int(sin(e + f*x)^3*(a + b*tan(e + f*x)^2)^(3/2), x)
\[ \int \sin ^3(e+f x) \left (a+b \tan ^2(e+f x)\right )^{3/2} \, dx=\left (\int \sqrt {\tan \left (f x +e \right )^{2} b +a}\, \sin \left (f x +e \right )^{3} \tan \left (f x +e \right )^{2}d x \right ) b +\left (\int \sqrt {\tan \left (f x +e \right )^{2} b +a}\, \sin \left (f x +e \right )^{3}d x \right ) a \] Input:
int(sin(f*x+e)^3*(a+b*tan(f*x+e)^2)^(3/2),x)
Output:
int(sqrt(tan(e + f*x)**2*b + a)*sin(e + f*x)**3*tan(e + f*x)**2,x)*b + int (sqrt(tan(e + f*x)**2*b + a)*sin(e + f*x)**3,x)*a
