VectorCoordinate GeometryParametric Equation
This example demonstrates the geometric properties and definitions of focal conics (ellipses and hyperbolas). Key math concepts include conic sections, foci, eccentricity, parametric equations, vectors, and analytical geometry. Construction involves commands like Point and Intersect. Suitable for high school and above to understand the geometric essence and parametric representation of conic sections.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Point(yAxis) → C
  3. Intersect(xAxis, c) → D, E

AI Drawing Prompt Reference

Draw a coordinate system with x and y axes, mark their intersection point, take a point on the x-axis and a point on the y-axis, then find the intersection points of the x-axis with c, and use these points to construct the figure, demonstrating the focal properties of ellipses and hyperbolas.
The prompt above was compiled from the original drawing commands and is for reference only.
