In this paper, the sinc-Galerkin method is used
for numerically solving a class of nonlinear differential
equations with boundary conditions. The importance of
this study is that sinc approximation of the nonlinear term
is stated as a new theorem. The method introduced here is
tested on some nonlinear problems and is shown to be a
very efficient and powerful tool for obtaining approximate
solutions of nonlinear ordinary differential equations.
