%0 Journal Article %T The Estimation of the Error at Richardson¡¯s Extrapolation and the Numerical Solution of Integral Equations of the Second Kind %A Igor Petrovich Dobrovolsky %J Open Access Library Journal %V 2 %N 11 %P 1-7 %@ 2333-9721 %D 2015 %I Open Access Library %R 10.4236/oalib.1102051 %X The mode of definition of the error at polynomial Richardson¡¯s extrapolation is described. Along with the table of extrapolations the new magnitudes reflecting expediency and efficiency of extrapolation are entered. On concrete examples it is shown that application of Richardson¡¯s extrapolation to a solution of integral equations has appeared rather effective and gives a solution with a high exactitude. Application of formulas of interpolation leads to a solution in the analytical aspect. %K The Trapezoidal Rule %K Continued Fraction %K The Index of Richardson¡¯s Extrapolation %U http://www.oalib.com/paper/3151652
