| Abstract: | 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. |
| Keywords: | rational function indefinite integral formula of integration |
