Eccentricity of polar equation
http://www.opentextbookstore.com/precalc/2/Precalc9-4.pdf WebThis constant ratio is the eccentricity e of the conic. e tells us which kind of conic it is. If 0 < e < 1, the conic is an ellipse. If e = 1, the conic is a parabola. If e > 1, the conic is a hyperbola. In a polar equation for a conic, the pole is the focus of the conic, and the polar axis lies along the positive x -axis, as is conventional.
