This example demonstrates the concept of the first derivative. By drawing a function and its tangent, it visually illustrates the relationship between the derivative and the slope of the function. Commands used include FitPoly, If, Point, Tangent, Slope, and Segment. Suitable for high school math education, aiding students in understanding the basic concept of derivatives.

GeoGebra Commands & Parameters

  1. FitPoly({A1, B1, C1, D1}, 3) → f2
  2. If(d ≟ 1, f3, If[d ≟ 2, f2, f1]) → f
  3. Point(f) → A
  4. Tangent(A, f) → a
  5. Slope(a) → m
  6. Segment(B, C) → b
  7. Segment(D, E) → c
  8. Corner(1, 1) → P
  9. Corner(1, 2) → Q
  10. Derivative(f) → g

AI Drawing Prompt Reference

Draw a cubic polynomial function curve in a coordinate plane. Place a movable point on the curve, and construct the tangent line to the curve at that point, displaying its slope value. Also, draw two fixed segments to indicate an interval, and plot the derivative curve of the function below or alongside. The overall figure illustrates how the derivative corresponds to the slope of the tangent line.
