Abstract
Pell numbers and Pell–Lucas numbers are specific values of Pell polynomials p n (x) and Pell–Lucas polynomials q n (x), respectively. Both families were studied extensively in 1985 by A.F. Horadam of the University of New England, Armidale, Australia, and Bro. J.M. Mahon of the Catholic College of Education, Sydney, Australia [108]. Both families are often defined recursively:
where n ≥ 3. The first ten Pell and Pell–Lucas polynomials are given in Table 14.1.

\((\cos \theta +i\sin \theta )^{n} =\cos n\theta + i\sin n\theta\), where \(i = \sqrt{-1}\) and θ is any angle.
