We invoke that an ellipse is the locus of a point which moves such that its distance from a fixed point (focus) bears a constant ratio (eccentricity) less than unity its distance from its directrix bearing a constant ratio e ( < < e (i) Equation of an Ellipse in standard form Let S be a focus, l be a directrix, e be the eccentricity ( < < e ) and P x y ( , ) be the moving point. Draw SZ and PM perpendicular to l .
