Timed out. \[ \int \frac {1}{\left (d-e x^2\right )^2 \sqrt {d^2-e^2 x^4}} \, dx=\int \frac {1}{\sqrt {d^2-e^2\,x^4}\,{\left (d-e\,x^2\right )}^2} \,d x \] Input:

int(1/((d^2 - e^2*x^4)^(1/2)*(d - e*x^2)^2),x)
 

Output:

int(1/((d^2 - e^2*x^4)^(1/2)*(d - e*x^2)^2), x)
 

Reduce [F]

\[ \int \frac {1}{\left (d-e x^2\right )^2 \sqrt {d^2-e^2 x^4}} \, dx=\int \frac {\sqrt {-e^{2} x^{4}+d^{2}}}{-e^{4} x^{8}+2 d \,e^{3} x^{6}-2 d^{3} e \,x^{2}+d^{4}}d x \] Input:

int(1/(-e*x^2+d)^2/(-e^2*x^4+d^2)^(1/2),x)
 

Output:

int(sqrt(d**2 - e**2*x**4)/(d**4 - 2*d**3*e*x**2 + 2*d*e**3*x**6 - e**4*x* 
*8),x)
