Focus conics
WebThe first mention of "foci" was in the multivolume work Conics by the Greek mathematician Apollonius, who lived from c. 262 - 190 BCE. One theory is that the Ancient Greeks began studying these shapes - ellipses, parabolas, hyperbolas - as they were using sundials to study the sun's apparent movement. ...
