Talk:Parabola

When I tried to insert math tags around the equation, it "failed to parse." Help appreciated. Also, this is definitely incomplete. I plan to add more when I get back tonight. --Mysmartmouth 11:07, 18 June 2006 (EDT)

Separate articles for focus & directrix?

Do we really need separate articles for the focus and directrix of a parabola? I think we could give them a better coverage here instead of making a whole new article on them. --1=2 14:46, 22 March 2012 (EDT)
