real world applications of conic section ( parabolas, hyperbolas, ellipses, and circles )


 We all always ask ourselves after a math class if its going to be used in real life or have any impact on us as humans. Here is one example of such question & the answer from one of our middle school Math class.

I of IiI:  real world applications:

We all know that a conic section is the intersection of a "plane" and a "double right circular cone". By changing the angle and location of intersection we can produce a circle, ellipse, parabola or hyperbola ( or in the special case when the plane touches the vertex: a point, line or 2 intersecting lines. parabola, 2 parallel lines, 1 line or no curve). Lets look at some real world applications of parabolas, hyperbolas, ellipses, and circles.
