    A sentence and unnumbered equation

    R C ( γ δ , γ ) = 1 δ arctan ( δ sin θ sin ϕ sin ψ α 2 1 α 2 cos θ cos ϕ cos ψ ) ,

    were added which indicate that care must be taken with the multivalued functions in (19.11.5). See (Cayley, 1961, pp. 103-106).

  • Equation (10.22.72)
    10.22.72 0 J μ ( a t ) J ν ( b t ) J ν ( c t ) t 1 μ d t = ( b c ) μ 1 sin ( ( μ ν ) π ) ( sinh χ ) μ 1 2 ( 1 2 π 3 ) 1 2 a μ e ( μ 1 2 ) i π Q ν 1 2 1 2 μ ( cosh χ ) , μ > 1 2 , ν > 1 , a > b + c , cosh χ = ( a 2 b 2 c 2 ) / ( 2 b c )

    Originally, the factor on the right-hand side was written as ( b c ) μ 1 cos ( ν π ) ( sinh χ ) μ 1 2 ( 1 2 π 3 ) 1 2 a μ , which was taken directly from Watson (1944, p. 412, (13.46.5)), who uses a different normalization for the associated Legendre function of the second kind Q ν μ . Watson’s Q ν μ equals sin ( ( ν + μ ) π ) sin ( ν π ) e μ π i Q ν μ in the DLMF.

  • Section 1.14

    There have been extensive changes in the notation used for the integral transforms defined in §1.14. These changes are applied throughout the DLMF. The following table summarizes the changes.

    Transform New Abbreviated Old
    Notation Notation Notation
    Fourier ( f ) ( x ) f ( x )
    Fourier Cosine c ( f ) ( x ) c f ( x )
    Fourier Sine s ( f ) ( x ) s f ( x )
    Laplace ( f ) ( s ) f ( s ) ( f ( t ) ; s )
    Mellin ( f ) ( s ) f ( s ) ( f ; s )
    Hilbert ( f ) ( s ) f ( s ) ( f ; s )
    Stieltjes 𝒮 ( f ) ( s ) 𝒮 f ( s ) 𝒮 ( f ; s )

    Previously, for the Fourier, Fourier cosine and Fourier sine transforms, either temporary local notations were used or the Fourier integrals were written out explicitly.

  • 15: 3.4 Differentiation
    If f can be extended analytically into the complex plane, then from Cauchy’s integral formula (§1.9(iii)) …The integral on the right-hand side can be approximated by the composite trapezoidal rule (3.5.2). … The integral (3.4.18) becomes …With the choice r = k (which is crucial when k is large because of numerical cancellation) the integrand equals e k at the dominant points θ = 0 , 2 π , and in combination with the factor k k in front of the integral sign this gives a rough approximation to 1 / k ! . …As explained in §§3.5(i) and 3.5(ix) the composite trapezoidal rule can be very efficient for computing integrals with analytic periodic integrands. …
