EQUATION OF A PARABOLA GIVEN FOCUS AND DIRECTRIX

What is a parabola? How is it derived from conics? Watch this presentation to find out. Here, we learn how a parabola is derived when a plane cuts a cone. We learn that, for a parabola, distance of a point from the focus = distance of the point from the directrix. We solve problems based on this principle and also learn how to calculate equation of the axis and the coordinates of the vertex. This is useful for grade 11 maths students.
