Conic Sections
Conic sections, often called conics, are the family of curves produced when a flat plane slices through a double cone — two identical cones positioned with their tips touching. Depending on the angle and position at which the plane cuts the double cone, one of four distinct curves results: a circle (plane perpendicular to the cone's axis), a parabola (plane parallel to the slant of the cone), an ellipse (plane at an angle that cuts completely through one nappe), or a hyperbola (plane parallel to the axis, cutting through both nappes). These curves appear throughout everyday life — in cell-phone signals, acoustics, satellite dishes, and navigation systems — making them foundational shapes in algebra and geometry.
