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

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

Output:

int(sqrt(tan(c + d*x)*b + a)*sqrt(cot(c + d*x))*cot(c + d*x),x)
