int(1/(x*cot(a + b*log(c*x^n))^(1/2)),x)
 

Output:

((-1)^(1/4)*atan((-1)^(1/4)*cot(a + b*log(c*x^n))^(1/2))*1i)/(b*n) + ((-1) 
^(1/4)*atanh((-1)^(1/4)*cot(a + b*log(c*x^n))^(1/2))*1i)/(b*n)
 

Reduce [F]

\[ \int \frac {1}{x \sqrt {\cot \left (a+b \log \left (c x^n\right )\right )}} \, dx=\int \frac {\sqrt {\cot \left (\mathrm {log}\left (x^{n} c \right ) b +a \right )}}{\cot \left (\mathrm {log}\left (x^{n} c \right ) b +a \right ) x}d x \] Input:

int(1/x/cot(a+b*log(c*x^n))^(1/2),x)
 

Output:

int(sqrt(cot(log(x**n*c)*b + a))/(cot(log(x**n*c)*b + a)*x),x)
