✦ Synopsis

Atmtract~We give sharp error estimates for both function and derivative when the coefficients and right hand side of a given initial or boundary value problem for ordinary differential equations are replaced by local appro3dmations. These estimates are given for partition points and also contlnuously on subintervals. Numerical examples demonstrate the accuracy of our estimates.
