Introducing Limit Notation

This example demonstrates how to incorporate and visualize limit notation in GeoGebra, dynamically showing the process of function values approaching a specific point. Core math concepts include limits, function continuity, and sequence convergence. Construction highlights the use of GeoGebra's Limit command, Graphics command for function plotting, and Slider command to dynamically adjust the independent variable and observe changes in the limit value. Suitable for high school calculus入门 teaching to help students intuitively understand the concept of limits.
