Conic section (polar system and one focus on the pole and the other somewhere on the 0° ray )
Description
conic section (or just conic) is a curve obtained as the intersection of a cone (more precisely, a right circular conical surface) with a plane. A conic section with one focus on the pole and the other somewhere on the 0° ray (so that the conic’s major axis lies along the polar axis) is given by a polar equation.
