Exploring the Gradient of a Function

This example demonstrates how to dynamically visualize the tangent line and its slope at a point on a function using GeoGebra. Core mathematical concepts include functions, derivatives, tangent slope, and analytical geometry. Key GeoGebra commands/objects used are Tangent, Slope, x_1, f, A, g, m, B, and a, which help illustrate the geometric meaning of derivatives and tangent line calculations. Suitable for high school calculus instruction.
