Cosine Function Intersection Demo

This example demonstrates how to graph a cosine function and find its intersections with lines or other shapes using GeoGebra. Key math concepts include cosine function, coordinate geometry, and intersection calculations. The construction uses the Intersect command on objects like list1, f, g, h, A, B, and displays results with text1. Suitable for high school mathematics teaching to understand the geometric meaning and calculation of function graph intersections.
