Graphical Derivative Calculation

This example demonstrates the calculation of a function's derivative at a point using graphical methods. Key math concepts include the geometric interpretation of derivatives (tangent slope) and coordinate geometry. Construction highlights the use of GeoGebra commands and objects like Point, Tangent, Slope, Locus, and Textfield to dynamically visualize the change in tangent and slope, intuitively illustrating the concept of derivatives. Suitable for high school and above students learning basic calculus concepts.
