Calculator Description
Elliptical Curves v1
The elliptical calculator including parabolas and hyperbolas

Elliptical Curves

Subject

Elliptical curves describe the path of orbiting objects & trajectories and sections through a cone (conic). See Laws of Motion for a full analysis.

Ellipse: An ellipse is the shape of a curve generated by a straight/flat cut through a single circular cone above its base. It is also the shape of the natural path of an orbiting body (e.g. a planet).

Hyperbola: An hyperbola is the shape of the opposing curves generated by a straight/flat cut through two cones placed tip-to-tip parallel to their axes. It is also the curvature of light around a large gravitational body like a star and the path of subatomic particles repulsed by a nucleus.

Parabola: A parabola is the shape of a curve generated by a straight/flat cut through a single circular cone parallel to its slope. It is also the path of a projectile falling to the ground under the influence of gravity.

Calculator

Ellipses determines the dimensional properties of the three elliptical curves; ellipse, hyperbola and parabola.

In addition to the shape controlling parameters of these curves, the ellipse calculator also determines arc lengths & areas and provides a co-ordinate listing for the curve between 'y=0' and 'y' maximum

For help using this calculator see Technical Help
