Polar Coordinates
In polar coordinates, a conic section with one focus at the origin and, if any, the other on the x-axis, is given by the equation
where e is the eccentricity and l is the semi-latus rectum (see above). As above, for e = 0, we have a circle, for 0 < e < 1 we obtain an ellipse, for e = 1 a parabola, and for e > 1 a hyperbola.
