Natural Logarithm Function Demo

This example demonstrates the graph of the natural logarithm function f(x)=ln(x) and its integral properties. Key math concepts include natural logarithm, function graphing, integral calculus, and linear equations. The construction uses GeoGebra commands Segment (line) and Integral (integration), involving objects like function f, variable a, point A, auxiliary function g, point B, constant c, point C, and segment b. Suitable for high school and above, helping students understand logarithmic function characteristics and calculus applications.
