Fricas [B] (verification not implemented)

Both result and optimal contain complex but leaf count of result is larger than twice the leaf count of optimal. 1154 vs. \(2 (271) = 542\).

Time = 0.46 (sec) , antiderivative size = 1154, normalized size of antiderivative = 3.71 \[ \int \frac {(e+f x) \sin ^2(c+d x)}{a+b \sin (c+d x)} \, dx=\text {Too large to display} \]
