We specifically propose a numerical approach for the solution of a nonlinear singular perturbed problem with integral boundary conditions. To solve the nonlinear singularly perturbed issue, we also apply finite difference methods. It explores how a specific derivative and a problem-solving approach behave. Finally, a numerical technique that employs a finite difference scheme is built using a nonuniform mesh.eninfo:eu-repo/semantics/openAccessSingularly Perturbed ProblemNumerical SolutionBoundary LayerUniform ConvergenceBakhvalov-Shishkin MeshSingular PerturbationError AnalysisFinite Difference SchemeBakhvalov–Shishkin MeshArticle
