Tangent Line to a Curve

This example demonstrates how to draw tangent lines to a curve. It involves core mathematical concepts such as derivatives, coordinate geometry, and geometric construction. Construction highlights include using GeoGebra commands like Derivative (for finding derivatives), IntersectPath (for intersecting paths), Line (for drawing lines), Textfield (for text input), and Segment (for segments), along with objects like P (point), f (function), a (parameter), A (point), f_x (derivative x), f_y (derivative y), d (point), e (point), c (point), pt (point), u (point), g (object), CampEntradaSortida1 (input/output 1), CampEntradaSortida2 (input/output 2), h (object), and text1 (text). Suitable for high school students learning calculus and coordinate geometry.
