The parametric forms are:

Circle: (r cos θ, r sin θ),

Ellipse: (a cos θ, b sin θ),

Parabola: (at^2, 2at),

Hyperbola: (a sec θ, b tan θ) or (±a cosh u, b sinh u),

What a conic section?

A conic section is a curve formed by the intersection of a plane with a cone (conical surface). If the section is parallel to the base of the cone, the conic section has a fixed diameter and is a circle. Any other plane that does not intersect the apex is either a parabola, a hyperbola, or an ellipse.
