⇒ A lies on the parabola Let S = 2a. Then, AS = AK = a Let us choose A as the origin, AS as the x-axis and AY a perpendicular to A as y-axis. Then the coordinates of S are ( a, 0 ) and the equation of the directrix ZZ’ is x = – a. ...
The major parts of the parabola are the focus, vertex, and the directrix. The parabola comprises equidistant points from the focus (single point of the parabola) and the directrix (line of the parabola). Vertex is a special point where the parabola has a change in its direction, thus ...
