Derivative (Tangent Line Compared to f'(a))

This example illustrates the concept of derivatives by comparing the tangent line of a function f at point a with the derivative value f'(a). By adjusting the position of point a, you can observe the consistency between the slope of the tangent line and the derivative value. The Derivative command in GeoGebra is used to calculate the derivative, and points A and B are used to demonstrate the tangent line and the derivative value. Suitable for high school mathematics education and learning calculus concepts.
