Fixed line of parabola
WebParabola is a set of all points in a plane that are equidistant from a fixed point and a fixed line. The fixed point is called the focus, and the fixed line is called directrix.The turning point is called vertex which is equidistant from the focus and the directrix FOCUS – is the fixed point that is used to define the parabola with the fixed line. VERTEX – is the … WebApr 6, 2024 · In other words, we can say that the distance from the fixed point in a plane bears a constant ratio equal to the distance from the fixed line in a plane. Therefore, the Eccentricity of the Parabola is always equal to 1 ( e=1) The general equation of a Parabola can be written as x2 = 4ay and the Eccentricity is always given as 1.
