aravindg · Answer

The Greeks discovered the properties that define conics in terms of points and lines. These properties are important tool for current day problems with the behaviors of atoms, molecules and outer space. Particles that move under the influence of an inverse square force field has a path that is described by conic sections.

$$\large CIRCLE$$Each of the geometric figures are obtained by intersecting a double-napped right circular cone with a plane. Thus, the figures are called conic sections or conics. If the plane cuts completely across one nappe of the cone and is perpendicular to the axis of the cone, the curve of the section is called a circle.

$$\large Ellipse$$ If the plane isn't perpendicular to the axis of the cone, it is called an ellipse.

An ellipse is the set of all points in a plane, the sum of the distances from two fixed points in the plane is constant.

Many comets have elliptical orbits.

$$\large Parabola$$ 
If the plane doesn't cut across one entire nappe or intersect both nappes, the curve of the intersection is called a parabola.

A parabola is the set of all points in a plane equidistant from a fixed point and a fixed line in the plane.

aravindg · Answer

$$\large Hyperbola$$ 
If the plane cuts through both nappes of the cone, the curve is called a hyperbola.

The hyperbola is the set of all points in a plane. The difference of whose distance from two fixed points in the plane is the positive constant.

thanks

apoorvk · Answer

Great work :P

some diagrams depicting conics could have been the icing, whaddya think? ;)

experimentx · Answer

many nice tutorials are coming
I think we should create a community wiki composed of tutorials ...
