WebA parabola is the locus of a point that is equidistant from a fixed point called the focus (F), and the fixed-line is called the Directrix (x + a = 0). Let us consider a point P(x, y) on the parabola, and using the formula PF = PM, we can find the equation of the parabola. WebThe fixed line is known as Directrix. A chord passing through the focus is known as focal chord. The straight line through focus and perpendicular to directrix is known as Axis. …
