Function Derivative Demo

This example dynamically demonstrates the function and its derivative, visually showing the rate of change of the function and the geometric meaning of the derivative. It involves core math concepts like function, derivative, plane geometry, trapezoid, isosceles triangle, upper and lower sums or Riemann sums. Construction highlights include GeoGebra commands/objects: object f for the function, object f' for the derivative. Suitable for high school and above learning calculus and analytical geometry to understand the definition and geometric application of derivatives.
