PF = P to directrix
Read Instructions
Keywords : PF = P to directrix is parabola
Defintion
  • PF = Point P to focus F.
  • PQ = Point P to directirx.
  • PF = PQ then locus of P is a parabola.
  • Equation of parabola is y + D/2 = x^2/(2*D).
  • Where D is the distance from focus F to the directrix.
