Second Derivative Example by Jan Mays

This example demonstrates the geometric and physical significance of the second derivative, showing concavity and inflection points through dynamic graphs. It involves core math concepts like derivatives, function graphs, concavity, inflection points, and inequalities. Constructed using GeoGebra commands such as Derivative and Textfield, with objects e, f, g, h, and InputBox1 for interactive input and dynamic visualization. Suitable for high school and above students learning calculus to understand function properties and derivative applications.
