Introduction to Differential Calculus

This example demonstrates the concept of derivatives in differential calculus by visualizing the tangent line and slope at a point on a function. The core math concepts involved include derivatives, tangent lines, slopes, and function graphs. It uses GeoGebra commands and objects like Point, Tangent, and Slope to construct the tangent point and line, dynamically showing the slope variation. Suitable for high school and above students learning differential calculus to intuitively understand the geometric meaning of derivatives.
