Dynamic Visualization of the Fundamental Theorem of Calculus

This GeoGebra example demonstrates the Fundamental Theorem of Calculus by dynamically adjusting the integration interval and showing how the accumulated area equals the antiderivative value. Core concepts include integrals, derivatives, tangents, area accumulation, and linear functions. Construction relies on Point for A/B, Integral for int, Tangent for derivatives, Polygon/Segment for shaded regions, and Intersect/Midpoint for key locations. Suitable for high-school advanced and undergraduate calculus learners.
