S>Convergence of the expansion of the cosine dependence of the amplitude employed in the deduction of the integral equations from the Mandelstam representation is investigated in the case of pi - pi scattering. An equation set for low energies is presented in which rapid convergence of the expansion of the real part of the amplitude can be attained by a conformal mapping of the cosine plane. Since any power of the function employed contains an infinite number of partial waves this approach should be especially convenient in those cases when high number waves may be important.
