Rashidinia Department of Mathematics, Islamic Azad University,Central Tehran Branch, Iran Iran, Islamic Republic of N. Taher Iran, Islamic Republic of Journal Article 2016 06 21 In this work, we study the performance of the sinc-Collocation method for solving Bratu's problem. For different choices of step size, we consider the maximum absolute errors in the solutions at sinc grid points and tabulated in tables. The comparison of the obtained results veri ed that this method converges to the exact solution rapidly and with
