The Derivative by Anne Bjørnestad

This example illustrates the concept of a derivative, which is the instantaneous rate of change of a function at a given point, a core concept in calculus. By dragging point A, you can observe how the slope of the tangent line to the function f changes at different points. The example uses the Function command to define the function and points A, B, C, etc., to represent points on the function's graph. Suitable for high school mathematics education and learning about derivatives.
