Chebyshev polynomials
Chebyshev polynomials are a sequence of mathematical functions that play a key role in approximation theory, numerical analysis, and computer graphics. They are defined on the interval [-1, 1] and have the unique property of minimizing errors when approximating other functions. Essentially, they help provide the best-fit solutions in various applications, like optimizing data fitting or signal processing. The first few Chebyshev polynomials form a specific pattern and are widely used due to their efficiency and stability in calculations, making them valuable tools in both theoretical and practical mathematics.

Chebyshev Polynomials are a sequence of orthogonal polynomials that arise in mathematics, particularly in approximation theory and numerical analysis. Named after the Russian mathematician Pafnuty Chebyshev, these polynomials help minimize errors when approximating functions. They are defined over the interval [-1, 1] and have important properties, such as exhibiting the least oscillation among polynomials of the same degree. This makes them useful in various applications, including computer graphics, signal processing, and solving differential equations, where controlling precision and errors is crucial.
