Question

how to find the eccentricity of parabola​

Answer 1

Answer:

Eccentricity is defined as the ratio of the distance of the moving point P from the fixed point S, to its distance from a fixed line l. Since the two distances are equal in case of a parabola, PS = PM. So, PS/PM = 1. Therefore, we say eccentricity of a parabola is 1.

Answer 2

Answer:

Eccentricity of Parabola

In other words, the distance from the fixed point in a plane bears a constant ratio equal to the distance from the fixed-line in a plane. The general equation of aparabola is written as x2 = 4ay and theeccentricity is given as 1.
