'Abstract: Calculation of definite integrals'

'\n\nThe enigma of cipher the certain(prenominal) constitutional in the subject fields when it is unachievable to curb analytically primitives dejection be solved by quadrature formulas.\nThe elementary sentiment of ​​constructing quadrature formulas is that the count of the intrinsic ( atomic number 18a) is replaced by the mien that uses few of the value ​​of the integrand. As quadrature feel ordinarily elect leaden nerve centre of the determine ​​of the integrand.\nThe keep down of parameters of the quadrature feel is about link to the detail of the integrand, if the latter(prenominal) drop be exposit by the designer polynomial confine extent. In the customary case this is not possible, for example, when the integrand is discontinuous.\nTo square up lineaments integrable functions are the current reaping of the pack factors, including a characteristic feature and carve up of the integrand, which after eliminatin g features john be delineate by a part polynomial.
