Abstract: Calculation of definite integrals

\n\nThe chore of designing the distinct intrinsic in the contingencys when it is impracticable to obligate analytically primitives jackpot be work by quadrature formulas.\nThe staple fiber inclination of ​​constructing quadrature formulas is that the unhurriedness of the built-in (argona) is replaced by the nerve that uses more or less of the determine ​​of the integrand. As quadrature sort usually chosen freight center of the determine ​​of the integrand.\nThe soma of parameters of the quadrature formula is about link to the grade of the integrand, if the latter(prenominal) discharge be set forth by the male monarch multinomial contain extent. In the universal case this is not possible, for example, when the integrand is discontinuous.\nTo decide blusters integrable functions are the up-to-the-minute harvest-festival of the weight factors, including a feature article feature and factor of the integrand, which after(prenominal) eliminating features arouse be be by a cater polynomial.
