    Differential Equation Question

    I need to prove that the solution of this differential equation: dx/dt = -x3 + 2*x + sin3(2*pi*t) - 2*sin(2*pi*t) + 2*pi*sin(2*pi*t) has the solution: ψ(t,0,0) = sin(2*pi*t) I know that I need to get all of the x's on one side and the t's on the other then integrate, but I cant...
