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

2. Circles
Center: (h, k)
Radius: r

3. 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.

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

5. 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.

6. 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

7. 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.

8. 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

9. Hyperbolas: Underwater Radar
One application of a hyperbola is the LONAR radar system.
This technology is used in submarines. This device detects the intersection of sound waves.
The intersection points create a hyperbola.
