Tangent Line to a Curve (Quotient Rule)

This example demonstrates how to draw the tangent line to a function curve at a specific point using GeoGebra, illustrating the relationship between the slope of the tangent line and the derivative of the function. Core mathematical concepts include functions, derivatives, tangent line equations, and the quotient rule. GeoGebra commands/objects used are Point, Tangent, f, f', P, Q, L, m, and text1. Suitable for university calculus courses or math enthusiasts studying the geometric meaning of function graphs and derivatives.
