Chebyshev Polynomials - Definition and Properties. The Chebyshev polynomials are a sequence of orthogonal polynomials that are related to De Moivre's formula. They have numerous properties, which make them useful in areas like solving polynomials and approximating functions.

This is a recursive equation for the Chebyshev polynomial, meaning we can get the next polynomial from the current one and the previous one. All we need is to know T 0 ( x ) = 1 and T 1 ( x ) = x .
