This example demonstrates how to calculate the area under a curve using GeoGebra, involving core concepts like integration, functions, polygons, and vectors. It utilizes commands such as Intersect, Point, Polygon, PointIn, and Segment for construction, making it suitable for high school and above students learning calculus applications.

GeoGebra Commands & Parameters

  1. Intersect(f, yAxis, 1) → A
  2. Point(f) → B
  3. Point(xAxis) → C
  4. Intersect(xAxis, yAxis) → D
  5. Polygon(A, B, C, D) → q1, a, b, c, d
  6. Point(f) → E
  7. Point(xAxis) → F
  8. Polygon(B, E, F, C) → q2, b_1, e, f_1, c_1
  9. Intersect(f, xAxis, 2) → G
  10. Polygon(E, G, F) → t1, f_2, e_1, g
  11. PointIn(q1) → Pointq1
  12. PointIn(q2) → Pointq2
  13. PointIn(t1) → Pointt1
  14. Segment(D, F) → i
  15. Segment(G, D) → j
  16. Polygon(A, B, E, G, D) → poly1, a_1, b_2, e_2, g_1, d_1
  17. PointIn(poly1) → Pointpoly1
