Document Summary
When the focus is at the origin and vertex lie along a vertical line, then is used. When the equation of the directrix lies below the -axis, then use , and it if it is above the -axis, With the focus at the origin and the vertex lying on a horizontal line, then is used. When the equation of the directrix is to the right side of the -axis, then use , and it if it is to the left of. Write a polar equation of a conic with the focus at the origin and the given data. And the sign is negligent because represents only the distance from the focus at the origin. Then the directrix line is a vertical to the left to the focus at the origin.
