INTEGRALS CONTAINING ax+b AND px+q

1.
$\displaystyle \int\displaystyle \frac{dx}{(ax+b)(px+q)}=\displaystyle \frac{1}{bp-aq}\ln\left(\displaystyle \frac{px+q}{ax+b}\right)$

2.
$\displaystyle \int\displaystyle \frac{x\,dx}{(ax+b)(px+q)}=\displaystyle \frac{...
...\{\displaystyle \frac{b}{a}\ln(ax+b)-\displaystyle \frac{q}{p}\ln(px+q)\right\}$

3.
$\displaystyle \int\displaystyle \frac{dx}{(ax+b)^{\displaystyle
2}(px+q)}=\disp...
...laystyle \frac{p}{bp-aq}\ln\left(\displaystyle \frac{px+q}{ax+b}\right)\right\}$

4.
$\displaystyle \int\displaystyle \frac{x\,dx}{(ax+b)^{\displaystyle2}(px+q)}=\di...
...(\displaystyle \frac{ax+b}{px+q}\right)-\displaystyle \frac{b}{a(ax+b)}\right\}$

5.
$\displaystyle\begin{array}{l}
\displaystyle \int\displaystyle \frac{x^{\display...
...\displaystyle \frac{b(bp-2aq)}{a^{\displaystyle2}}\ln(ax+b)\right\}
\end{array}$

\end{array}$

7.
$\displaystyle \int\displaystyle \frac{ax+b}{px+q}\,dx=\displaystyle \frac{ax}{p}+\displaystyle \frac{bp-aq}{p^{\displaystyle2}}\ln(px+q)$
