摘要
讨论一类分母为多项式二次幂的有理分式的特殊积分法,得到积分公式,并加以推广.新方法有别于将有理分式化为部分分式之和的常用方法.
In this paper, a simple method for integrating certain rational functions is given. Instead of using partial fractions for rational functions, our method is formula based with coefficients to be determined by solving linear equations. Similar formula is also provided for integrating certain trigonometric rational functions.
