La quantità soddisfa la ricorrenza pn=a⋅pn−1 −pn−2 conp0 =2,p1 =a, collegata a polinomi di Chebyshev. Con la formula chiusa Si può dimostrare che pn=2 Tn(a/2) dove Tn è il polinomio di Chebyshev di prima specie. In alternativa, se si pone a=2cosθ),

(quando ∣a∣ ≤2), allora pn=2cos(nθ). Per valori generali di (a) si usano le funzioni iperboliche o direttamente la ricorrenza.

It’s more fun for the continuous case. Let a=x+1/x Then f(x, n)= 2cosh(n acosh(a/2))=2cosh(n acosh((x²+1)/(2x)))
