Abstract: The numerical integration of functions with a boundary-layer component whose derivatives are not uniformly bounded is investigated. The Newton-Cotes formulas as applied to such functions can lead to significant errors. An analogue of Newton-Cotes formulas that is exact for the boundary-layer component is constructed. For the resulting formula, an error estimate that is uniform with respect to the boundary-layer component and its derivatives is obtained. Numerical results that agree with the error estimates are presented.
Key words: one-variable functions with a boundary-layer component, definite integral, modification of Newton–Cotes formulas, error estimate.
