Eccentricity of a parabola should be

WebEccentricity of Conics. To each conic section (ellipse, parabola, hyperbola) there is a number called the eccentricity that uniquely characterizes the shape of the curve. A circle has eccentricity 0, an ellipse between 0 and 1, a parabola 1, and hyperbolae have eccentricity greater than 1. Although you might think that y=2x 2 and y=x 2 have ... WebThe eccentricity of a parabola is always 1. Directrix. Directrix is the line drawn parallel to the axis at a distance. Solved Examples Example 1. Consider the following equation: \[ x^2-3y+6=0 \] Determine the focal diameter, directrix, eccentricity, and vertex of the above parabolic equation.
