This example demonstrates the origin of the derivative definition by dynamically showing how the slope of a tangent line changes at a point on a function. It involves core math concepts like derivatives, limits, exponentiation, linear regression, scatter plots, histograms, and continuity. The construction uses GeoGebra commands: Function, Point, Line, Segment, Tangent, and objects: f, A, B, a, C, b, c, D, E, F, G, text1, d. Suitable for high school and above students to understand the geometric meaning of derivatives and the concept of limits.

GeoGebra Commands & Parameters

  1. Function((1 / 5 * x^(2)), -5, 5) → f
  2. Point(f) → A
  3. Point(f) → B
  4. Line(A, B) → a
  5. Segment(B, C) → b
  6. Segment(A, C) → c
  7. Tangent(A, f) → d

AI Drawing Prompt Reference

Draw a function graph and select two points on it to form a line. Then, draw a tangent line at one of the points. Extend the line from the tangent point to create a new point, and connect these two points. Label the function graph, tangent line, and the extended line to demonstrate how the slope of the tangent line changes as the point moves, illustrating the concept of derivatives and limits.
