§19.37(i) Introduction

Only tables published since 1960 are included. For earlier tables see Fletcher (1948), Lebedev and Fedorova (1960), and Fletcher et al. (1962).

§19.37(ii) Legendre’s Complete Integrals

Functions K(k) and E(k)

Tabulated for k2=0(.01)1 to 6D by Byrd and Friedman (1971), to 15D for K(k) and 9D for E(k) by Abramowitz and Stegun (1964, Chapter 17), and to 10D by Fettis and Caslin (1964).

Tabulated for k=0(.01)1 to 10D by Fettis and Caslin (1964), and for k=0(.02)1 to 7D by Zhang and Jin (1996, p. 673).

Tabulated for arcsink=0(1)90 to 6D by Byrd and Friedman (1971) and to 15D by Abramowitz and Stegun (1964, Chapter 17).

Functions K(k), K(k), and iK(k)/K(k)

Tabulated with k=Reiθ for R=0(.01)1 and θ=0(1)90 to 11D by Fettis and Caslin (1969).

Function exp(πK(k)/K(k))(=q(k))

Tabulated for k2=0(.01)1 to 6D by Byrd and Friedman (1971) and to 15D by Abramowitz and Stegun (1964, Chapter 17).

Tabulated for arcsink=0(1)90 to 6D by Byrd and Friedman (1971) and to 15D by Abramowitz and Stegun (1964, Chapter 17).

Tabulated for k2=0(.001)1 to 8D by Beli͡akov et al. (1962).

§19.37(iii) Legendre’s Incomplete Integrals

Functions F(ϕ,k) and E(ϕ,k)

Tabulated for ϕ=0(5)90, k2=0(.01)1 to 10D by Fettis and Caslin (1964).

Tabulated for ϕ=0(1)90, k2=0(.01)1 to 7S by Beli͡akov et al. (1962). (F(ϕ,k) is presented as Π(ϕ,0,k).)

Tabulated for ϕ=0(5)90, k=0(.01)1 to 10D by Fettis and Caslin (1964).

Tabulated for ϕ=0(5)90, arcsink=0(1)90 to 6D by Byrd and Friedman (1971), for ϕ=0(5)90, arcsink=0(2)90 and 5(10)85 to 8D by Abramowitz and Stegun (1964, Chapter 17), and for ϕ=0(10)90, arcsink=0(5)90 to 9D by Zhang and Jin (1996, pp. 674–675).

Function Π(ϕ,α2,k)

Tabulated (with different notation) for ϕ=0(15)90, α2=0(.1)1, arcsink=0(15)90 to 5D by Abramowitz and Stegun (1964, Chapter 17), and for ϕ=0(15)90, α2=0(.1)1, arcsink=0(15)90 to 7D by Zhang and Jin (1996, pp. 676–677).

Tabulated for ϕ=5(5)80(2.5)90, α2=1(.1)0.1,0.1(.1)1, k2=0(.05)0.9(.02)1 to 10D by Fettis and Caslin (1964) (and warns of inaccuracies in Selfridge and Maxfield (1958) and Paxton and Rollin (1959)).

Tabulated for ϕ=0(1)90, α2=0(.05)0.85,0.88(.02)0.94(.01)0.98(.005)1, k2=0(.01)1 to 7S by Beli͡akov et al. (1962).

§19.37(iv) Symmetric Integrals

Functions RF(x2,1,y2) and RG(x2,1,y2)

Tabulated for x=0(.1)1, y=1(.2)6 to 3D by Nellis and Carlson (1966).

Function RF(a2,b2,c2) with abc=1

Tabulated for σ=0(.05)0.5(.1)1(.2)2(.5)5, cos(3γ)=1(.2)1 to 5D by Carlson (1961a). Here σ2=23((lna)2+(lnb)2+(lnc)2), cos(3γ)=(4/σ3)(lna)(lnb)(lnc), and a,b,c are semiaxes of an ellipsoid with the same volume as the unit sphere.

Check Values

For check values of symmetric integrals with real or complex variables to 14S see Carlson (1995).
