Timed out. \[ \int \frac {\sqrt {\cot (c+d x)}}{(a+i a \tan (c+d x))^{3/2}} \, dx=\int \frac {\sqrt {\mathrm {cot}\left (c+d\,x\right )}}{{\left (a+a\,\mathrm {tan}\left (c+d\,x\right )\,1{}\mathrm {i}\right )}^{3/2}} \,d x \] Input:

int(cot(c + d*x)^(1/2)/(a + a*tan(c + d*x)*1i)^(3/2),x)
 

Output:

int(cot(c + d*x)^(1/2)/(a + a*tan(c + d*x)*1i)^(3/2), x)
 

Reduce [F]

\[ \int \frac {\sqrt {\cot (c+d x)}}{(a+i a \tan (c+d x))^{3/2}} \, dx=\frac {\int \frac {\sqrt {\cot \left (d x +c \right )}}{\sqrt {\tan \left (d x +c \right ) i +1}\, \tan \left (d x +c \right ) i +\sqrt {\tan \left (d x +c \right ) i +1}}d x}{\sqrt {a}\, a} \] Input:

int(cot(d*x+c)^(1/2)/(a+I*a*tan(d*x+c))^(3/2),x)
 

Output:

int(sqrt(cot(c + d*x))/(sqrt(tan(c + d*x)*i + 1)*tan(c + d*x)*i + sqrt(tan 
(c + d*x)*i + 1)),x)/(sqrt(a)*a)
