Integrand size = 23, antiderivative size = 147 \[ \int (d \sec (e+f x))^m (a+b \tan (e+f x))^2 \, dx=\frac {a b (2+m) (d \sec (e+f x))^m}{f m (1+m)}+\frac {d \left (b^2-a^2 (1+m)\right ) \operatorname {Hypergeometric2F1}\left (\frac {1}{2},\frac {1-m}{2},\frac {3-m}{2},\cos ^2(e+f x)\right ) (d \sec (e+f x))^{-1+m} \sin (e+f x)}{f (1-m) (1+m) \sqrt {\sin ^2(e+f x)}}+\frac {b (d \sec (e+f x))^m (a+b \tan (e+f x))}{f (1+m)} \]
