4.1 Problem number 497

\[ \int \sec (c+d x) (a+b \sin (c+d x))^{5/2} \, dx \]

Optimal antiderivative \[ -\frac {\left (a -b \right )^{\frac {5}{2}} \arctanh \! \left (\frac {\sqrt {a +b \sin \left (d x +c \right )}}{\sqrt {a -b}}\right )}{d}+\frac {\left (a +b \right )^{\frac {5}{2}} \arctanh \! \left (\frac {\sqrt {a +b \sin \left (d x +c \right )}}{\sqrt {a +b}}\right )}{d}-\frac {2 b \left (a +b \sin \! \left (d x +c \right )\right )^{\frac {3}{2}}}{3 d}-\frac {4 a b \sqrt {a +b \sin \! \left (d x +c \right )}}{d} \]
