The Expansion of an Arbitrary Function in Terms of an Integral of Associated Legendre Functions of ding a given function ψ.(x) in an integral of associated Legendre functions. The necessity of such transformations arises, for example, in problems related to the use of toroidal and ellipsoidal coordinates.

Solution of Three-Dimensional Problems for the Hyperboloid of Revolution and the Lens in Electricalthe coefficients, a generalization of the Mehler-Fok integral theorem to the case . ft is used. The final expressions for the potential functions are given in the form of series whose coefficients are given by real integrals.
