\[ \boxed {\sin \left (x \right ) y^{2}+x y^{3} \cos \left (x \right )+\left (\sin \left (x \right ) x y+x y^{3} \cos \left (x \right )\right ) y^{\prime }=0} \]

Solution by Maple

Time used: 0.031 (sec). Leaf size: 5

dsolve((y(x)^2*sin(x)+x*y(x)^3*cos(x))+(x*sin(x)*y(x)+x*y(x)^3*cos(x))*diff(y(x),x)=0,y(x), singsol=all)
 

\[ y \left (x \right ) = 0 \]

Solution by Mathematica

Time used: 0.0 (sec). Leaf size: 0

DSolve[(y[x]^2*Sin[x]+x*y[x]^3*Cos[x])+(x*Sin[x]*y[x]+x*y[x]^3*Cos[x])*y'[x]==0,y[x],x,IncludeSingularSolutions -> True]
