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.eninfo:eu-repo/semantics/openAccessnonlinearitysinc-Galerkin methodboundary value problemsArticle13138939410.1515/phys-2015-00502-s2.0-84954182707Q2WOS:000369101700033Q4
