This example demonstrates the symmetry in the integral of functions f(x) and f(a-x). It involves core math concepts like integration, function symmetry, and calculus. The construction uses GeoGebra commands/objects: Point, Integral, LaTeX, and Textfield. Suitable for high school and above students learning calculus and function properties, ideal for teaching demonstrations and concept understanding.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Integral(f, 0, x(A)) → a
  3. Integral(g, 0, x(A)) → b
  4. LaTeX(f, true, true) → text1
  5. LaTeX(g, true, true) → text2
  6. Textfield(f) → InputBox1

AI Drawing Prompt Reference

Draw a coordinate plane with a movable point on the x-axis. Define two functions f and g, where g is the mirror of f about the vertical line x = a/2 (i.e., g(x) = f(a-x)). Plot both curves in distinct colors, and shade the integral areas from 0 to the point's x-coordinate for each function with semi-transparent fills. Display the symbolic expressions of f and g as LaTeX-style text near the curves, and include an input box to edit f's expression, causing the graph to update dynamically. Emphasize the symmetry of the two shaded integral regions about the central vertical axis.
