\[ \boxed { \sin \left ( x \right ) \cos \left ( x \right ) {\frac {\rm d}{{\rm d}x}}y \left ( x \right ) -y \left ( x \right ) - \left ( \sin \left ( x \right ) \right ) ^{3}=0} \]
Mathematica: cpu = 0.024503 (sec), leaf count = 15 \[ \left \{\left \{y(x)\to c_1 \tan (x)-\sin (x)\right \}\right \} \]
Maple: cpu = 0.0 (sec), leaf count = 15 \[ \left \{ y \left ( x \right ) =-\cos \left ( x \right ) \tan \left ( x \right ) +\tan \left ( x \right ) {\it \_C1} \right \} \]
