did the system also have conic sections?
UNANSWERABLE
when are polar coordinates used in real life They are used often in navigation as the destination or direction of travel can be given as an angle and distance from the object being considered what is this system about? A two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction who was the first to come up with this system? Grégoire de Saint-Vincent and Bonaventura Cavalieri independently introduced the concepts in the mid-seventeenth century, though the actual term "polar coordinates" has been attributed to Gregorio Fontana who was the first person? A Flemish Jesuit and mathematician best remembered for his work on quadrature of the hyperbola and who was the second? An Italian mathematician and a Jesuate has he also worked in astronomy? Yes. Towards the end of his life, Cavalieri published two books on astronomy

Polar coordinate system [SEP] Conic sections
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: where "e" is the eccentricity and formula_15 is the semi-latus rectum (the perpendicular distance at a focus from the major axis to the curve). If , this equation defines a hyperbola; if , it defines a parabola; and if , it defines an ellipse. The special case of the latter results in a circle of the radius formula_15.
