    5: 14.30 Spherical and Spheroidal Harmonics
    Y l m ( θ , ϕ ) are known as surface harmonics of the first kind: tesseral for | m | < l and sectorial for | m | = l . … P n m ( x ) and Q n m ( x ) ( x > 1 ) are often referred to as the prolate spheroidal harmonics of the first and second kinds, respectively. P n m ( i x ) and Q n m ( i x ) ( x > 0 ) are known as oblate spheroidal harmonics of the first and second kinds, respectively. Segura and Gil (1999) introduced the scaled oblate spheroidal harmonics R n m ( x ) = e i π n / 2 P n m ( i x ) and T n m ( x ) = i e i π n / 2 Q n m ( i x ) which are real when x > 0 and n = 0 , 1 , 2 , . … Most mathematical properties of Y l , m ( θ , ϕ ) can be derived directly from (14.30.1) and the properties of the Ferrers function of the first kind given earlier in this chapter. …
    6: 19.36 Methods of Computation
    F ( ϕ , k ) can be evaluated by using (19.25.5). …A summary for F ( ϕ , k ) is given in Gautschi (1975, §3). … Also, see Todd (1975) for a special case of K ( k ) . For computation of Legendre’s integral of the third kind, see Abramowitz and Stegun (1964, §§17.7 and 17.8, Examples 15, 17, 19, and 20). … For fast methods for computing the incomplete elliptic integral of the first kind see Karp and Sitnik (2007) and Fukushima (2010). …

  • 8: 10.73 Physical Applications
    Bessel functions first appear in the investigation of a physical problem in Daniel Bernoulli’s analysis of the small oscillations of a uniform heavy flexible chain. … Bessel functions of the first kind, J n ( x ) , arise naturally in applications having cylindrical symmetry in which the physics is described either by Laplace’s equation 2 V = 0 , or by the Helmholtz equation ( 2 + k 2 ) ψ = 0 . … Consequently, Bessel functions J n ( x ) , and modified Bessel functions I n ( x ) , are central to the analysis of microwave and optical transmission in waveguides, including coaxial and fiber. See Krivoshlykov (1994, Chapter 2, §2.2.10; Chapter 5, §5.2.2), Kapany and Burke (1972, Chapters 4–6; Chapter 7, §A.1), and Slater (1942, Chapter 4, §§20, 25). … On separation of variables into cylindrical coordinates, the Bessel functions J n ( x ) , and modified Bessel functions I n ( x ) and K n ( x ) , all appear. …
