โœฆ Synopsis

Although the predictor-corrector curve tracing method has found a wide variety of significant applications, the calculation of line integrals over implicitly defined curves seems to have been overlooked. In this paper, we present two modified numerical integration techniques, namely, the modified trapezoidal and the modified Romberg rules and results of some numerical experiments for evaluating the line integral of a vector field over an implicitly defined curve. Moreover, we give a proof of an asymptotic error expansion for a modified trapezoidal rule which is a modification of that of Verlinden and Cools [8].

This paper is concerned with the numerical integration of functions by piecewise polynomial product integration rules followed by application of extrapolation procedures. The studied rules can be considered as generalizations of the conventional trapezoidal rule. Euler-MacLaurin type asymptotic expa

When a method of numerical integration is implemented on a computer, it is performed with a limited precision arithmetic. This causes a computing error propagated at the level of each elementary operation and affecting, like the method error, the final computed result. The global error depends on t
