Question

How can the equation of a parabola be derived when given the focus and the directrix

Answer 1

If the focus of a parabola is and the directrix is , find theequation of the parabola. Let ( x 0 , y 0 ) be any point on theparabola. Find the distance between ( x 0 , y 0 ) and the focus. Then find the distance between ( x 0 , y 0 ) and directrix.
