Function Graph Plotter: Multi‑Feature Demo

This example demonstrates a versatile function graph plotter that can dynamically draw various function curves, ellipses, tangents, and other geometric figures. Core mathematical concepts covered include function graphs, trigonometric functions, the Pythagorean theorem, ellipses, variance, and combinatorics. Construction highlights: the applet uses GeoGebra commands such as Textfield and Polygon, and creates objects including c, b, a, xmin, xmax, deltax, ymax, k, Schaltfläche1, f, Textfeld2, Schaltfläche2, Textfeld1, Textfeld3, ymin, Textfeld4, Textfeld5, Schaltfläche3, E1, xmaxhilfe, E3, E4, E2, Vieleck1, e1, e2, e3, e4, Schaltfläche4, Schaltfläche5, kogitter, deltay, xText, xpfeil, XPfeil, Pfeil, Schaltfläche6, Schaltfläche7, g, Textfeld6. It is suitable for high‑school mathematics instruction, college preparatory courses, and self‑study, supporting exploration of function graphs, geometric constructions, and interactive teaching.
