\[ \int \frac {A+B \tan (c+d x)}{(a+b \tan (c+d x))^{3/2}} \, dx \]
Optimal antiderivative \[ -\frac {\left (i A +B \right ) \arctanh \left (\frac {\sqrt {a +b \tan \left (d x +c \right )}}{\sqrt {-i b +a}}\right )}{\left (-i b +a \right )^{\frac {3}{2}} d}+\frac {\left (i A -B \right ) \arctanh \left (\frac {\sqrt {a +b \tan \left (d x +c \right )}}{\sqrt {i b +a}}\right )}{\left (i b +a \right )^{\frac {3}{2}} d}-\frac {2 \left (A b -B a \right )}{\left (a^{2}+b^{2}\right ) d \sqrt {a +b \tan \left (d x +c \right )}} \]
