ધારો કે $\frac{1}{x^{2}-9} = \frac{1}{(x+3)(x-3)}$.
આંશિક અપૂર્ણાંકની રીતનો ઉપયોગ કરતા,$\frac{1}{(x+3)(x-3)} = \frac{A}{x+3} + \frac{B}{x-3}$.
બંને બાજુ $(x+3)(x-3)$ વડે ગુણતા,આપણને $1 = A(x-3) + B(x+3)$ મળે છે.
$x = 3$ લેતા,$1 = B(6)$,તેથી $B = \frac{1}{6}$.
$x = -3$ લેતા,$1 = A(-6)$,તેથી $A = -\frac{1}{6}$.
આમ,$\int \frac{1}{x^{2}-9} dx = \int \left( \frac{-1/6}{x+3} + \frac{1/6}{x-3} \right) dx$.
$= -\frac{1}{6} \int \frac{1}{x+3} dx + \frac{1}{6} \int \frac{1}{x-3} dx$.
$= -\frac{1}{6} \ln |x+3| + \frac{1}{6} \ln |x-3| + C$.
$= \frac{1}{6} \ln \left| \frac{x-3}{x+3} \right| + C$,જ્યાં $C$ એ સંકલનનો અચળાંક છે.
