This example demonstrates how to approximate the area under a curve using Riemann sums. Key mathematical concepts include integration, Riemann sums, and rectangular/trapezoidal areas. Construction involves GeoGebra commands like Textfield, RectangleSum, TrapezoidalSum, LeftSum, and objects such as n, f, a, b, U_n, L_n, c, d, T_n, g, p, M_n, h, t, text4, text1, text2, text3, inputBox1, inputBox2, inputBox3. Suitable for high school students or college freshmen learning calculus basics.

GeoGebra Commands & Parameters

  1. Textfield(a) → inputBox1
  2. Textfield(b) → inputBox2
  3. RectangleSum(f, a, b, n, 1) → U_n
  4. RectangleSum(f, a, b, n, 0) → L_n
  5. TrapezoidalSum(f, a, b, n) → T_n
  6. LeftSum(f, a, b, n) → g
  7. RectangleSum(f, a, b, n, p) → M_n
  8. Textfield(n) → inputBox3
