65.1 Problem number 363

\[ \int \frac {\tan ^5(e+f x)}{\left (a+b \sec ^2(e+f x)\right )^3} \, dx \]

Optimal antiderivative \[ \frac {\left (a +b \right )^{2}}{4 a^{3} f \left (b +a \left (\cos ^{2}\left (f x +e \right )\right )\right )^{2}}+\frac {-a -b}{a^{3} f \left (b +a \left (\cos ^{2}\left (f x +e \right )\right )\right )}-\frac {\ln \left (b +a \left (\cos ^{2}\left (f x +e \right )\right )\right )}{2 a^{3} f} \]

command

integrate(tan(f*x+e)**5/(a+b*sec(f*x+e)**2)**3,x)
