To evaluate the integral
we can start by performing polynomial long division since the degree of the numerator is higher than the degree of the denominator.
- Perform Polynomial Long Division:
Dividing
by
:
-
The first term in the quotient is
. -
Multiply
by which gives: -
Subtracting this from the original numerator gives:
-
The next term in the quotient is
. -
Multiplying by
gives: -
Subtracting this gives:
-
The last term is
as a constant term. -
Multiply
by : -
Subtracting gives:
So, we have:
- Rewriting the Integral:
Now substituting this back into the integral:
- Integrating Each Term:
We can integrate each term separately:
Calculating these integrals:
-
, -
, -
, - For
, we use the substitution , or :
Combining all the results:
where
is the constant of integration.
Thus, the evaluated integral is:

\int \frac{3\theta{3}-7\theta{2}+13\theta}{3\theta-4} , d\theta = \frac{\theta^3}{3} - \frac{\theta^2}{2} + 3\theta + 4 \ln |3\theta
\int \frac{3\theta{3}-7\theta{2}+13\theta}{3\theta-4} , d\theta = \frac{\theta^3}{3} - \frac{\theta^2}{2} + 3\theta + 4 \ln |3\theta
