Reduce [F]

\[ \int \frac {(a+b \arccos (c x)) \log \left (h (f+g x)^m\right )}{\sqrt {1-c^2 x^2}} \, dx=\left (\int \frac {\mathrm {log}\left (\left (g x +f \right )^{m} h \right )}{\sqrt {-c^{2} x^{2}+1}}d x \right ) a +\left (\int \frac {\mathit {acos} \left (c x \right ) \mathrm {log}\left (\left (g x +f \right )^{m} h \right )}{\sqrt {-c^{2} x^{2}+1}}d x \right ) b \] Input:

int((a+b*acos(c*x))*log(h*(g*x+f)^m)/(-c^2*x^2+1)^(1/2),x)
 

Output:

int(log((f + g*x)**m*h)/sqrt( - c**2*x**2 + 1),x)*a + int((acos(c*x)*log(( 
f + g*x)**m*h))/sqrt( - c**2*x**2 + 1),x)*b
