This example demonstrates the geometric meaning of derivatives, showing the slope of a tangent line at a point on a function. Core math concepts include derivatives, slopes, vectors, and distances. It uses GeoGebra commands like Textfield, Point, Intersect, Slope, Segment, Dilate, Vector, Distance, Circle. Suitable for high school students learning calculus to visually understand derivative concepts.
