Conic Sections
A conic section is a curve that is generated by the intersection of a plane and a curved surface. The most common conic sections are circles, parabolas, and ellipses.
Circles are formed when a plane intersects a circle at one point. The line of intersection is called the diameter. The radius of the circle is half the distance from the center to the edge.
Parabolas are formed when a plane intersects a parabola at two points. The point of intersection is called the vertex. The distance from the vertex to the center is equal to the radius of the parabola.
Ellipses are formed when a plane intersects an ellipse at two points. The line of intersection is called the major axis. The center of the ellipse is located at the midpoint between the vertices. The major axis is parallel to the major axis of a circle.
Conic sections are important in engineering, architecture, and other fields because they can be used to model real-world objects and systems. For example, bridges, arches, and lenses are all examples of conic sections
