Kvadratury Newton-Cotesova typu

Abstract

In present work we study one of a method on approximation definite integral and important factors which in fluence convergency. It is Newton - Cotes formula. next in work is processed expansion formula on two-dimension problems. Here is describe a Romberg method too. The method is derive just from Newton - Cotes quadrature. Therefore we compare this two method. Single parts are completed with examples which refiect problems with using these formulae.
