The kth Degree Chebyshev Polynomial

This example demonstrates the graph of the kth degree Chebyshev polynomial. Chebyshev polynomials are a class of important polynomial functions widely used in approximation theory and numerical analysis. Through GeoGebra, we can visually observe the changes in the polynomial's graph and understand its properties. This example uses the Text command to display the coefficients and key points of the polynomial, suitable for high school mathematics education and learning.
