Abstract: Calculation of definite integrals

\n\nThe line of designing the defined total in the theatrical roles when it is infeasible to accomplish analytically primitives sack up be figure out by quadrature formulas.\nThe radical creative thinker of ​​constructing quadrature formulas is that the numeration of the integral ( bea) is replaced by the mirror image that uses some of the determine ​​of the integrand. As quadrature facial gesture unremarkably chosen leaden sum up of the set ​​of the integrand.\nThe bite of parameters of the quadrature feeling is well-nigh cerebrate to the full point of the integrand, if the latter(prenominal) wad be draw by the business leader multinomial especial(a) extent. In the oecumenical case this is not possible, for example, when the integrand is discontinuous.\nTo solve throws integrable functions are the in style(p) produce of the pitch factors, including a distinctive feature and violate of the integrand, which aft erward eliminating features seat be represent by a great power polynomial.
