Geometric Interpretation of Riemann Sum

This example uses geometric figures to demonstrate the concept of Riemann sum, aiming to validate the applicability of geometric constructions in known equations. It involves core mathematical concepts such as functions, integrals, and limits. Using GeoGebra commands like Segment, Textfield, and Polygon, it constructs a geometric model of the Riemann sum. Suitable for calculus education, helping students visually understand the calculation method of Riemann sum.
