Show that polar eqn of conic section is r = ep/1-e sin(@)

[jbrosrulez]

Let F, the focus of a conic section, be the origin, and let d, the directrix, be the line y = -p, where p>0. Let P be a point in the xy-plane and let PD be the perpendicular distance from P to d.

Consider the set of points is a conic section, and the number e is the eccentricity of the conic section. Use this definition of a conic section to show that the polar equation of the conic section is: r= ep/ 1- e times sin theta. Then find three more polar equations for the conics having directrices y=p, x=-p, and x=p

MUCH HELP NEEDED
