Fixed line of parabola
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 the ‘directrix’ and the fixed point is the ‘focus’ {Fig. 1 (a)}. In simple words, it is the shape described when we throw a ball in the air. Further, a line through the focus …
