A new derivation of a closed form expression for Chebyshev polynomials of any order

The author presents a new derivation of a closed-form expression for the Chebyshev polynomial C/sub n/( omega ) based on the method of the Z-transform. The result permits the rapid determination of C/sub n/( omega ) for any order n without the need to evaluate C/sub n/( omega ) for all lower values of n.<
