Tangent-zoom

This example demonstrates how to draw the tangent line at a point on a function graph and observe the relationship between the tangent line and the function graph through zooming. Core mathematical concepts include functions, derivatives, tangent equations, and coordinate geometry. Construction highlights involve using GeoGebra commands and objects such as Point, Tangent, LaTeX, Polygon, f (function), P (point), tangent (tangent object), tekst1 (text), zoom (zooming), B, A, D, C, zoomvindue (zoom window), a, d, c, b (parameters). Suitable for high school mathematics teaching to help students understand the geometric meaning of derivatives and properties of tangents.
