Optimal result

Integrand size = 21, antiderivative size = 92 \[ \int (b \sec (e+f x))^n (a \sin (e+f x))^m \, dx=-\frac {a b \operatorname {Hypergeometric2F1}\left (\frac {1-m}{2},\frac {1-n}{2},\frac {3-n}{2},\cos ^2(e+f x)\right ) (b \sec (e+f x))^{-1+n} (a \sin (e+f x))^{-1+m} \sin ^2(e+f x)^{\frac {1-m}{2}}}{f (1-n)} \] Output:
