Conic Applications in the Real World
A sample presentation by Mrs. Kohler

Circles Center: (h, k) Radius: r

Circles: A Roulette Table
One application of a circle is a Roulette Table. The spinning of the wheel keeps the ball on the rim. Slower spinning lessens the centrifugal force and the ball drops in a slot.

Ellipses Center: (h, k) Foci Formula: (where a > b)

Ellipses: The Solar System
One application of the ellipse is the orbits of the planets in our solar system. The sun represents one of the foci.

Parabolas Vertical Parabolas Vertex: (h, k) Horizontal Parabolas
Focus: (h, k+c) Directrix: y = k – c Horizontal Parabolas Vertex: (h, k) Focus: (h+c, k) Directrix: x = k – c

Parabolas: A Light Filament
One application of a parabola is the filament in a flashlight. The mirrors on the filament cause the reflection of the bulb to shine outward.

Hyperbola Horizontal Hyperbola Vertex: (h, k) Foci: (h+c, k) (h–c, k)
Vertical Hyperbola Vertex: (h, k) Foci: (h, k +c) (h, k–c) Foci Formula
