Question

find the ecentricity of the parabola​

Answer 1

Answer:

To find the eccentricity of an ellipse. This is basically given as e = (1-b2/a2)1/2. Note that if have a given ellipse with the major and minor axes of equal length have an eccentricity of 0 and is therefore a circle. Since a is the length of the semi-major axis, a >= b and therefore 0 <= e < 1 for all the ellipses.
