Tangent Line to a Parametric Curve

This example demonstrates how to draw the tangent line to a parametric curve at a specific point. Key math concepts include parametric equations, derivatives, and tangent line equations. GeoGebra commands used are CurveCartesian for plotting the curve, and objects like t, P, f, g, a, m, h represent parameters, points, functions, and ranges, with text1 for annotations. Suitable for high school and above students learning applications of parametric equations and derivatives, or for calculus instruction.
