Riemann Sums Demonstration

This example demonstrates the geometric interpretation of definite integrals through Riemann sums, visualizing the approximation process of upper sums, lower sums, and trapezoidal sums. Key math concepts include definite integrals, Riemann sums, upper and lower sums, trapezoidal sums, and function graphs. Constructed using GeoGebra commands like Point, UpperSum, LowerSum, TrapezoidalSum, Integral, and objects such as f (function), text1-5 (texts), A and B (interval endpoints), n (partition number), u and l (variables), t (temporary object), and a and b (parameters). Suitable for high school and above students learning calculus to intuitively understand the definition and computation of definite integrals.
