This example demonstrates how to calculate the area between two curves using GeoGebra. Key mathematical concepts include integration and functions. Commands such as Intersect, Polygon, Textfield, and Integral are used to construct the area between the curves. Suitable for high school and above students learning area calculation in calculus.

GeoGebra Commands & Parameters

  1. Intersect(f, g) → A, B, C
  2. Polygon((c, g(c)), (c + 0.05, g(c)), (c + 0.05, f(c)), (c, f(c))) → poly1, h, i, j, k
  3. Textfield(lower) → InputBox1
  4. Textfield(upper) → InputBox2
  5. Textfield(f) → InputBox3
  6. Textfield(g) → InputBox4
  7. Integral(p, lower, upper) → rarea
  8. Integral(g) → l
  9. Integral(f) → u
