This example demonstrates how to identify the derivative of ln x as 1/x by plotting tangents and calculating their slopes at different points along the function. Core math concepts include derivatives, tangent function, and slope. Construction highlights involve using commands like Point, Tangent, and Slope, along with objects f, A, a, m, text1, text2. Suitable for high school students learning calculus.

GeoGebra Commands & Parameters

  1. Point(f) → A
  2. Tangent(A, f) → a
  3. Slope(a) → m

AI Drawing Prompt Reference

Draw the graph of the natural logarithm function, select a point on the curve, draw a tangent line from this point, calculate and display the slope of the tangent line to verify that it equals the derivative of the function at that point, which is 1/x.
