Calculation of a class of abnormal integral problems based on bivariate transformation
Aiming at the abnormal integration problem of a class of rational fractions with ax4+bx2+c in the denominator of the integrand function,by introducing bivariate transformation method and combining the combination calculation method with the theory of transforming high order rational fractions into partial rational true fractions,the calculation method for integration problems is proposed.Using the given conclusion,two type of integration problem is calculated and proved.
