DSolve[y'[x] == (Cot[x] + 2*Csc[2*x])*y[x],y[x],x]
Mathematica raw output
{{y[x] -> (C[1]*Sin[x]^(3/2)*Sqrt[Sin[2*x]])/Cos[x]^(3/2)}}
Maple raw input
dsolve(diff(y(x),x) = (2*csc(2*x)+cot(x))*y(x), y(x),'implicit')
Maple raw output
y(x) = _C1*cot(x)*(cos(x)-cos(3*x))/(cot(x)^2*sin(2*x)+2*cot(x)-sin(2*x))
