Tangent Slope on a Parabola

This example demonstrates the calculation and visualization of the slope of a tangent line on a parabola at any point. Key math concepts include parabola equation, tangent slope, and the geometric meaning of derivatives. GeoGebra commands used are Tangent for drawing the tangent line, Slope for calculating the slope, and objects like f (function), a (parameter), A (point), c (constant), Slope (text displaying slope value), and text1 (text object). Suitable for high school students learning analytical geometry and introductory calculus.
