Optimal result

Integrand size = 19, antiderivative size = 89 \[ \int \sec ^n(e+f x) (a \sin (e+f x))^m \, dx=-\frac {a \operatorname {Hypergeometric2F1}\left (\frac {1-m}{2},\frac {1-n}{2},\frac {3-n}{2},\cos ^2(e+f x)\right ) \sec ^{-1+n}(e+f x) (a \sin (e+f x))^{-1+m} \sin ^2(e+f x)^{\frac {1-m}{2}}}{f (1-n)} \] Output:
