Abstrakt: This study employs Richardson extrapolation on mixed quadrature rule which is imbraided by Lobatto-4-point rule (RLA(f)) with Gauss-Legendre-3-point rule (RGL3 (f)) to form the extrapolatory quadrature rule (RRLAG13 (f)) Of precision nine. The current rule is numerically verified with six test problems and the bound for the error is resolved with suitable examples. [ABSTRACT FROM AUTHOR]
