This example demonstrates how to graph an ellipse using GeoGebra. Key mathematical concepts include the definition and properties of an ellipse. Commands such as `If`, `Focus`, `Polygon`, and `RotateText` are used to construct the ellipse. Suitable for high school mathematics education and learning about ellipses.

GeoGebra Commands & Parameters

  1. If(a > b, (h, b + k), (a + h, k)) → V_3
  2. Focus(p) → F_1, F_2
  3. Polygon((h, k), F_2, V_3) → poly1, d, e, g
  4. RotateText(text7, 1.5708) → text2
  5. CurveCartesian((a * cos(t)) + h, (b * sin(t)) + k, t, 0, k_1) → f
  6. If(a > b, ((-a) + h, k), (h, (-b) + k)) → V_1
  7. If(a > b, (a + h, k), (h, b + k)) → V_2
  8. If(a > b, (h, (-b) + k), ((-a) + h, k)) → V_4
  9. Segment((h, k - (i * b)), (h, k + (i * b))) → a_1
  10. Segment((((-j) * a) + h, k), ((j * a) + h, k)) → b_1
  11. Angle(F_2, (h, k), V_3) → α

AI Drawing Prompt Reference

Draw an ellipse, showing its foci and definition. Start by plotting the center and major/minor axes, then connect the foci to points on the ellipse to form auxiliary shapes. Next, use a parametric equation to plot the ellipse curve, labeling the foci and center. Finally, add text annotations to explain the definition and properties of the ellipse for clarity.
