Derivative as Tangent Slope Function

This example demonstrates how to dynamically construct to show that the derivative of a function at a point is the slope of the tangent line at that point. It involves core math concepts: derivative, tangent slope, function graph, dynamic geometry. Construction highlights include using commands like Point, Tangent, Segment, Textfield to create the function f graph, points A and B, tangent line, and line segments with text annotations. Suitable for high school mathematics teaching, ideal for students learning calculus to visually understand the geometric meaning of derivatives.
