Tangent Line and Derivative Demo

This example demonstrates how to draw the tangent line of a function and show its relationship with the derivative. Core math concepts include derivatives, tangent lines, difference and slope, and differential calculus. Construction highlights involve using GeoGebra commands/objects like Circle, Line, OrthogonalLine, and Intersect. Suitable for high school and above students learning calculus to visually understand the geometric meaning of derivatives.
