Notes On Conic Sections

The three types are parabolas ellipses and hyperbolas.

Notes on conic sections. There is no center in parabola. This form of the equation is helpful since you can easily find the center and the radius. The center radius form of the circle equation is in the format x h 2 y k 2 r2 with the center being at the point h k and the radius is r.

A conic section can be graphed on a coordinate plane.

The equation of a circle with radius r having centre h k is given by x h 2 y k 2 r 2. The general equation for a conic section is 0ax2 by2 cxy dx ey f. Vertex the right circular cone consists of two cones joint at a fixed point is called vertex represented as v in the above picture.

A conic section or simply conic is a curve obtained as the intersection of the surface of a cone with a plane. Center the point at the center of a circle an ellipse or a hyperbola.
