This example demonstrates how to use definite integrals to calculate the area under a function. Key mathematical concepts include definite integrals and functions. Using GeoGebra commands such as Integral, Dilate, and Intersect, the construction of the definite integral graph is achieved. Suitable for high school and above students learning calculus.

GeoGebra Commands & Parameters

  1. Integral(f, a, b) → d
  2. Integral(f, a, c) → e
  3. Dilate(B, If[0 < j ≤ 1, 1 - j, 0], C) → B'
  4. Integral(f, x(B), x(B')) → k
  5. Dilate(C, If[1 < j ≤ 2, 2 - j, 0], A) → C'
  6. Integral(f, x(C), x(C')) → l
  7. Intersect(f, g) → D
  8. Segment(B, D) → m
  9. Segment(C', E) → n
  10. Segment(C, F) → p
  11. Intersect(f, h) → G
  12. Segment(A, G) → q
  13. Textfield(f) → InputBox1
  14. Textfield(a) → InputBox2
  15. Textfield(b) → InputBox3
