Application of the Sinc Approximation to the Solution of Bratuʹʹs Problem

In this work, we study the performance of the sinc-Collocation method for solving Bratuʹs 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 verified that this method converges to the exact solution rapidly and with O(exp (-c)) accuracy where c is independent of n.
