Question

How does the numerical value of the eccentricity, "e", change as the shape of an ellipse approaches a straight line?

Answer 1

At eccentricity = 0 we get a circle For 0 < eccentricity < 1 we get an ellipse for eccentricity = 1 we get a parabola for eccentricity > 1 we get a hyperbola for infinite eccentricity we get a line
