An Effective Approximation Algorithm for Second-Order Singular Functional Differential Equations

In this research study, a novel computational algorithm for solving second-order singular functional differential equation as generalization of the well-known Lane–Emden and differential-difference equations is presented by using Bessel bases. This technique depends on transforming problem into system algebraic unknown coefficients are determined solution will be known. The method tested several test examples proves to provide accurate results compared other existing methods from literature. simplicity robustness proposed drive us investigate more their applications similar problems in future.
