This example illustrates the concepts of inverse functions and derivatives. By plotting a function and its inverse, and using the derivative definition to find tangents, students can visually understand the geometric meaning of derivatives. The construction summary mentions the use of CurveCartesian, Tangent, Segment, and other GeoGebra commands. Suitable for high school mathematics, particularly calculus courses.

GeoGebra Commands & Parameters

  1. CurveCartesian(ℯ^(t) + (0.5 * t^(3)), t, t, -10, 10) → b
  2. Tangent(A, f) → c
  3. Tangent(B, b) → d
  4. Segment(A, B) → e
  5. Point(f) → C
  6. OrthogonalLine(C, a) → g
  7. Intersect(g, b) → D, D_1
  8. Segment(C, D) → h
  9. Tangent(D, b) → i
  10. Tangent(C, f) → j

AI Drawing Prompt Reference

Draw the graph of the function y=e^x and find its tangent at x=0. Then, draw the inverse function and find its tangent at y=1. Connect the point (0,1) on the original function's graph with the point (1,0) on the inverse function's graph, and draw the perpendicular bisector of these two points. Finally, draw the tangent line through the intersection point that is tangent to the original function's graph.
