Some identities involving Chebyshev polynomials, Fibonacci polynomials and their derivatives
NOTES ON NUMBER THEORY AND DISCRETE MATHEMATICS(2023)
摘要
In this paper, we will derive the explicit formulae for Chebyshev polynomials of the third and fourth kind with odd and even indices using the combinatorial method. Similar results are also deduced for their rth derivatives. Finally, some identities involving Chebyshev polynomials of the third and fourth kind with even and odd indices and Fibonacci polynomials with negative indices are obtained.
