Integrand size = 30, antiderivative size = 97 \[ \int \frac {(c-c \sin (e+f x))^{3/2}}{(a+a \sin (e+f x))^{3/2}} \, dx=-\frac {c^2 \cos (e+f x) \log (1+\sin (e+f x))}{a f \sqrt {a+a \sin (e+f x)} \sqrt {c-c \sin (e+f x)}}-\frac {c \cos (e+f x) \sqrt {c-c \sin (e+f x)}}{f (a+a \sin (e+f x))^{3/2}} \] Output:
