate geometries.

While neither Apollonius nor any other Greek mathematicians made the leap to coordinate geometry, Apollonius'treatment of curves is in some ways similar to the modern treatment, and some of his work seems to anticipate the development of analytical geometry by Descartes some 1800 years later.

Specifically, I went to : category : Coordinate geometry and clicked on " edit " and then on " what links here " and found nothing, although there was an article that bore that category tag . ( The article was law of tangents, from which I removed the tag because it doesn't fit even if there were such a category . ) talk ) 23 : 45, 9 December 2008 ( UTC)

Already Ren?Descartes in his " Discourse on the Method " had attested to the impact Renaissance planned new towns had upon his own thought, and much evidence exists that the Renaissance streetscape was also the perceptual stimulus that had led to the development of coordinate geometry ( see, e . g ., Claudia Lacour Brodsky, " Lines of Thought : Discourse, Architectonics, and the Origins of Modern Philosophy ", Duke 1996 ).
