In this paper, the efficient methods based on the Sinc approximation with the single exponential (SE) and double exponential (DE) transformations are presented to solve nonlinear Fredholm-Volterra integral equations with weakly singular kernel. Sinc approximation has considerable advantages. Some of them are the exponential convergence of an approximate solution and simply implementation, even in the presence of singularities. Properties of the SE-Sinc and DE-Sinc methods are utilized to reduce
