Derivative as Limit of Secant Slopes
Loading the math board and drawing, please wait…
This example demonstrates how the derivative at a point on a function is defined as the limit of the slopes of secant lines. Key math concepts include derivative, secant line, slope, and limit. It is constructed using GeoGebra commands/objects like Point, Line, Slope, and Segment. Suitable for high school and above students learning calculus to visually understand the geometric meaning of derivatives.

AI Drawing Prompt Reference
Draw a horizontal axis and mark two points on it. Connect one of these points to a point on a function's graph to form a secant line, then calculate the slope of this line. Next, draw the line segment connecting the two points on the axis. Finally, show the trend of the secant slope as the two points approach each other, illustrating the geometric meaning of the derivative.
